From [http://www.xfce.org/about/ Xfce - About]:
+
[http://www.xfce.org Xfce] is a lightweight and modular [[desktop environment]] currently based on GTK+ 2. To provide a complete user experience, it includes a window manager, a file manager, desktop and panel.
  
:''Xfce embodies the traditional UNIX philosophy of modularity and re-usability. It consists of a number of components that provide the full functionality one can expect of a modern desktop environment. They are packaged separately and you can pick among the available packages to create the optimal personal working environment.''
+
== Installation ==
  
Xfce is a Desktop Environment, like [[GNOME]] or [[KDE]]. It contains a suite of apps like a root window app, window manager, file manager, panel, etc. Xfce is written using the GTK2 toolkit, and contains its own development environment (libraries, daemons, etc), similar to other big DEs. Features:
+
[[Install]] the {{Grp|xfce4}} group. You may also wish to install the {{Grp|xfce4-goodies}} group which includes extra plugins and a number of useful utilities such as the {{Pkg|mousepad}} editor. Xfce uses the [[Xfwm]] window manager by default.
*Lighter on resources than the other major DEs (KDE, GNOME).
 
*Most settings are exposed via a GUI, Xfce does not try to hide stuff from the user.
 
*Xfwm has an optional built-in compositor which allows for true transparency and all the benefits of GPU acceleration (minimizes tearing, etc.).
 
*It works great with multiple monitors.
 
 
 
==Installation==
 
 
 
Before starting, make sure you have the [[Xorg|X server]] installed and configured correctly.
 
 
 
{{Note|Xfce is somewhat modular. That means there is no need for you to run every part, you can pick and choose some of them.}}
 
 
 
The base Xfce system can be [[pacman|installed]] with the group {{Grp|xfce4}}, available in the [[Official Repositories]]. Pacman will ask you to select the packages to install, but you probably want to get them all by simply pressing {{Keypress|Enter}}. Additional packages, like panel plugins, notifications, and system tools are available in the {{Grp|xfce4-goodies}} group.
 
 
 
{{Tip|
 
* Installing [[Gamin]] (the successor of [[FAM]]) is highly recommended.
 
* Common tasks such as mounting removable drives and extracting archives can be accomplished with Thunar. If you do not install {{Grp|xfce4-goodies}} but still want these niceties, read the [[Thunar]] page.}}
 
  
 
== Starting Xfce ==
 
== Starting Xfce ==
=== Automatically ===
 
There are two methods to start Xfce (and in fact, any desktop or window manager) at boot time:
 
  
* Run Xfce through a [[Display Manager]]
+
Choose ''Xfce Session'' from the menu in a [[display manager]] of choice, or add {{ic|exec startxfce4}} to [[Xinitrc]].
* Run Xfce automatically using the {{pkg|xorg-xinit}} method at [[Start X at Login]] combining with [[Automatic login to virtual console‎ ]]
 
  
=== Manually ===
+
{{Note|Do not call the {{ic|xfce4-session}} executable directly; {{ic|startxfce4}} is the correct command which, in turn, calls the former when appropriate.}}
  
There are two methods to start Xfce manually:
+
== Configuration ==
  
* Run {{ic|startxfce4}} directly from the console.
+
Xfce stores configuration options in [http://docs.xfce.org/xfce/xfconf/start Xfconf]. There are several ways to modify these options:
* Configure {{ic|~/.xinitrc}} to {{ic|exec startxfce4}} and then run {{ic|xinit}} or {{ic|startx}} from the console. See [[xinitrc]] for details.
 
  
{{Note|The proper command for launching Xfce is {{ic|startxfce4}}, do not start {{ic|xfce4-session}} directly.}}
+
* In the main menu, select [http://docs.xfce.org/xfce/xfce4-settings/start Settings] and the category you want to customize. Categories are programs usually located in {{ic|/usr/bin/xfce4-*}} and {{ic|/usr/bin/xfdesktop-settings}}.
 +
* {{ic|xfce4-settings-editor}} can see and modify all settings. Options modified here will take effect immediately. Use {{ic|xfconf-query}} to change settings from the commandline; see [http://docs.xfce.org/xfce/xfconf/xfconf-query the documentation] for details.
 +
* Settings are stored in XML files in {{ic|~/.config/xfce4/xfconf/xfce-perchannel-xml/}} which can be edited by hand. However, changes made here will ''not'' take effect immediately.
  
=== Automounting ===
+
=== Menu ===
See [[General Troubleshooting#Session permissions]].
 
  
If you have no problems shutting down and rebooting but cannot automount external media and disks, you may need to install {{pkg|gvfs}}. See the [[#Removable Devices|Removable Devices]] section.
+
See [[Xdg-menu]] for more info on using the Free Desktop menu system.
  
==Tips and tricks==
+
==== Whisker menu ====
===Xfconf settings===
 
Xfconf is XFCE's system for storing configuration options, and most XFCE configuration is done by editing settings in Xfconf (one way or another). There are several ways to modify these settings:
 
* The most obvious and easiest way is to go to "Settings" in the main menu and select the category you want to customize. However, not all customization options are available this way.
 
* A less user-friendly but more general way is to go to {{bc|Main menu -> Settings -> Settings Editor}} where you can see and modify all the customization options. Any settings modified here will take effect immediately. The Settings Editor can also be launched from the command line by invoking {{ic|xfce4-settings-editor}}.
 
* Customization can be done completely from the command line using the program {{ic|xfconf-query}}. See [http://docs.xfce.org/xfce/xfconf/xfconf-query the XFCE online documentation] for more information and examples and the rest of this wiki page for more examples. Settings changed here will take effect immediately.
 
* The settings are stored in XML files in {{ic|~/.config/xfce4/xfconf/xfce-perchannel-xml/}} which can be edited by hand. However, changes made here will not take effect immediately.
 
* For more information: [http://docs.xfce.org/xfce/xfconf/start Xfconf documentation]
 
===Panel===
 
====xfce panel background====
 
Edit {{ic|~/.gtkrc-2.0}}.
 
Note that you must place the image in the same directory as the configuration, which is {{ic|~/}}. You can not specify the path to the image, or it will not work.
 
  style "panel-background" {
 
    bg_pixmap[NORMAL]        = "foo.bar"
 
    bg_pixmap[PRELIGHT]      = "foo.bar"
 
    bg_pixmap[ACTIVE]        = "foo.bar"
 
    bg_pixmap[SELECTED]      = "foo.bar"
 
    bg_pixmap[INSENSITIVE]  = "foo.bar"
 
  }
 
  widget_class "*Panel*" style "panel-background"
 
  
==== 'menu' panel replacement ====
+
{{Pkg|xfce4-whiskermenu-plugin}} (also part of {{Grp|xfce4-goodies}}) is an alternate application launcher. It shows a list of favorites, browses through all installed applications through category buttons, and supports fuzzy searching. After package being installed, it can replace 'Applications Menu' as first item in Panel 1 (in 'Settings/Panel/Items' add 'Whisker Menu'...).
The "Ubuntu System Panel" (GNOME) panel applet has similar features to those found in its KDE v4.2 equivalent. It can be added to an Xfce panel via the 'XfApplet' panel applet, which allows GNOME applets to be used in Xfce.
 
  
It is available in the [[Arch User Repository|AUR]] as the {{AUR|usp2}} package.
+
==== Edit entries ====
  
==== Removing entries from the System menu====
+
A number of graphical tools are available for this task:
===== Method 1 =====
 
With the built-in menu editor, you cannot remove menu entries from the System menu. Here’s how to hide them:
 
# Open Terminal (Xfce menu > System > Terminal) and go to the {{ic|/usr/share/applications}} folder: {{bc|$ cd /usr/share/applications}}
 
# This folder should be full of {{ic|.desktop}} files. To see a list type: {{bc|$ ls}}
 
# Add {{ic|1=NoDisplay=true}} to the {{ic|.desktop}} file. For example, if you want to hide Firefox, type in the terminal: {{bc|1=# echo "NoDisplay=true" >> firefox.desktop}} This command appends the text {{ic|1=NoDisplay=true}} to the end of the {{ic|.desktop}} file.
 
  
===== Method 2 =====
+
* {{App|MenuLibre|An advanced menu editor that provides modern features in a clean, easy-to-use interface.|https://launchpad.net/menulibre|{{AUR|menulibre}}}}.
Another method is to copy the entire contents of the global applications directory over to your local applications directory, and then proceed to modify and/or disable unwanted .desktop entries. This will survive application updates that overwrite changes under {{ic|/usr/share/applications/}}.
+
* {{App|Alacarte|Menu editor for GNOME|http://www.gnome.org/|{{Pkg|alacarte}}}}
# In a terminal, copy everything from {{ic|/usr/share/applications}} to {{ic|~/.local/share/applications/}}: {{bc|$ cp /usr/share/applications/* ~/.local/share/applications/}}
+
* {{App|XAME|GUI tool written in Gambas designed specifically for editing menu entries in Xfce, it will not work in other environments. (Discontinued)|http://www.redsquirrel87.com/XAME.php{{Dead link|2017|12|30}}|{{AUR|xame}}}}
# For any entry you wish to hide from the menu, add the {{ic|1=NoDisplay=true}} option: {{bc|1=$ echo "NoDisplay=true" >> ~/.local/share/applications/foo.desktop}}
 
  
You can also edit the application's category by editing the {{ic|.desktop}} file with a text editor and modifying the {{ic|1=Categories=}} line.
+
Alternatively, create the file {{ic|~/.config/menus/xfce-applications.menu}} manually. See the example configuration below:
  
===== Method 3 =====
 
The third method is the '''cleanest''' and recommended in the [http://wiki.xfce.org/howto/customize-menu Xfce wiki].
 
 
Create the file {{ic|~/.config/menus/xfce-applications.menu}} and copy the following in it:
 
 
  <!DOCTYPE Menu PUBLIC "-//freedesktop//DTD Menu 1.0//EN"
 
  <!DOCTYPE Menu PUBLIC "-//freedesktop//DTD Menu 1.0//EN"

===== Method 4 =====
 
Alternatively a tool called [http://www.redsquirrel87.com/XAME.html xame] can be used. XAME is a GUI tool written in Gambas designed specifically for editing menu entires in XFCE, it will NOT work in other DEs. XAME is available in the {{AUR|xame}} package from the [[AUR]].
 
 
 
==== Missing applications ====
 
When some applications are installed (for example via [[WINE]]), they may not be listed in {{ic|/usr/share/applications}}. Shortcuts ''might'' be found in the category “Other” in this directory:
 
{{ic|~/.local/share/applications/wine/}}.
 
 
 
====Panel autohide delay====
 
Add this to {{ic|~/.gtkrc-2.0}}.
 
  style "xfce-panel-window-style"
 
  {
 
    # Time in miliseconds before the panel will unhide on an enter event
 
    XfcePanelWindow::popup-delay = 225
 
 
 
    # Time in miliseconds before the panel will hide on a leave event
 
    XfcePanelWindow::popdown-delay = 350
 
  }
 
  class "XfcePanelWindow" style "xfce-panel-window-style"
 
 
 
====Panel at desktop level====
 
 
 
If you want a panel at desktop level (i.e., other windows will stack over it) you need a little hack, ensure you have installed the {{pkg|wmctrl}} package from the [[Official Repositories]].
 
 
 
Create a script in {{ic|~/.config/xfce4/xfce4-fix-panel}} with this content and make it executable (you can use {{ic|chmod 755 xfce4-fix-panel}}).
 
