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 ==
  
== What is Xfce? ==
+
[[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.
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:
+
*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==
+
== Starting Xfce ==
  
Before starting, make sure you have the [[Xorg|X server]] installed and configured correctly.
+
Choose ''Xfce Session'' from the menu in a [[display manager]] of choice, or add {{ic|exec startxfce4}} to [[Xinitrc]].
  
{{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.}}
+
{{Note|Do not call the {{ic|xfce4-session}} executable directly; {{ic|startxfce4}} is the correct command which, in turn, calls the former when appropriate.}}
  
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.
+
== Configuration ==
  
{{Tip|Installing [[Gamin]] (the successor of [[FAM]]) is highly recommended.}}
+
Xfce stores configuration options in [http://docs.xfce.org/xfce/xfconf/start Xfconf]. There are several ways to modify these options:
  
In order to get the xfce4-mixer to work with [[ALSA]], you need to install {{Pkg|gstreamer0.10-base-plugins}}. See [[#OSS|below]] for help with [[OSS]].
+
* 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.
  
== Running Xfce ==
+
=== Menu ===
  
===Automatically at boot time===
+
==== Whisker menu ====
There are two methods to start Xfce (and in fact, any desktop or window manager) at boot time:
+
  
* Run Xfce through a [[Display Manager]]
+
{{Pkg|xfce4-whiskermenu-plugin}} is an alternate application launcher. It shows a list of favorites, browses through all installed applications through category buttons, and supports fuzzy searching.
* Run Xfce automatically using the {{pkg|xorg-xinit}} method at [[Start X at Login]] combining with [[Automatic login to virtual console‎ ]]
+
  
===Manually===
+
==== Edit entries ====
  
{{Note|See [[xinitrc]] for details, such as preserving the logind (and/or consolekit) session.}}
+
A number of graphical tools are available for this task:
  
You can execute:
+
* {{App|XAME|GUI tool written in Gambas designed specifically for editing menu entries in Xfce, it will not work in other environments.|http://www.redsquirrel87.com/XAME.html|{{AUR|xame}}}}
$ startxfce4
+
* {{App|MenuLibre|An advanced menu editor that provides modern features in a clean, easy-to-use interface.|https://launchpad.net/menulibre|{{AUR|menulibre}}}}.
from the console, or configure [[xinitrc]] and use xinit or startx.
+
* {{App|Alacarte|Menu editor for GNOME|http://www.gnome.org/|{{Pkg|alacarte}}}}
  
If you have not created a {{ic|~/.xinitrc}} yet, do so with:
+
Alternatively, create the file {{ic|~/.config/menus/xfce-applications.menu}} manually. See the example configuration below:
  
  $ cp /etc/skel/.xinitrc ~/.xinitrc
+
  <!DOCTYPE Menu PUBLIC "-//freedesktop//DTD Menu 1.0//EN"
 +
  "http://www.freedesktop.org/standards/menu-spec/1.0/menu.dtd">

 +
        <Separator/>
 +
        <Filename>xfce4-session-logout.desktop</Filename>
 +
    </Layout>
 +
</Menu>
  
and add the following line:
+
The {{ic|<MergeFile>}} tag includes the default Xfce menu.
  
exec startxfce4
+
The {{ic|<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 {{ic|firefox.desktop}} or any other application.
  
Example:
+
The {{ic|<Layout>}} tag defines the layout of the menu. The applications can be organized in folders or however we wish. For more details see the [http://wiki.xfce.org/howto/customize-menu  Xfce wiki].
{{hc|~/.xinitrc|<nowiki>#!/bin/sh

if [ -d /etc/X11/xinit/xinitrc.d ]; then
+
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]].
  for f in /etc/X11/xinit/xinitrc.d/*; do

    [ -x "$f" ] && . "$f"

{{Note|

==== Transparent background for icon titles ====
*In case you are wondering, {{ic|dbus-launch}} will be launched by the {{ic|xinitrc.d}} code at the beginning of the file. {{ic|dbus-launch}} starts a dbus-daemon instance to provide communication with PolicyKit.
+
*The proper command for launching Xfce is {{ic|startxfce4}}: do not start {{ic|xfce4-session}} directly, since it is already run by {{ic|startxfce4}} itself.
+
}}
+
  
===Shutting down, rebooting, and automounting from within Xfce===
+
To change the default white background of desktop icon titles to something more suitable, create or edit {{ic|~/.gtkrc-2.0}}:
See [[General Troubleshooting#Session permissions]].
+
  
====Shutdown & reboot from shutdown menu when using systemd====
 
If you are using systemd instead of sysvinit, when trying to shutdown or reboot from the shutdown menu of xfce4 it actually logout to DM; installing {{pkg|systemd-sysvcompat}} corrects this misbehavior.
 
 
==Tips and tricks==
 
===Configuring 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===
 
====How to customize 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"
 
 
==== Replacements for the default 'menu' panel applet ====
 
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.
 
 
====How to remove menu entries from the System menu====
 
===== 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=$ sudo sh -c 'echo "NoDisplay=true" >> firefox.desktop'}} This command appends the text {{ic|1=NoDisplay=true}} to the end of the {{ic|.desktop}} file.
 
 
===== Method 2 =====
 
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/}}.
 
# In a terminal, copy everything from {{ic|/usr/share/applications}} to {{ic|~/.local/share/applications/}}: {{bc|$ cp /usr/share/applications/* ~/.local/share/applications/}}
 
# 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.
 
 
===== 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:
 
 
{{bc|<nowiki>
 
{{bc|<nowiki>
<!DOCTYPE Menu PUBLIC "-//freedesktop//DTD Menu 1.0//EN"
+
style "xfdesktop-icon-view" {
  "http://www.freedesktop.org/standards/menu