 
 
  #!/bin/bash
 
set -e
 
 
function getPanelIdImpl() {
 
  # get panel id
 
  PANEL="`wmctrl -l | sed -n -e '/ xfce4-panel$/ s_ .*$__ p' | sed -n -e $1' p'`"
 
}
 
 
function getPanelId() {
 
  # eventually await the panel to appear
 
  getPanelIdImpl $1
 
  while [ x = x$PANEL ] ;do
 
    sleep 0.5s
 
    getPanelIdImpl $1
 
  done
 
}
 
 
function putPanelDown() {
 
  PANEL=""
 
  getPanelId $1
 
  wmctrl -i -r $PANEL -b add,below
 
}
 
 
# call the program with a list of panel numbers as arguments
 
# for example, xfce4-fix-panel 1 2 3
 
# for the first three panels
 
for i in $* ;do
 
  putPanelDown $i
 
done
 
 
 
 
 
Once wrote the script, and tested it, you need to auto-execute it at each login. You can use the {{ic|Session and StartUp -> Application Autostart}} gui.
 
 
 
This passage will put your panels at desktop level, but if your panel is sticking to a border the maximized windows will not stack over it. You can enable this behavior with the following command, fortunately you need to do this only once. (change the $ID with the panel number of interest)
 
  
xfconf-query -c xfce4-panel -p /panels/panel-$ID/disable-struts -n -t bool -s true
+
You can also make changes to the Xfce menu by editing the {{ic|.desktop}} files themselves. To hide entries, see [[Desktop entries#Hide desktop entries]]. You can edit the application's category by modifying the {{ic|1=Categories=}} line of the desktop entry, see [[Desktop entries#File example]].
  
 
=== Desktop ===
 
=== Desktop ===
  
==== Transparent Background for Icon Titles ====
+
==== Transparent background for icon titles ====
To change the default white background of desktop icon titles to something more suitable, edit the {{ic|.gtkrc-2.0}} file in your home directory (or create the file if needed) and add the following:
 
style "xfdesktop-icon-view" {
 
XfdesktopIconView::label-alpha = 10
 
base[NORMAL] = "#000000"
 
base[SELECTED] = "#71B9FF"
 
base[ACTIVE] = "#71FFAD"
 
fg[NORMAL] = "#ffffff"
 
fg[SELECTED] = "#71B9FF"
 
fg[ACTIVE] = "#71FFAD" }
 
widget_class "*XfdesktopIconView*" style "xfdesktop-icon-view"
 
  
==== Hide Selected Partitions ====
+
To change the default white background of desktop icon titles to something more suitable, create or edit {{ic|~/.gtkrc-2.0}}:
If you wish to prevent certain partitions or drives appearing on the desktop, you can create a udev rule, for example {{ic|/etc/udev/rules.d/10-local.rules}}:
 
  
KERNEL=="sda1", ENV{UDISKS_PRESENTATION_HIDE}="1"
+
{{bc|<nowiki>
KERNEL=="sda2", ENV{UDISKS_PRESENTATION_HIDE}="1"
+
style "xfdesktop-icon-view" {
 +
    XfdesktopIconView::label-alpha = 10
 +
    base[NORMAL] = "#000000"
 +
    base[SELECTED] = "#71B9FF"
 +
    base[ACTIVE] = "#71B9FF"
 +
    fg[NORMAL] = "#fcfcfc"
 +
    fg[SELECTED] = "#ffffff"
 +
    fg[ACTIVE] = "#ffffff"
 +
}
 +
widget_class "*XfdesktopIconView*" style "xfdesktop-icon-view"
 +
</nowiki>}}
  
Would show all partitions with the exception of sda1 and sda2 on your desktop. Notice, if you are using udisk2 the above will not work, due to the UDISKS_PRESENTATION_HIDE no longer being supported, instead you must use UDISKS_IGNORE as follows
+
==== Remove desktop icons ====
  
KERNEL=="sda1", ENV{UDISKS_IGNORE}="1"
+
Issue the following command:
KERNEL=="sda2", ENV{UDISKS_IGNORE}="1"
 
  
==== Remove Thunar Options from Right-click ====
+
  $ xfconf-query -c xfce4-desktop -v --create -p /desktop-icons/style -t int -s 0
  xfconf-query -c xfce4-desktop -v --create -p /desktop-icons/style -t int -s 0
 
  
==== Kill Window Shortcut ====
+
To reinstate icons on the desktop, issue the same command with a value of 2.
Xfce does not support the ''kill window'' shortcut directly, but you can add one with a simple script. Ensure you have the '''xorg-xkill''' package installed.
 
  
Create a script in {{ic|~/.config/xfce4/killwindow.sh}} with this content and make it executable (you can use {{ic|chmod 755 killwindow.sh}}).
+
==== One wallpaper across multihead ====
  
xkill -id "`xprop -root -notype | sed -n '/^_NET_ACTIVE_WINDOW/ s/^.*# *\|\,.*$//g p'`"
+
Open {{ic|xfce4-settings-editor}} and create a new property with the  following settings:
  
Now associate a shortcut using {{ic|Settings -> Keyboard}} to that script.
+
Property: /backdrop/screen0/xinerama-stretch
 +
Type: Boolean
 +
Value: TRUE|1|Enabled
  
=== XFWM4 ===
+
==== Kill window shortcut ====
==== Enabling the Compositor ====
 
Xfce comes with a builtin compositor adding the option for fancy window effects, shadows and transparency and so on. It can be enabled in the Window Manager Tweaks and works on the fly. No additional settings are needed in your {{ic|/etc/xorg.conf}}. To enable and adjust settings, go to:
 
  
Menu  -->  Settings  -->  Window Manager Tweaks
+
Xfce does not have a shortcut to kill a window, for example when a program freezes.
  
{{Tip|The built-in compositor for Xfwm (the Xfce window manager) often causes video tearing in applications. If you wish for a lightweight compositor with some minimal effects, consider using [[Compton]].}}
+
With {{Pkg|xorg-xkill}}, use {{ic|xkill}} to interactively kill a window. For the currently active window, use {{Pkg|xdotool}}:
  
==== Disable window roll-up ====
+
  $ xdotool getwindowfocus windowkill
  xfconf-query -c xfwm4 -p /general/mousewheel_rollup -s false
 
  
==== Toggle Automatic Tiling of Windows at Edge of Screen ====
+
Alternatively:
XFWM4 has the ability to "tile" a window automatically when it is moved to the edge of the screen by resizing it to fill the top half of the screen. (The official XFCE website says this feature is disabled by default in XFCE 4.10, but it seems to be enabled by default on Arch Linux.) This behavior can be enabled or disabled in {{ic|Window Manager Tweaks --> Accessibility --> Automatically tile windows when moving toward the screen edge}}, or:
 
  
  xfconf-query -c xfwm4 -p /general/tile_on_move -s false  # To disable
+
  $ sh -c "xkill -id $(xprop -root -notype | sed -n '/^_NET_ACTIVE_WINDOW/ s/^.*# *\|\,.*$//g p')"
xfconf-query -c xfwm4 -p /general/tile_on_move -s true  # To enable
 
  
=== Settings Manager Commands ===
+
To add the shortcut, use ''Settings > Keyboard'' or an application like {{pkg|xbindkeys}}.
There is no official documentation for the commands executed. One must look at {{ic|.desktop}} files {{ic|/usr/share/applications/}} folder. For the people who like to know exactly what is happening, here is a handy list to save the effort:
 
  
xfce4-accessibility-settings
+
=== Session ===
xfce4-power-manager-settings
 
xfce4-settings-editor
 
xfdesktop-settings
 
xfce4-display-settings
 
xfce4-keyboard-settings
 
xfce4-mouse-settings
 
xfce4-session-settings
 
xfce4-settings-manager
 
xfce4-appearance-settings
 
xfwm4-settings
 
xfwm4-tweaks-settings
 
xfwm4-workspace-settings
 
orage -p
 
  
To review all the available setting manager commands run the following in a terminal:
+
==== Autostart ====
  
$ grep '^Exec=' /usr/share/applications/xfce*settings* | sed -e 's_^.*=_ _'
+
To launch custom applications when Xfce starts up, click the ''Applications Menu > Settings > Settings Manager'' and then choose the ''Session and Startup'' option and click the tab ''Application Autostart''.
 +
You will see a list of programs that get launched on startup. To add an entry, click the ''Add'' button and fill out the form, specifying the path to an executable you want to run.
  
===Session===
+
Autostart applications are stored as ''.desktop'' files in ''~/.config/autostart/''.
====Custom Startup Applications====
 
  
=====Via the Settings Menu=====
+
Alternatively, add the commands you wish to run (including setting environment variables) to [[xinitrc]] (or [[xprofile]] when a [[display manager]] is being used).
  
To launch custom applications when Xfce starts up, click the Applications Menu -> Settings -> Settings Manager and then choose the "Session and Startup" option and click the tab "Application Autostart".
+
{{Tip|Sometimes it might be useful to '''delay the startup of an application'''. Note that specifying under ''Application Autostart'' a command such as {{ic|sleep 3 && ''command''}}  does not work; a workaround is to use the syntax {{ic|sh -c "sleep 3 && ''command''"}}
You'll see a list of programs that get launched on startup. To add an entry, click the "Add" button and fill out the form, specifying the path to an executable you want to run.
+
}}
  
=====Startup Script=====
+
==== Lock the screen ====
 +
''xflock4'' is the reference Bash script which is used to lock an Xfce session . It tries consecutively four screen lockers or exits with return code 1 if it fails to find any. Therefore, for ''xflock4'' to succeed, either {{Pkg|xscreensaver}}, {{Pkg|gnome-screensaver}}, {{Pkg|slock}} or {{Pkg|xlockmore}} needs to be installed.
  
Alternatively you can use this method, to run a command line script to launch your applications. This includes getting necessary environment variables into the GUI runtime.
+
The [[List of applications/Security#Screen lockers]] contains a short description of these four screen lockers together with other popular applications.  
  
* Copy the file {{ic|/etc/xdg/xfce4/xinitrc}} to {{ic|~/.config/xfce4/}}
+
In particular, {{Pkg|light-locker}} integrates well with {{Pkg|xfce4-power-manager}}: once installed, Xfce Power Manager's setting gains an additional ''Security'' tab to configure ''light-locker'' and the existing ''Lock screen when system is going for sleep'' setting is relocated under this tab. It is then possible to set in this GUI whether the session should be locked upon screensaver activity or whenever the system goes to sleep.
* Edit this file. For example, you can add something like this somehwere in the middle:
 
source $HOME/.bashrc
 
# start rxvt-unicode server
 
urxvtd -q -o -f
 
  
====Lock the screen====
+
To have ''xflock4'' '''run ''light-locker'' or any custom session locker''' not among the four cited above, some steps are required.
To lock an Xfce4 session (through {{ic|xflock4}}) one of {{Pkg|xscreensaver}}, {{Pkg|gnome-screensaver}} or {{Pkg|xlockmore}} packages needs to be installed.
+
The latest 4.13 version of {{pkg|xfce4-session}}, not available in the official repositories yet, eases the integration of custom screen lockers with ''xfclock4'' (see the [https://git.xfce.org/xfce/xfce4-session/tree/scripts/xflock4 latest xflock4 on git.xfce.org]) by checking first for the {{ic|LockCommand}} set in the session's xfconf channel.
 +
Therefore to use a custom locker with ''xflock4'' one can follow the two steps below:
 +
# Use the command line below to set {{ic|LockCommand}}, here for example to use ''light-locker'': {{bc|$ xfconf-query -c xfce4-session -p /general/LockCommand -s "'''light-locker-command --lock'''" --create -t string}}The command inside the quotes can be adapted accordingly for other screen lockers.
 +
# Enhance the ''xflock4'' script with either one of the following methods:
 +
## Replace manually {{ic|/usr/bin/xflock4}} with the latest version of the script, so that it calls the command specified in {{ic|LockCommand}}.
 +
## Install {{aur|xfce4-session-git}} in order to replace the official repository package with the updated 4.13 version which takes into account {{ic|LockCommand}}.
  
====Switch between users====
+
The '''panel lock button''' in the ''Action Buttons'' panel simply executes {{ic|/usr/bin/xflock4}}. It should work as expected as long as ''xflock4'' is functioning i.e. one of the native lockers is installed or a custom locker is configured to integrate with it as proposed above.
Xfce4 allows this behavior under the 'action buttons' menu item. Currently, both [[gdm]] and [[Lightdm#User switching under xfce4|lightdm]] provide this functionality.
 
  
==== Manually Modifying XML settings ====
+
==== Suspend ====
It may be useful, especially when upgrading, to manually edit .xml files in the {{ic|~/.config/xfce4/xfconf/}} folder. For application keyboard shortcuts for example, the file is {{ic|~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml}}. It is faster to copy and paste the XML keys that you want rather than using the GUI.
+
Whenever asked to suspend, Xfce executes the {{man|1|xfce4-session-logout}} command with the {{ic|suspend}} option:
  
===Removable Devices===
+
$ xfce4-session-logout --suspend
If you want an icon appearing on your desktop and in Thunar when you plug in external devices, make sure {{Pkg|gvfs}} is installed. You could also need to install {{Pkg|gvfs-afc}} (read [https://bbs.archlinux.org/viewtopic.php?pid=889018 this discussion]). It is also a good idea to install {{Pkg|thunar-volman}} (already included in the {{Grp|xfce4}} base group). Additionally, [[udisks]] and a udisks wrapper are recommended if you want to automount optical and external drives easily.
 
  
===Look and Feel===
+
Whether or not the session is systematically locked on ''suspend'' can be configured through the xfconf properties or from the GUI.
====Add themes to XFCE====
 
1. Go to [http://www.xfce-look.org www.xfce-look.org] and click "Themes" in the left navbar. Look around for a theme you want and click "Download".
 
  
2. Go to the directory where you downloaded the tarball/file and extract it using Squeeze/Xarchiver/CLI.
+
To control this state using the CLI: there are two settings that are used, {{ic|LockScreen}} and {{ic|lock-screen-suspend-hibernate}}, in respectively the session and the power manager xfconf channels.
 +
To prevent locking on suspend, turn them to {{ic|false}}:
 +
$ xfconf-query -c xfce4-session -p /shutdown/LockScreen -s '''false'''
 +
$ xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/lock-screen-suspend-hibernate -s '''false'''
 +
Similarly, turn them to {{ic|true}} to lock the session on suspend.
  
3. Move the extracted folder to {{ic|/usr/share/themes}} (for all users) or {{ic|~/.themes}} (for just you). Inside {{ic|/usr/share/themes/abc}}, there is a folder that you create called xfwm4 that will contain whatever files that is included with that theme.
+
The setting can also be controlled from the GUI: open the ''Session and Startup'' application and turn the flag ''Advanced > Lock screen before sleep'' on or off.
  
4. GTK theme is available here:
+
Whenever the suspend keyboard button is pressed, it can be handled by either Xfce's power manager or by ''systemd-logind''. To give precedence to logind, the following xfconf setting must be set to {{ic|true}}:
Menu --> Settings --> Appearance
 
You select your xfwm theme in:
 
Menu --> Settings --> Window Manager
 
  
==== Cursors ====
+
$ xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/logind-handle-suspend-key -n -t bool -s '''true'''
Main article: [[X11 Cursors]]
 
  
If you have alternative X cursor themes installed, Xfce can find them with:
+
{{Note|To check how ''systemd-logind'' handles events whenever it has precedence over Xfce, check {{man|5|logind.conf}}}}
Menu --> Settings --> Mouse --> Theme
 
  
==== Icons ====
+
==== Disable saved sessions ====
# First find and download your desired icon pack. Recommended places to download icons from are [http://www.customize.org Customize.org], [http://opendesktop.org Opendesktop.org] and [http://xfce-look.org/ Xfce-look.org]; the [[AUR]] provides several PKGBUILDs for icon packs.
 
# Go to the directory where you downloaded the icon pack and extract it. Example {{ic|tar -xzf /home/user/downloads/icon-pack.tar.gz}}.
 
# Move the extracted folder containing the icons to {{ic|~/.icons}} (if only you want to use the icons) or to {{ic|/usr/share/icons}} (if you want all users on the system to make use of the icons), and in the lattter case consider creating a [[PKGBUILD]] for that.
 
# Optional: run {{ic|gtk-update-icon-cache -f -t ~/.icons/<theme_name>}} to update icon cache
 
# Switch your icons by going to:
 
Menu --> Settings --> Appearance --> Icons
 
  
When you have icon theme problems, it is also recommended to install the {{Pkg|hicolor-icon-theme}} package if it was not already installed.
+
Per user, saved sessions can be disabled by executing the following:
 +
$ xfconf-query -c xfce4-session -p /general/SaveOnExit -s false
 +
Then navigate to ''Applications > Settings > Session and Startup > Sessions'' and press the ''Clear saved sessions'' button to remove all previously saved sessions.
  
==== Fonts ====
+
{{Tip|If the command above does not change the setting persistently, use the following command instead: {{ic|xfconf-query -c xfce4-session -p /general/SaveOnExit -n -t bool -s false}}}}
If you find the standard fonts rather thick and or slightly out of focus open Settings>Appearence click on the Fonts tab and under Hinting: change to Full
 
  
You could also try using a custom DPI setting.
+
Alternatively, Xfce [https://wiki.xfce.org/howto/kiosk_mode kiosk mode] can be used to disable the saving of sessions systemwide. To disable sessions, create or edit the file {{ic|/etc/xdg/xfce4/kiosk/kioskrc}} and add the following:
  
=== Sound ===
+
[xfce4-session]
 +
SaveSession=NONE
  
==== Configuring xfce4-mixer ====
+
If kiosk mode is not working, the user can set read only permissions for the sessions directory:
  
{{Pkg|xfce4-mixer}} is the GUI mixer app / panel plugin made by the Xfce team. It is part of the xfce4 group, so you probably already have it installed. Xfce 4.6 uses {{Pkg|gstreamer}} as the backend to control volume, so first you have to make gstreamer cooperate with xfce4-mixer. One or more of the gstreamer plugin packages listed as optional dependencies to xfce4-mixer must be installed. Without one of these required plugins packages, the following error arises when clicking on the mixer panel item.
+
$ rm ~/.cache/sessions/* && chmod 500 ~/.cache/sessions
  
  GStreamer was unable to detect any sound devices. Some sound system specific GStreamer packages may be missing. It may also be a permissions problem.
+
This will prevent Xfce from saving any sessions despite any configuration that specifies otherwise.
  
(It is probably not a permissions problem. It is no longer required to add audio users to the "audio" group.) Which plugins are needed depends on the hardware. Most people should be fine with {{Pkg|gstreamer0.10-base-plugins}} which can be [[pacman|installed]] from  [[Official Repositories]].
+
==== Use a different window manager ====
  
If the xfce4-mixer panel item was already running before one of the plugins packages was installed, logout and login to see if it worked, or just remove the mixer plugin from the panel and add it again. If that does not work, you might need more or different gstreamer plugins. Try to [[pacman|install]] package  {{pkg|gstreamer0.10-good-plugins}} or {{pkg|gstreamer0.10-bad-plugins}}.
+
{{Note|For the changes to take effect, you will need to clear the saved sessions and ensure that session saving is disabled when logging out for the first time. Once the window manager of choice is running, session saving can be enabled again.}}
  
If you had to change the soundcard in the audio mixer, then you should log out and back in to hear sound.
+
The files specifying the default window manager are found in the following locations:
 +
*{{ic|~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-session.xml}} - per user
 +
*{{ic|/etc/xdg/xfce4/xfconf/xfce-perchannel-xml/xfce4-session.xml}} - systemwide
  
For further details, for example how to set the default sound card, see [[Advanced Linux Sound Architecture]]. Alternatively you can use [[PulseAudio]] together with {{Pkg|pavucontrol}}.
+
The default window manager for the user can be set easily using ''xfconf-query'':
 +
$ xfconf-query -c xfce4-session -p /sessions/Failsafe/Client0_Command -t string -sa '''wm_name'''
  
==== Xfce4-mixer and OSS4 ====
+
If you want to start the window manager with command line options, see the command below:
 +
$ xfconf-query -c xfce4-session -p /sessions/Failsafe/Client0_Command -t string -t string -s '''wm_name''' -s '''--wm-option'''
 +
If you need more command line options, simply add more {{ic|-t string}} and {{ic|-s '''--wm-option'''}} arguments to the command.
  
If you tried the above section to get {{Pkg|xfce4-mixer}} to work and it does not work at all, then you may have to compile {{pkg|gstreamer0.10-good-plugins}} yourself. Download the PKGBUILD and other files needed from ABS or [https://projects.archlinux.org/svntogit/packages.git/tree/gstreamer0.10-good/repos here], edit the PKGBUILD, add --enable-oss.  
+
If you want to change the default window manager systemwide, edit the file specified above manually, changing ''xfwm4'' to the preferred window manager and adding more {{ic|1=<value type="string" value="'''--wm-option'''"/>}} lines for extra command line options if needed.
  
  ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var \
+
You can also change the window manager by autostarting {{ic|'''wm_name''' --replace}} using the autostart facility or by running {{ic|'''wm_name''' --replace &}} in a terminal and making sure the session is saved on logout. Be aware though that this method does not truly change the default manager, it merely replaces it at login. Note that if you are using the autostart facility, you should disable saved sessions as this could lead to the new window manager being started twice after the default window manager.
    '''--enable-oss \'''
 
    --disable-static --enable-experimental \
 
    --disable-schemas-install \
 
    --disable-hal \
 
    --with-package-name="GStreamer Good Plugins (Archlinux)" \
 
    --with-package-origin="https://www.archlinux.org/"
 
  
and then run makepkg -i.
+
=== Theming ===
  
  makepkg -i
+
XFCE themes are available at [http://www.xfce-look.org xfce-look.org]. ''Xfwm'' themes are stored in {{ic|/usr/share/themes/xfce4}}, and set in ''Settings > Window Manager''. [[GTK+]] themes are set in ''Settings > Appearance''.
  
Still not working? Try this package in AUR {{AUR|gstreamer0.10-good-plugins-ossv4}}, modify the pkgver to the newest in the PKGBUILD, and it should work.
+

==== Keyboard Volume Buttons  ====
+
=== Sound ===
  
Go to
+
==== Keyboard volume buttons ====
Settings --> Keyboard
 
Click the "Application Shortcuts" tab and add click the "Add" button. Add the following by entering the command, then pressing the corresponding button at the next window:
 
  
===== ALSA =====
+
{{Pkg|xfce4-pulseaudio-plugin}} provides a panel applet which has support for keyboard volume control and volume notifications. As an alternative, you can install {{AUR|xfce4-volumed-pulse}}, which also provides keybinding and notification control, but without an icon sitting in the panel. This is handy, for example, when using {{AUR|pasystray}} at the same time for a finer control.
For the raise volume button:
 
amixer set Master 5%+
 
For the lower volume button:
 
amixer set Master 5%-
 
For the mute button:
 
amixer set Master toggle
 
  
You can also run these commands to set the above commands to the standard XF86Audio keys:
+
Alternatively, [https://git.xfce.org/apps/xfce4-mixer/ xfce4-mixer] also provides a panel applet and keyboard shortcuts which supports Alsa as well. Note however, that it is based on a feature of GStreamer 0.10 which has been abandoned in 1.0.
xfconf-query -c xfce4-keyboard-shortcuts -p /commands/custom/XF86AudioRaiseVolume -n -t string -s "amixer set Master 5%+ unmute"
 
xfconf-query -c xfce4-keyboard-shortcuts -p /commands/custom/XF86AudioLowerVolume -n -t string -s "amixer set Master 5%- unmute"
 
xfconf-query -c xfce4-keyboard-shortcuts -p /commands/custom/XF86AudioMute -n -t string -s "amixer set Master toggle"
 
  
If {{ic|amixer set Master toggle}} does not work, try the PCM channel ({{ic|amixer set PCM toggle}}) instead.
+
For non desktop environment specific alternatives, see [[List of applications#Volume managers]].
  
The channel must have a "mute" option for the toggle command to work. To check whether or not your Master channel supports toggling mute, run {{ic|alsamixer}} in a terminal and look for the double M's (MM) under the Master channel. If they are not present, then it does not support the mute option. If, for example, you had to change the toggle button to use the PCM channel, make sure to also set the PCM channel as the Mixer Track under Xfce Mixer properties.
+
===== Shortcuts =====
  
===== OSS =====
+
If you are not using an applet or daemon that controls the volume keys, you can map volume control commands to your volume keys manually using Xfce's keyboard settings. For the sound system you are using, see the sections linked to below for the appropriate commands.
Use one of these scripts: http://www.opensound.com/wiki/index.php/Tips_And_Tricks#Using_multimedia_keys_with_OSS
+
*ALSA: see [[Advanced Linux Sound Architecture#Keyboard volume control]].
 +
*PulseAudio: see [[PulseAudio#Keyboard volume control]]
 +
*OSS: see [[OSS#Using multimedia keys with OSS]].
  
If using ossvol (recommended), add:
+
=== Keyboard Shortcuts ===
ossvol -i 1
 
for the volume up button
 
ossvol -d 1
 
for the volume down button
 
ossvol -t
 
for the mute/unmute button
 
  
===== PulseAudio =====
+
Keyboard shortcuts are defined in two places: ''Settings > Window Manager > Keyboard'', and ''Settings > Keyboard > Shortcuts''.
For the raise volume button:
 
pactl set-sink-mute 0 false ; pactl set-sink-volume 0 +1%
 
For the lower volume button:
 
pactl set-sink-mute 0 false ; pactl -- set-sink-volume 0 -1%
 
For the mute button:
 
pactl set-sink-mute 0 toggle
 
  
These settings assume the device you want to control has index 0.
+
=== Polkit Authentication Agent ===
Use {{ic|pactl list sinks short}} to list sinks.
 
  
===== Xfce4-volumed =====
+
The {{Pkg|polkit-gnome}} agent will be installed along with {{Pkg|xfce4-session}} and autostarted automatically; no user intervention is required. For more information, see [[Polkit#Authentication agents]].
  
[https://aur.archlinux.org/packages.php?ID=31693 xfce4-volumed] daemon from the [[AUR]] automatically maps volume keys of your keyboard to Xfce-mixer. Additionally you get OSD through Xfce4-notifyd when changing volume. Xfce4-volumed does not need any configuration and is started automatically with Xfce.
+
A third party polkit authentication agent for Xfce is also available, see {{AUR|xfce-polkit}} or {{AUR|xfce-polkit-git}}.
  
{{accuracy|reason=There should be a short explanation of what this does and why it fixes the problem (bug?).}}
+
=== Display blanking ===
 +
Some programs that are commonly used with Xfce will control monitor blanking and [[DPMS]] (monitor powersaving) settings. They are discussed below.
  
If you use pulseaudio and xfce4-volumed unmute does not work, try this:
+
;Xfce Power Manager
 +
''Xfce Power Manager'' controls blanking and DPMS settings. These settings can be configured in the ''Power Manager'' GUI within the ''Display'' tab.
  
$ xfconf-query -c xfce4-mixer -p /active-card -s `xfconf-query -c xfce4-mixer -p /sound-card`
+
Note that when ''Display power management'' is turned off, DPMS is fully disabled, it does not mean that ''Power Manager'' will simply stop controlling DPMS. It does not disable screen blanking either. To disable both blanking and DPMS, right click on the power manager system tray icon or left click on the panel applet and make sure that the option labelled ''Presentation mode'' is ticked.
  
===== Volumeicon =====
+
;XScreenSaver
 +
If {{pkg|xscreensaver}} is installed and runs alongside Xfce Power Manager, it may not be clear which application is in control of blanking and DPMS as both are competing for control of the same settings. Therefore, in a situation where it is important that the monitor not be blanked (when watching a video for instance), it is advisable to disable blanking and DPMS through both applications. To know more about ''XScreenSaver'' options, see [[XScreenSaver#DPMS and blanking settings]].
  
{{pkg|volumeicon}} is an alternative to xfce4-volumed in the community repo also handling keybindings and notifications through {{pkg|xfce4-notifyd}}.
+
;xset
 +
If neither of the above applications are running, then blanking and DPMS settings can be controlled using the ''xset'' command, see [[DPMS#Modifying DPMS and screensaver settings using xset]].
  
===== Extra keyboard keys =====
+
{{Note|1=There are some issues associated with blanking and resuming from blanking in some configurations. See [https://bbs.archlinux.org/viewtopic.php?id=194313&p=2][https://bugzilla.xfce.org/show_bug.cgi?id=11107].}}
If you are coming from another distro, you may be interested in enabling extra keys on your keyboard, see [[Extra Keyboard Keys]].
 
  
==== Adding startup/boot sound ====
+
== Tips and tricks ==
  
Arch does not have a built-in startup sound configuration tool, but there is a workaround by adding the following command to your Application Autostart settings:
+
=== Hide partitions from thunar and xfdesktop ===
  
aplay /boot/startupsound.wav
+
If your installation partitions are shown as mounted devices on the desktop and in Thunar, try to install {{Pkg|gvfs}}. See [[Udisks#Hide selected partitions]] for more advanced configuration options.
  
The file location and filename can be whatever you want, but naming it descriptively and putting it in /boot keeps things tidy.
+
=== Screenshots ===
  
=== xdg-open integration (Preferred Applications) ===
+
Xfce has its own screenshot tool, {{pkg|xfce4-screenshooter}}. It is part of the {{grp|xfce4-goodies}} group.
  
Most applications rely on [[xdg-open]] for opening a preferred application for a given file or URL.
+
Go to ''Applications > Settings > Keyboard'', ''Application Shortcuts''. Add the {{ic|xfce4-screenshooter -f}} (or {{ic|-w}} for the active window) command to use the {{ic|Print}} key in order to take fullscreen screenshots. See screenshooter's man page for other optional arguments.
  
In order for xdg-open and xdg-settings to detect and integrate with the XFCE desktop environment correctly, you need to [[pacman|install]] the {{Pkg|xorg-xprop}} package.
+
Alternatively, an independent screenshot program like [[Taking a screenshot#scrot|scrot]] can be used.
  
If you do not do that, your preferred applications preferences (set by exo-preferred-applications) will not be obeyed.
+
=== Disable Terminal F1 and F11 shortcuts ===
Installing the package and allowing ''xdg-open'' to detect that you are running XFCE makes it forward all calls to ''exo-open'' instead, which correctly uses all your preferred applications preferences.
 
  
To make sure xdg-open integration is working correctly, ask ''xdg-settings'' for the default web browser and see what the result is:
+
The xfce terminal binds F1 and F11 to help and fullscreen, respectively, which can make using programs like htop difficult. To disable those shortcuts, create or edit its configuration file, then log out and log back in. F10 can disabled in the Preferences menu.
  
# xdg-settings get default-web-browser
+
{{hc|~/.config/xfce4/terminal/accels.scm|
 +
(gtk_accel_path "<Actions>/terminal-window/fullscreen" "")
 +
(gtk_accel_path "<Actions>/terminal-window/contents" "")
 +
}}
  
If it replies with:
+
=== Terminal color themes or palettes ===
 
 
xdg-settings: unknown desktop environment
 
 
 
it means that it has failed to detect XFCE as your desktop environment, which is likely due to a missing {{Pkg|xorg-xprop}} package.
 
  
=== Screenshots ===
+
Terminal color themes or palettes can be changed in GUI under Appearance tab in Preferences. These are the colors that are available to most console applications like [[Emacs]], [[Vi]] and so on. Their settings are stored individually for each system user in {{ic|~/.config/xfce4/terminal/terminalrc}} file. There are also so many other themes to choose from. Check forum thread [https://bbs.archlinux.org/viewtopic.php?id=51818 Terminal Colour Scheme Screenshots] for hundreds of available choices and themes.
  
XFCE has its own screenshot tool, {{pkg|xfce4-screenshooter}}. It is part of the {{grp|xfce4-goodies}} group.
+
==== Changing default color theme ====
  
==== Print Screen key ====
+
Xfce's {{ic|extra/terminal}} package comes with a darker colour palette. To change this, append the following in your terminalrc file for a lighter color theme, that is always visible in darker Terminal backgrounds.
  
Go to:
+
{{hc|~/.config/xfce4/terminal/terminalrc|2=

+
==== Terminal tango color theme ====
  
Add the "xfce4-screenshooter -f" command to use the "PrintScreen" key in order to take fullscreen screenshots. See screenshooter's man page for other optional arguments.
 
 
Alternatively, an independent screenshot program like [[Taking a Screenshot#scrot|scrot]] can be used.
 
 
===Terminal color themes or pallets===
 
Terminal color themes or pallets can be changed in GUI under Appearance tab in Preferences. These are the colors that are available to most console applications like [[Emacs]], [[Vi]] and so on. Their settings are stored individually for each system user in {{ic|~/.config/xfce4/terminal/terminalrc}} file. There are also so many other themes to choose from. Check forums post [[https://bbs.archlinux.org/viewtopic.php?pid=1194644|Terminal Colour Scheme Screenshots]] for hundreds of available choices and themes.
 
 
====Changing default color theme====
 
XFCE's {{ic|extra/terminal}} package comes with a darker color palette and colored text looks pretty horrid in default black background impeding user readability. Append the following in your terminalrc file for a lighter color theme, that is always visible in darker Terminal backgrounds.

=== Colour management ===
 
=== Colour management ===
xfce4-settings-manager does not yet have any colour management / calibration settings, nor is there any specific XFCE program to characterise your monitor.
 
  
==== Loading a profile ====
+
Xfce has no native support for colour management. [https://bugzilla.xfce.org/show_bug.cgi?id=8559] See [[ICC profiles]] for alternatives.
If you wish to '''load an icc profile''' (that you have previously created or downloaded) to calibrate your display on startup, you can download {{AUR|xcalib}} from [[AUR]], then open the XFCE4 Settings Manager, click Session and Startup icon, the Autostart tab, and add a new entry where the command is {{ic|/usr/bin/xcalib /path/to/your/profile.icc}}. You still need to tell your applications, which display profile should be used to have the displayed images colour managed.
 
  
Another option is dispwin. Dispwin not only calibrates the display, but also sets the _ICC_PROFILE atom in X so that some applications can use a "system" display profile instead of requiring the user to set the display profile manually (GIMP, Inkscape, darktable, UFRaw, etc.).
+
=== Multiple monitors ===
  
See [[ICC Profiles#Loading ICC Profiles]] for more information.
+
Xfce has support for multiple monitors. Settings can be configured in the ''Applications > Settings > Display'' dialog. For more information, see the [http://docs.xfce.org/xfce/xfce4-settings/display display] article from the Xfce documentation.
  
==== Creating a profile ====
+
=== SSH agents ===
  
If you wish to '''create an icc profile''' for your display (ie. characterising/profiling, e.g. with the ColorHug, or some other colorimeter, or a spectrophotometer, or "by eye"), the simplest option may be to install {{AUR|dispcalGUI}} from [[AUR]].
+
By default Xfce 4.10 will try to load gpg-agent or ssh-agent in that order during session initialization. To disable this, create an xfconf key using the following command:
  
Another option is to install {{pkg|gnome-settings-daemon}} and {{pkg|gnome-color-manager}} (available in extra). In order to start the calibration from the command line, first do  {{ic|/usr/lib/gnome-settings-daemon/gnome-settings-daemon &}} (note: this might change your keyboard layout and who knows what else, so probably good to do it on a throwaway account), then {{ic|colormgr get-devices}} and look for the "Device ID" line of your monitor. If this is e.g. "xrandr-Lenovo Group Limited", you start calibration with the command {{ic|gcm-calibrate --device "xrandr-Lenovo Group Limited"}}.
+
xfconf-query -c xfce4-session -p /startup/ssh-agent/enabled -n -t bool -s false
{{Note|1=The reason you need gnome-settings-daemon running is because XFCE does not yet have a session component for colord: https://bugzilla.xfce.org/show_bug.cgi?id=8559}}
 
  
See [[ICC Profiles]] for more information.

To force using ssh-agent even if gpg-agent is installed, run the following instead:
  
=== Multiple Monitors ===
+
xfconf-query -c xfce4-session -p /startup/ssh-agent/type -n -t string -s ssh-agent
If you have configured X.org so that your display spans multiple monitors, usually when you login to an '''XFCE''' session, it will appear as if your monitors are simple clones of one another. You can use an '''xrandr''' tool to tweak your setup but if this is not called at an appropriate time in the startup sequence, some functionality may be lost with parts of your display being inaccessible to the mouse pointer.
 
  
A better way is to configure XFCE to match your desired display arrangement. However, at present (xfce-settings 4.10), there is no tool available to assist with configuring multiple monitors directly.  
+
To use [[GNOME Keyring]], simply tick the checkbox ''Launch GNOME services on startup'' in the ''Advanced'' tab of ''Session and Startup'' in Xfce's settings. This will also disable gpg-agent and ssh-agent.
  
* The ''Settings -> Display'' tool does allow configuration of screen resolution, rotation and enabling individual monitors; '''warning''': ''using this tool to adjust display settings will reset or lose settings made manually for properties not explicitly offered as buttons in the tool (see below)''.
+
Source: http://docs.xfce.org/xfce/xfce4-session/advanced
* The ''Settings -> Settings Editor'' allows manipulation of all configuration items in particular the ''displays'' settings which are saved in the file '''displays.xml''' below
 
~/.config/xfce4/xfconf/xfce-perchannel-xml
 
* Alternatively, the ''displays.xml'' can be edited using your favourite editor.
 
  
The main requirement for multiple monitors is their arrangement relative to one another. This can be controlled by setting the '''Position''' properties ('''X''' and '''Y''') to suit; an ''(x,y)'' position of ''0,0'' corresponds to the ''top, left'' position of the monitor array. This is the default position for all monitors and if several monitors are enabled they will appear as a cloned display area extending from this point.
+
=== Scroll a background window without shifting focus on it ===
  
To extend the display area correctly across both monitors:
+
Go to ''Main Menu > Settings > Window Manager Tweaks > Accessibility'' tab.
 +
Uncheck ''Raise windows when any mouse button is pressed''.
  
* for side-by-side monitors, set the '''X''' property of the rightmost monitor to equal the width of the left-most monitor
+
=== Mouse button modifier ===
* for above-and-below monitors, set the '''Y''' property of the bottom monitor to equal the height of the upper monitor
 
* for other arrangements, set the '''X''' and '''Y''' properties of each monitor to correspond to your layout
 
  
Measurements are in ''pixels''. As an example, a pair of monitors with nominal dimensions of ''1920x1080'' which are rotated by 90 and placed side-by-side can be configured with a ''displays.xml'' like this:
+
By default, the mouse button modifier in Xfce is set to {{ic|Alt}}. This can be changed with ''xfconf-query''. For instance, the following command will set the {{ic|Super}} key as the mouse button modifier:
  
  <channel name="displays" version="1.0">
+
  $ xfconf-query -c xfwm4 -p /general/easy_click -n -t string -s "Super"
  <property name="Default" type="empty">
+
 
    <property name="VGA-1" type="string" value="Idek Iiyama 23&quot;">
+
Strictly speaking, using multiple modifiers is not supported. However, as a workaround, multiple modifiers can be specified if the key names are separated with {{ic|><}}. For instance, to set {{ic|Ctrl+Alt}} as the mouse button modifier, you can use the following command:
      <property name="Active" type="bool" value="true"/>
+
 
      <property name="Resolution" type="string" value="1920x1080"/>
+
$ xfconf-query -c xfwm4 -p /general/easy_click -n -t string -s "Ctrl><Alt"
      <property name="RefreshRate" type="double" value="60.000000"/>
+
 
      <property name="Rotation" type="int" value="90"/>
+
=== Set the two fingers click to middle click for a touchpad ===
      <property name="Reflection" type="string" value="0"/>
+
 
      <property name="Primary" type="bool" value="false"/>
+
{{Style|Convoluted way of simply configuring [[Touchpad Synaptics]]}}
       <property name="Position" type="empty">
+
 
         <property name="X" type="int" value="0"/>
+
If you want the 2 finger click on the touchpad to do a middle click, create or edit the following file:
         <property name="Y" type="int" value="0"/>
+
 
      </property>
+
{{hc|~/.config/xfce4/xfconf/xfce-perchannel-xml/pointers.xml|<nowiki>
    </property>
+
<channel name="pointers" version="1.0">
    <property name="DVI-0" type="string" value="Digital display">
+
  <property name="SynPS2_Synaptics_TouchPad" type="empty">
      <property name="Active" type="bool" value="true"/>
+
    <property name="Properties" type="empty">
      <property name="Resolution" type="string" value="1920x1080"/>
+
       <property name="Synaptics_Tap_Action" type="array">
      <property name="RefreshRate" type="double" value="60.000000"/>
+
         <value type="int" value="0"/>
      <property name="Rotation" type="int" value="90"/>
+
         <value type="int" value="0"/>
      <property name="Reflection" type="string" value="0"/>
+
        <value type="int" value="0"/>
      <property name="Primary" type="bool" value="false"/>
+
        <value type="int" value="0"/>
      <property name="Position" type="empty">
+
        <value type="int" value="1"/>
         <property name="X" type="int" value="1080"/>
+
         <value type="int" value="2"/>
         <property name="Y" type="int" value="0"/>
+
         <value type="int" value="3"/>
 
       </property>
 
       </property>
 
     </property>
 
     </property>
 
   </property>
 
   </property>
</channel>
+
</channel>
 +
</nowiki>}}
 +
 
 +
The 2 in the array is the middle click.
 +
 
 +
=== Limit the minimum brightness of the brightness-slider ===
 +
Limiting the minimum brightness can be useful for displays which turn off backlight on a brightness level of 0. In {{ic|xfce4-power-manager 1.3.2}} a new hidden option had been introduced to set a minimum brightness value with a xfconf4-property. Add {{ic|brightness-slider-min-level}} as an int property in xfconf4. Adjust the int value to get a suitable minimum brightness level.
 +
 
 +
=== Adding profile pictures ===
 +
To add profile pictures for each user to be displayed in the whisker-menu, simply place a 96x96 PNG file in the respective user's home directory with the name {{ic|.face}}. For example the PNG file {{ic|/home/''bob''/.face}} for user ''bob''.
  
Usually, editing settings in this way requires a logout/login to action them.
+
Image editing programs like [[GIMP]] can be used to convert and scale your favourite images down to 96x96.
  
A new method for configuring multiple monitors will be available in the forthcoming xfce-settings 4.12 release.
+
===  Power manager plugin label ===
  
=== XDG User Directories ===
+
The xfconf option {{ic|show-panel-label}} of type {{ic|int}} controls the label of the power manager, it can be configured for different label formats: it can be set to 0 (no label), 1 (percentage), 2 (remaining time) or 3 (both).
freedesktop.org specifies the "well known" user directories like the desktop folder and the music folder.  See [[Xdg user directories]] for detailed info.
 
  
=== SSH Agents ===
+
It is also accessible through the power manager plugin GUI in ''Properties > Show label''
By default Xfce 4.10 will try to load gpg-agent or ssh-agent in that order during session initialization. To disable this, create an xfconf key using the following command:
+
 
 +
== Troubleshooting ==
 +
 
 +
=== Desktop icons rearrange themselves ===
 +
 
 +
At certain events (such as opening the panel settings dialog) icons on the desktop rearrange themselves. This is because icon positions are determined by files in the {{ic|~/.config/xfce4/desktop/}} directory. Each time a change is made to the desktop (icons are added or removed or change position) a new file is generated in this directory and these files can conflict.
 +
 
 +
To solve the problem, navigate to the directory and delete all the files other than the one which correctly defines the icon positions. You can determine which file defines the correct icon positions by opening it and examining the locations of the icons. The topmost row is defined as {{ic|row 0}} and the leftmost column is defined by {{ic|col 0}}. Therefore an entry of:
 +
 
 +
[Firefox]
 +
row=3
 +
col=0
 +
 
 +
means that the Firefox icon will be located on the 4th row of the leftmost column.
 +
 
 +
=== GTK themes not working with multiple monitors ===
 +
 
 +
{{Expansion|Which configuration tools? What does ''ceasing to work'' mean? Is it that new themes cannot be selected or that themes display incorrectly? Is there a bug report?}}
 +
 
 +
Some configuration tools may corrupt displays.xml, which results in GTK themes under ''Applications Menu > Settings > Appearance'' ceasing to work. To fix the issue, delete {{ic|~/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml}} and reconfigure your screens.
 +
 
 +
=== Icons do not appear in right-click menus ===
 +
 
 +
{{Note|Despite the deprecation of GConf, this method does still work.}}
 +
 
 +
Users may find that icons do not appear when right-clicking options within some applications, including those made with [[Qt]]. This problem only appears to happen within Xfce. Run these two commands:
 +
 
 +
$ gconftool-2 --type boolean --set /desktop/gnome/interface/buttons_have_icons true
 +
$ gconftool-2 --type boolean --set /desktop/gnome/interface/menus_have_icons true
 +
 
 +
=== NVIDIA and xfce4-sensors-plugin ===
 +
 
 +
To detect and use sensors of nvidia gpu you need to install {{Pkg|libxnvctrl}} and then rebuild {{Pkg|xfce4-sensors-plugin}} with [[ABS]]. You also have the option of using {{AUR|xfce4-sensors-plugin-nvidia}} which replaces {{Pkg|xfce4-sensors-plugin}}.
 +
 
 +
=== Panel applets keep being aligned on the left ===
  
xfconf-query -c xfce4-session -p /startup/ssh-agent/enabled -n -t bool -s false
+
Add a separator someplace before the right end and set its "expand" property. [https://forums.linuxmint.com/viewtopic.php?f=110&t=155602}]
  
To force using ssh-agent even if gpg-agent is installed, run the following instead:
+
=== Preferred Applications preferences have no effect ===
  
xfconf-query -c xfce4-session -p /startup/ssh-agent/type -n -t string -s ssh-agent
+
Most applications rely on [[xdg-open]] for opening a preferred application for a given file or URL.
  
To use [[GNOME Keyring]], simply tick the checkbox ''Launch GNOME services on startup'' in the ''Advanced'' tab of ''Session Manager'' in Xfce's settings. This will also disable gpg-agent and ssh-agent.
+
In order for xdg-open and xdg-settings to detect and integrate with the Xfce desktop environment correctly, you need to [[install]] the {{Pkg|xorg-xprop}} package.
  
Source: http://docs.xfce.org/xfce/xfce4-session/advanced
+
If you do not do that, your preferred applications preferences (set by exo-preferred-applications) will not be obeyed.
 +
Installing the package and allowing ''xdg-open'' to detect that you are running Xfce makes it forward all calls to ''exo-open'' instead, which correctly uses all your preferred applications preferences.
  
== Troubleshooting ==
+
To make sure xdg-open integration is working correctly, ask ''xdg-settings'' for the default web browser and see what the result is:
=== xfce4-power-manager ===
 
Power-related [[Wikipedia:Advanced Configuration and Power Interface|ACPI]] events can be configured using [[systemd]] via options from {{ic|/etc/systemd/logind.conf}} to give control to xfce4-power-manager.
 
  
{{hc|/etc/systemd/logind.conf|2=
+
# xdg-settings get default-web-browser
HandlePowerKey=ignore
 
HandleSuspendKey=ignore
 
HandleHibernateKey=ignore
 
HandleLidSwitch=ignore}}
 
  
This also solves the problem when the computer registers multiple suspend events.
+
If it replies with:
  
=== xfce4-xkb-plugin ===
+
  xdg-settings: unknown desktop environment
There is a bug in version {{Pkg|xkb-plugin}} ''0.5.4.1-1'' which causes xkb-plugin to ''lose keyboard, layout switching and compose key'' settings. As a workaround you may enable ''Use system defaults'' option in keyboard settings. To do so run
 
  xfce4-keyboard-settings
 
Go to ''Layout'' tab and set the ''Use system defaults'' flag, then reconfigure xkb-plugin.
 
  
=== Locales ignored with GDM ===
+
it means that it has failed to detect Xfce as your desktop environment, which is likely due to a missing {{Pkg|xorg-xprop}} package.
Add your locale to {{ic|/var/lib/AccountsService/users/$USER}} (replace {{ic|hu_HU.UTF-8}} with your own locale):
 
[User]
 
Language=hu_HU.UTF-8
 
XSession=xfce
 
You may also do it with sed. Note the backslash before .UTF-8:
 
# sed -i 's/Language=.*/Language=hu_HU\.UTF-8/' /var/lib/AccountsService/users/$USER
 
Restart GDM to take effect.
 
  
 
=== Restore default settings ===
 
=== Restore default settings ===
If for any reason you need to revert back to the default settings, try renaming {{ic|~/.config/xfce4-session/}} and {{ic|~/.config/xfce4/}}

+
Symptoms include:
If the window manager does not load correctly, you maybe got a session error. Typical symptoms of this can include:

Restarting xfce or rebooting your system may resolve the problem but more likely the problem is a corrupt session. Delete the session folder below the {{ic|.cache}} folder:
+
Unable to load a failsafe session.
$ rm -r ~/.cache/sessions/
+
Unable to determine failsafe session name. Possible causes: xfconfd isn't running (D-Bus setup problem); environment variable $XDG_CONFIG_DIRS is set incorrectly (must include "/etc"), or xfce4-session is installed incorrectly.  
  
=== Preferred Applications preferences have no effect ===
+
Restarting Xfce or rebooting your system may solve the problem, but a corrupt session is the likely cause. Delete the session folder:
If you have set your preferred applications with ''exo-preferred-applications'', but they do not seem to be taken into consideration, see [[Xfce#xdg-open integration (Preferred Applications)]]
 
  
=== Action Buttons/Missing Icons ===
+
$ rm -r ~/.cache/sessions/
This happens if icons for some actions (Suspend, Hibernate) are missing from the icon theme, or at least do not have the expected names. First, find out the currently used icon theme in the Settings Manager (→Appearance→Icons). Match this with a subdirectory of {{ic|/usr/share/icons}}. For example, if the icon theme is GNOME, make a note of the directory name {{ic|/usr/share/icons/gnome}}.
 
  
icontheme=/usr/share/icons/gnome
+
Also make sure that the relevant folders in {{ic|$HOME}} are owned by the user starting {{ic|xfce4}}. See [[Chown]].
  
Make sure that the {{Pkg|xfce4-power-manager}} is installed as this contains the needed icons. Now create symbolic links from the current icon theme into the {{ic|hicolor}} icon theme.
+
=== Fonts in window title crashing xfce4-title ===
  
ln -s /usr/share/icons/hicolor/16x16/actions/xfpm-suspend.png  ${icontheme}/16x16/actions/system-suspend.png
+
[[Install]] {{Pkg|ttf-droid}} and {{Pkg|ttf-dejavu}}. See also {{Bug|44382}}.
ln -s /usr/share/icons/hicolor/16x16/actions/xfpm-hibernate.png ${icontheme}/16x16/actions/system-hibernate.png

ln -s /usr/share/icons/hicolor/48x48/actions/xfpm-hibernate.png ${icontheme}/48x48/actions/system-hibernate.png
 
  
Log out and in again, and you should see icons for all actions.
+
=== Laptop lid settings ignored ===
  
=== Enable cedilla ç/Ç instead of ć/Ć ===
+
You may find that the lid close settings in Xfce4 Power Manager are ignored, meaning that the laptop will always suspend on lid close, no matter what settings are chosen in the power manager. This is because the power manager is not set to handle lid close events by default. Instead, ''systemd-logind'' handles the lid close event. To change this behavior so that the power manager handles lid close events, execute the following command:
When you select the keyboard layout "U.S., alternative international" in Settings --> Keyboard --> Layout to enable accents, the typical combination for the cedilla ' + c results in ć instead of ç.To change this suffice edit files gtk.immodules for gtk-2.0  and immodules.cache for gtk-3.0 in line that contains "cedilla" adding both "en" in the list "az:ca:co:fr:gv:oc:pt:sq:tr:wa" but in alphabetical order, staying that way in /etc/gtk-2.0/gtk.immodules
+
$ xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/logind-handle-lid-switch -s false
  
"/usr/lib/gtk-2.0/2.10.0/immodules/im-cedilla.so"
+
{{Note|Under some circumstances, the {{ic|logind-handle-lid-switch}} setting will get set to true when changes are made to the laptop lid actions or the lock on suspend setting. See [https://bugzilla.xfce.org/show_bug.cgi?id&#61;12756#c2]. In this case, you will need to toggle {{ic|logind-handle-lid-switch}} to false again.}}
"cedilla" "Cedilla" "gtk20" "/usr/share/locale" "az:ca:co:en:fr:gv:oc:pt:sq:tr:wa"
 
  
and this in /usr/lib/gtk-3.0/3.0.0/immodules.cache
+
=== User switching action button is greyed out ===
  
"/usr/lib/gtk-3.0/3.0.0/immodules/im-cedilla.so"
+
The ''Switch User'' action button assumes that the ''gdmflexiserver'' executable (provided by [[GDM]]) exists. Thus, if GDM is not being used then the button will be greyed out. See the [https://bugzilla.xfce.org/show_bug.cgi?id=9307 upstream bug report].
"cedilla" "Cedilla" "gtk30" "/usr/share/locale" "az:ca:co:en:fr:gv:oc:pt:sq:tr:wa"
 
  
Then, do
+
A possible workaround is to create an executable script called ''gdmflexiserver'' in {{ic|/usr/bin}} or {{ic|/usr/local/bin}} which calls the greeter switch command provided by the [[display manager]] which is being used.
# echo "export GTK_IM_MODULE=cedilla" >> /etc/environment
 
  
Done. Simply just close and reopen the gtk programs like gedit.
+
* For LXDM - [[LXDM#Simultaneous users and switching users]].
 +
* For LightDM - [[LightDM#User switching]].
  
=== Non ASCII characters when mounting USB sticks ===
+
=== Macros in .Xresources not working ===
A common problem when automounting USB sticks formatted with fat filesystem is the inability to properly show characters as umlauts, ñ, ß, etc. This may be solved by changing the default iocharset to UTF-8, which is easily done adding a line to {{ic|/etc/xdg/xfce4/mount.rc}}:
 
  
[vfat]
+
Xfce loads {{ic|$HOME/.Xresources}} file using {{ic|xrdb}}, but with {{ic|-nocpp}} option to skip preprocessing. For macros to work properly, copy {{ic|/etc/xdg/xfce4/xinitrc}} to {{ic|$HOME/.config/xfce4}} directory and remove {{ic|-nocpp}} option to {{ic|xrdb}} from the resulting file. See [https://bbs.archlinux.org/profile.php?id=104121 this thread].
uid=<auto>
 
shortname=winnt
 
'''utf8=true'''
 
# FreeBSD specific option
 
longnames=true
 
flush=true
 
  
Note that when using utf-8, the system will distinct between upper- and lowercases, potentially corrupting your files, so be careful.
+
=== Cursor theme doesn't change on login ===
  
It is possible to mount vfat devices with ''flush'' option, so that when copying to USB sticks data flushes more often, thus making thunar's progress bar to stays up until finished. Adding ''async'' instead will speed up write ops, but make sure to use ''Eject'' option in Thunar to unmount the stick. Globally, mount options for storage devices present at boot can be set in [[fstab]], and for other devices in [[udev]] rules.
+
Ensure the systemwide XDG cursor is set to your desired cursor theme - see [[Cursor themes#XDG specification]].
  
=== Video tearing when Xfwm compositing is enabled ===
+
== See also ==
This is a known problem. Consider using a standalone compositor like [[Compton]] or [[Xcompmgr]]. Alternatively, you could replace your window manager with something like [[Compiz]] or Kwin ({{aur|kwin-standalone-git}}) which provide their own compositors.

Latest revision as of 15:02, 19 June 2018

Xfce is a lightweight and modular desktop environment currently based on GTK+ 2. To provide a complete user experience, it includes a window manager, a file manager, desktop and panel.

Contents

Installation

Install the xfce4 group. You may also wish to install the xfce4-goodies group which includes extra plugins and a number of useful utilities such as the mousepad editor. Xfce uses the Xfwm window manager by default.

Starting Xfce

Choose Xfce Session from the menu in a display manager of choice, or add exec startxfce4 to Xinitrc.

Note: Do not call the xfce4-session executable directly; startxfce4 is the correct command which, in turn, calls the former when appropriate.

Configuration

Xfce stores configuration options in Xfconf. There are several ways to modify these options:

  • In the main menu, select Settings and the category you want to customize. Categories are programs usually located in /usr/bin/xfce4-* and /usr/bin/xfdesktop-settings.
  • xfce4-settings-editor can see and modify all settings. Options modified here will take effect immediately. Use xfconf-query to change settings from the commandline; see the documentation for details.
  • Settings are stored in XML files in ~/.config/xfce4/xfconf/xfce-perchannel-xml/ which can be edited by hand. However, changes made here will not take effect immediately.

Menu

See Xdg-menu for more info on using the Free Desktop menu system.

Whisker menu

xfce4-whiskermenu-plugin (also part of xfce4-goodies) is an alternate application launcher. It shows a list of favorites, browses through all installed applications through category buttons, and supports fuzzy searching. After package being installed, it can replace 'Applications Menu' as first item in Panel 1 (in 'Settings/Panel/Items' add 'Whisker Menu'...).

Edit entries

A number of graphical tools are available for this task:

  • MenuLibre — An advanced menu editor that provides modern features in a clean, easy-to-use interface.
https://launchpad.net/menulibre || menulibreAUR.
  • Alacarte — Menu editor for GNOME
http://www.gnome.org/ || alacarte
  • XAME — GUI tool written in Gambas designed specifically for editing menu entries in Xfce, it will not work in other environments. (Discontinued)
http://www.redsquirrel87.com/XAME.php[dead link 2017-12-30] || xameAUR

Alternatively, create the file ~/.config/menus/xfce-applications.menu manually. See the example configuration below:

<!DOCTYPE Menu PUBLIC "-//freedesktop//DTD Menu 1.0//EN"
  "http://www.freedesktop.org/standards/menu-spec/1.0/menu.dtd">

The <MergeFile> tag includes the default Xfce menu.

The <Exclude> tag excludes applications which we do not want to appear in the menu. Here we excluded some Xfce default shortcuts, but you can exclude firefox.desktop or any other application.

The <Layout> tag defines the layout of the menu. The applications can be organized in folders or however we wish. For more details see the Xfce wiki.

You can also make changes to the Xfce menu by editing the .desktop files themselves. To hide entries, see Desktop entries#Hide desktop entries. You can edit the application's category by modifying the Categories= line of the desktop entry, see Desktop entries#File example.

Desktop

Transparent background for icon titles

To change the default white background of desktop icon titles to something more suitable, create or edit ~/.gtkrc-2.0:

style "xfdesktop-icon-view" {
    XfdesktopIconView::label-alpha = 10
    base[NORMAL] = "#000000"
    base[SELECTED] = "#71B9FF"
    base[ACTIVE] = "#71B9FF"
    fg[NORMAL] = "#fcfcfc"
    fg[SELECTED] = "#ffffff"
    fg[ACTIVE] = "#ffffff"
}
widget_class "*XfdesktopIconView*" style "xfdesktop-icon-view"

Remove desktop icons

Issue the following command:

$ xfconf-query -c xfce4-desktop -v --create -p /desktop-icons/style -t int -s 0

To reinstate icons on the desktop, issue the same command with a value of 2.

One wallpaper across multihead

Open xfce4-settings-editor and create a new property with the following settings:

Property: /backdrop/screen0/xinerama-stretch
Type: Boolean
Value: TRUE|1|Enabled

Kill window shortcut

Xfce does not have a shortcut to kill a window, for example when a program freezes.

With xorg-xkill, use xkill to interactively kill a window. For the currently active window, use xdotool:

$ xdotool getwindowfocus windowkill

Alternatively:

$ sh -c "xkill -id $(xprop -root -notype | sed -n '/^_NET_ACTIVE_WINDOW/ s/^.*# *\|\,.*$//g p')"

To add the shortcut, use Settings > Keyboard or an application like xbindkeys.

Session

Autostart

To launch custom applications when Xfce starts up, click the Applications Menu > Settings > Settings Manager and then choose the Session and Startup option and click the tab Application Autostart. You will see a list of programs that get launched on startup. To add an entry, click the Add button and fill out the form, specifying the path to an executable you want to run.

Autostart applications are stored as .desktop files in ~/.config/autostart/.

Alternatively, add the commands you wish to run (including setting environment variables) to xinitrc (or xprofile when a display manager is being used).

Tip: Sometimes it might be useful to delay the startup of an application. Note that specifying under Application Autostart a command such as sleep 3 && command does not work; a workaround is to use the syntax sh -c "sleep 3 && command"

Lock the screen

xflock4 is the reference Bash script which is used to lock an Xfce session . It tries consecutively four screen lockers or exits with return code 1 if it fails to find any. Therefore, for xflock4 to succeed, either xscreensaver, gnome-screensaver, slock or xlockmore needs to be installed.

The List of applications/Security#Screen lockers contains a short description of these four screen lockers together with other popular applications.

In particular, light-locker integrates well with xfce4-power-manager: once installed, Xfce Power Manager's setting gains an additional Security tab to configure light-locker and the existing Lock screen when system is going for sleep setting is relocated under this tab. It is then possible to set in this GUI whether the session should be locked upon screensaver activity or whenever the system goes to sleep.

To have xflock4 run light-locker or any custom session locker not among the four cited above, some steps are required. The latest 4.13 version of xfce4-session, not available in the official repositories yet, eases the integration of custom screen lockers with xfclock4 (see the latest xflock4 on git.xfce.org) by checking first for the LockCommand set in the session's xfconf channel. Therefore to use a custom locker with xflock4 one can follow the two steps below:

  1. Use the command line below to set LockCommand, here for example to use light-locker:
    $ xfconf-query -c xfce4-session -p /general/LockCommand -s "light-locker-command --lock" --create -t string
    The command inside the quotes can be adapted accordingly for other screen lockers.
  2. Enhance the xflock4 script with either one of the following methods:
    1. Replace manually /usr/bin/xflock4 with the latest version of the script, so that it calls the command specified in LockCommand.
    2. Install xfce4-session-gitAUR in order to replace the official repository package with the updated 4.13 version which takes into account LockCommand.

The panel lock button in the Action Buttons panel simply executes /usr/bin/xflock4. It should work as expected as long as xflock4 is functioning i.e. one of the native lockers is installed or a custom locker is configured to integrate with it as proposed above.

Suspend

Whenever asked to suspend, Xfce executes the xfce4-session-logout(1) command with the suspend option:

$ xfce4-session-logout --suspend

Whether or not the session is systematically locked on suspend can be configured through the xfconf properties or from the GUI.

To control this state using the CLI: there are two settings that are used, LockScreen and lock-screen-suspend-hibernate, in respectively the session and the power manager xfconf channels. To prevent locking on suspend, turn them to false:

$ xfconf-query -c xfce4-session -p /shutdown/LockScreen -s false
$ xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/lock-screen-suspend-hibernate -s false

Similarly, turn them to true to lock the session on suspend.

The setting can also be controlled from the GUI: open the Session and Startup application and turn the flag Advanced > Lock screen before sleep on or off.

Whenever the suspend keyboard button is pressed, it can be handled by either Xfce's power manager or by systemd-logind. To give precedence to logind, the following xfconf setting must be set to true:

$ xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/logind-handle-suspend-key -n -t bool -s true
Note: To check how systemd-logind handles events whenever it has precedence over Xfce, check logind.conf(5)

Disable saved sessions

Per user, saved sessions can be disabled by executing the following:

$ xfconf-query -c xfce4-session -p /general/SaveOnExit -s false

Then navigate to Applications > Settings > Session and Startup > Sessions and press the Clear saved sessions button to remove all previously saved sessions.

Tip: If the command above does not change the setting persistently, use the following command instead: xfconf-query -c xfce4-session -p /general/SaveOnExit -n -t bool -s false

Alternatively, Xfce kiosk mode can be used to disable the saving of sessions systemwide. To disable sessions, create or edit the file /etc/xdg/xfce4/kiosk/kioskrc and add the following:

[xfce4-session]
SaveSession=NONE

If kiosk mode is not working, the user can set read only permissions for the sessions directory:

$ rm ~/.cache/sessions/* && chmod 500 ~/.cache/sessions

This will prevent Xfce from saving any sessions despite any configuration that specifies otherwise.

Use a different window manager

Note: For the changes to take effect, you will need to clear the saved sessions and ensure that session saving is disabled when logging out for the first time. Once the window manager of choice is running, session saving can be enabled again.

The files specifying the default window manager are found in the following locations:

  • ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-session.xml - per user
  • /etc/xdg/xfce4/xfconf/xfce-perchannel-xml/xfce4-session.xml - systemwide

The default window manager for the user can be set easily using xfconf-query:

$ xfconf-query -c xfce4-session -p /sessions/Failsafe/Client0_Command -t string -sa wm_name

If you want to start the window manager with command line options, see the command below:

$ xfconf-query -c xfce4-session -p /sessions/Failsafe/Client0_Command -t string -t string -s wm_name -s --wm-option

If you need more command line options, simply add more -t string and -s --wm-option arguments to the command.

If you want to change the default window manager systemwide, edit the file specified above manually, changing xfwm4 to the preferred window manager and adding more <value type="string" value="--wm-option"/> lines for extra command line options if needed.

You can also change the window manager by autostarting wm_name --replace using the autostart facility or by running wm_name --replace & in a terminal and making sure the session is saved on logout. Be aware though that this method does not truly change the default manager, it merely replaces it at login. Note that if you are using the autostart facility, you should disable saved sessions as this could lead to the new window manager being started twice after the default window manager.

Theming

XFCE themes are available at xfce-look.org. Xfwm themes are stored in /usr/share/themes/xfce4, and set in Settings > Window Manager. GTK+ themes are set in Settings > Appearance.

To achieve a uniform look for all applications, see Uniform look for Qt and GTK applications.

See also Cursor themes, Icons, and Font configuration.

Sound

Keyboard volume buttons

xfce4-pulseaudio-plugin provides a panel applet which has support for keyboard volume control and volume notifications. As an alternative, you can install xfce4-volumed-pulseAUR, which also provides keybinding and notification control, but without an icon sitting in the panel. This is handy, for example, when using pasystrayAUR at the same time for a finer control.

Alternatively, xfce4-mixer also provides a panel applet and keyboard shortcuts which supports Alsa as well. Note however, that it is based on a feature of GStreamer 0.10 which has been abandoned in 1.0.

For non desktop environment specific alternatives, see List of applications#Volume managers.

Shortcuts

If you are not using an applet or daemon that controls the volume keys, you can map volume control commands to your volume keys manually using Xfce's keyboard settings. For the sound system you are using, see the sections linked to below for the appropriate commands.

Keyboard Shortcuts

Keyboard shortcuts are defined in two places: Settings > Window Manager > Keyboard, and Settings > Keyboard > Shortcuts.

Polkit Authentication Agent

The polkit-gnome agent will be installed along with xfce4-session and autostarted automatically; no user intervention is required. For more information, see Polkit#Authentication agents.

A third party polkit authentication agent for Xfce is also available, see xfce-polkitAUR or xfce-polkit-gitAUR.

Display blanking

Some programs that are commonly used with Xfce will control monitor blanking and DPMS (monitor powersaving) settings. They are discussed below.

Xfce Power Manager

Xfce Power Manager controls blanking and DPMS settings. These settings can be configured in the Power Manager GUI within the Display tab.

Note that when Display power management is turned off, DPMS is fully disabled, it does not mean that Power Manager will simply stop controlling DPMS. It does not disable screen blanking either. To disable both blanking and DPMS, right click on the power manager system tray icon or left click on the panel applet and make sure that the option labelled Presentation mode is ticked.

XScreenSaver

If xscreensaver is installed and runs alongside Xfce Power Manager, it may not be clear which application is in control of blanking and DPMS as both are competing for control of the same settings. Therefore, in a situation where it is important that the monitor not be blanked (when watching a video for instance), it is advisable to disable blanking and DPMS through both applications. To know more about XScreenSaver options, see XScreenSaver#DPMS and blanking settings.

xset

If neither of the above applications are running, then blanking and DPMS settings can be controlled using the xset command, see DPMS#Modifying DPMS and screensaver settings using xset.

Note: There are some issues associated with blanking and resuming from blanking in some configurations. See [1][2].

Tips and tricks

Hide partitions from thunar and xfdesktop

If your installation partitions are shown as mounted devices on the desktop and in Thunar, try to install gvfs. See Udisks#Hide selected partitions for more advanced configuration options.

Screenshots

Xfce has its own screenshot tool, xfce4-screenshooter. It is part of the xfce4-goodies group.

Go to Applications > Settings > Keyboard, Application Shortcuts. Add the xfce4-screenshooter -f (or -w for the active window) command to use the Print key in order to take fullscreen screenshots. See screenshooter's man page for other optional arguments.

Alternatively, an independent screenshot program like scrot can be used.

Disable Terminal F1 and F11 shortcuts

The xfce terminal binds F1 and F11 to help and fullscreen, respectively, which can make using programs like htop difficult. To disable those shortcuts, create or edit its configuration file, then log out and log back in. F10 can disabled in the Preferences menu.

~/.config/xfce4/terminal/accels.scm
(gtk_accel_path "<Actions>/terminal-window/fullscreen" "")
(gtk_accel_path "<Actions>/terminal-window/contents" "")

Terminal color themes or palettes

Terminal color themes or palettes can be changed in GUI under Appearance tab in Preferences. These are the colors that are available to most console applications like Emacs, Vi and so on. Their settings are stored individually for each system user in ~/.config/xfce4/terminal/terminalrc file. There are also so many other themes to choose from. Check forum thread Terminal Colour Scheme Screenshots for hundreds of available choices and themes.

Changing default color theme

Xfce's extra/terminal package comes with a darker colour palette. To change this, append the following in your terminalrc file for a lighter color theme, that is always visible in darker Terminal backgrounds.

~/.config/xfce4/terminal/terminalrc
ColorPalette5=#38d0fcaaf3a9
ColorPalette4=#e013a0a1612f
ColorPalette2=#d456a81b7b42
ColorPalette6=#ffff7062ffff
ColorPalette3=#7ffff7bd7fff
ColorPalette13=#82108210ffff

Terminal tango color theme

To switch to tango color theme, open with your favorite editor

~/.config/xfce4/terminal/terminalrc

And add(replace) these lines:

ColorForeground=White
ColorBackground=#323232323232
ColorPalette1=#2e2e34343636
ColorPalette2=#cccc00000000

Open URLs by middle mouse in terminal

On update to version 0.8 open URL with middle mouse turned off by default and just paste clip to cursor. To enable old behavior fix next option in ${XDG_CONFIG_HOME}/xfce4/terminal/terminalrc (XDG_CONFIG_HOME=${HOME}/.config by default)

${XDG_CONFIG_HOME}/xfce4/terminal/terminalrc
[Configuration]
MiscMiddleClickOpensUri=TRUE

Colour management

Xfce has no native support for colour management. [3] See ICC profiles for alternatives.

Multiple monitors

Xfce has support for multiple monitors. Settings can be configured in the Applications > Settings > Display dialog. For more information, see the display article from the Xfce documentation.

SSH agents

By default Xfce 4.10 will try to load gpg-agent or ssh-agent in that order during session initialization. To disable this, create an xfconf key using the following command:

xfconf-query -c xfce4-session -p /startup/ssh-agent/enabled -n -t bool -s false

To force using ssh-agent even if gpg-agent is installed, run the following instead:

xfconf-query -c xfce4-session -p /startup/ssh-agent/type -n -t string -s ssh-agent

To use GNOME Keyring, simply tick the checkbox Launch GNOME services on startup in the Advanced tab of Session and Startup in Xfce's settings. This will also disable gpg-agent and ssh-agent.

Source: http://docs.xfce.org/xfce/xfce4-session/advanced

Scroll a background window without shifting focus on it

Go to Main Menu > Settings > Window Manager Tweaks > Accessibility tab. Uncheck Raise windows when any mouse button is pressed.

Mouse button modifier

By default, the mouse button modifier in Xfce is set to Alt. This can be changed with xfconf-query. For instance, the following command will set the Super key as the mouse button modifier:

$ xfconf-query -c xfwm4 -p /general/easy_click -n -t string -s "Super"

Strictly speaking, using multiple modifiers is not supported. However, as a workaround, multiple modifiers can be specified if the key names are separated with ><. For instance, to set Ctrl+Alt as the mouse button modifier, you can use the following command:

$ xfconf-query -c xfwm4 -p /general/easy_click -n -t string -s "Ctrl><Alt"

Set the two fingers click to middle click for a touchpad

Tango-edit-clear.pngThis article or section needs language, wiki syntax or style improvements.Tango-edit-clear.png

Reason: Convoluted way of simply configuring Touchpad Synaptics (Discuss in Talk:Xfce#)

If you want the 2 finger click on the touchpad to do a middle click, create or edit the following file:

~/.config/xfce4/xfconf/xfce-perchannel-xml/pointers.xml
<channel name="pointers" version="1.0">
  <property name="SynPS2_Synaptics_TouchPad" type="empty">
    <property name="Properties" type="empty">
      <property name="Synaptics_Tap_Action" type="array">
        <value type="int" value="0"/>
        <value type="int" value="0"/>
        <value type="int" value="0"/>
        <value type="int" value="0"/>
        <value type="int" value="1"/>
        <value type="int" value="2"/>
        <value type="int" value="3"/>
      </property>
    </property>
  </property>
</channel>

The 2 in the array is the middle click.

Limit the minimum brightness of the brightness-slider

Limiting the minimum brightness can be useful for displays which turn off backlight on a brightness level of 0. In xfce4-power-manager 1.3.2 a new hidden option had been introduced to set a minimum brightness value with a xfconf4-property. Add brightness-slider-min-level as an int property in xfconf4. Adjust the int value to get a suitable minimum brightness level.

Adding profile pictures

To add profile pictures for each user to be displayed in the whisker-menu, simply place a 96x96 PNG file in the respective user's home directory with the name .face. For example the PNG file /home/bob/.face for user bob.

Image editing programs like GIMP can be used to convert and scale your favourite images down to 96x96.

Power manager plugin label

The xfconf option show-panel-label of type int controls the label of the power manager, it can be configured for different label formats: it can be set to 0 (no label), 1 (percentage), 2 (remaining time) or 3 (both).

It is also accessible through the power manager plugin GUI in Properties > Show label

Troubleshooting

Desktop icons rearrange themselves

At certain events (such as opening the panel settings dialog) icons on the desktop rearrange themselves. This is because icon positions are determined by files in the ~/.config/xfce4/desktop/ directory. Each time a change is made to the desktop (icons are added or removed or change position) a new file is generated in this directory and these files can conflict.

To solve the problem, navigate to the directory and delete all the files other than the one which correctly defines the icon positions. You can determine which file defines the correct icon positions by opening it and examining the locations of the icons. The topmost row is defined as row 0 and the leftmost column is defined by col 0. Therefore an entry of:

[Firefox]
row=3
col=0

means that the Firefox icon will be located on the 4th row of the leftmost column.

GTK themes not working with multiple monitors

Tango-view-fullscreen.pngThis article or section needs expansion.Tango-view-fullscreen.png

Reason: Which configuration tools? What does ceasing to work mean? Is it that new themes cannot be selected or that themes display incorrectly? Is there a bug report? (Discuss in Talk:Xfce#)

Some configuration tools may corrupt displays.xml, which results in GTK themes under Applications Menu > Settings > Appearance ceasing to work. To fix the issue, delete ~/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml and reconfigure your screens.

Icons do not appear in right-click menus

Note: Despite the deprecation of GConf, this method does still work.

Users may find that icons do not appear when right-clicking options within some applications, including those made with Qt. This problem only appears to happen within Xfce. Run these two commands:

$ gconftool-2 --type boolean --set /desktop/gnome/interface/buttons_have_icons true
$ gconftool-2 --type boolean --set /desktop/gnome/interface/menus_have_icons true

NVIDIA and xfce4-sensors-plugin

To detect and use sensors of nvidia gpu you need to install libxnvctrl and then rebuild xfce4-sensors-plugin with ABS. You also have the option of using xfce4-sensors-plugin-nvidiaAUR which replaces xfce4-sensors-plugin.

Panel applets keep being aligned on the left

Add a separator someplace before the right end and set its "expand" property. [4]

Preferred Applications preferences have no effect

Most applications rely on xdg-open for opening a preferred application for a given file or URL.

In order for xdg-open and xdg-settings to detect and integrate with the Xfce desktop environment correctly, you need to install the xorg-xprop package.

If you do not do that, your preferred applications preferences (set by exo-preferred-applications) will not be obeyed. Installing the package and allowing xdg-open to detect that you are running Xfce makes it forward all calls to exo-open instead, which correctly uses all your preferred applications preferences.

To make sure xdg-open integration is working correctly, ask xdg-settings for the default web browser and see what the result is:

# xdg-settings get default-web-browser

If it replies with:

xdg-settings: unknown desktop environment

it means that it has failed to detect Xfce as your desktop environment, which is likely due to a missing xorg-xprop package.

Restore default settings

If for any reason you need to revert back: to the default settings, rename ~/.config/xfce4-session/ and ~/.config/xfce4/

$ mv ~/.config/xfce4-session/ ~/.config/xfce4-session-bak
$ mv ~/.config/xfce4/ ~/.config/xfce4-bak

Relogin for changes to take effect. If you get Unable to load a failsafe session upon login, see the #Session failure section.

Session failure

Symptoms include:

  • The mouse is an X and/or does not appear at all;
  • Window decorations have disappeared and windows cannot be closed;
  • (xfwm4-settings) will not start, reporting These settings cannot work with your current window manager (unknown);
  • Errors reported by a display manager such as No window manager registered on screen 0.
  • Unable to load a failsafe session:
Unable to load a failsafe session.
Unable to determine failsafe session name.  Possible causes: xfconfd isn't running (D-Bus setup problem); environment variable $XDG_CONFIG_DIRS is set incorrectly (must include "/etc"), or xfce4-session is installed incorrectly. 

Restarting Xfce or rebooting your system may solve the problem, but a corrupt session is the likely cause. Delete the session folder:

$ rm -r ~/.cache/sessions/

Also make sure that the relevant folders in $HOME are owned by the user starting xfce4. See Chown.

Fonts in window title crashing xfce4-title

Install ttf-droid and ttf-dejavu. See also FS#44382.

Laptop lid settings ignored

You may find that the lid close settings in Xfce4 Power Manager are ignored, meaning that the laptop will always suspend on lid close, no matter what settings are chosen in the power manager. This is because the power manager is not set to handle lid close events by default. Instead, systemd-logind handles the lid close event. To change this behavior so that the power manager handles lid close events, execute the following command:

$ xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/logind-handle-lid-switch -s false
Note: Under some circumstances, the logind-handle-lid-switch setting will get set to true when changes are made to the laptop lid actions or the lock on suspend setting. See [5]. In this case, you will need to toggle logind-handle-lid-switch to false again.

User switching action button is greyed out

The Switch User action button assumes that the gdmflexiserver executable (provided by GDM) exists. Thus, if GDM is not being used then the button will be greyed out. See the upstream bug report.

A possible workaround is to create an executable script called gdmflexiserver in /usr/bin or /usr/local/bin which calls the greeter switch command provided by the display manager which is being used.

Macros in .Xresources not working

Xfce loads $HOME/.Xresources file using xrdb, but with -nocpp option to skip preprocessing. For macros to work properly, copy /etc/xdg/xfce4/xinitrc to $HOME/.config/xfce4 directory and remove -nocpp option to xrdb from the resulting file. See this thread.

Cursor theme doesn't change on login

Ensure the systemwide XDG cursor is set to your desired cursor theme - see Cursor themes#XDG specification.
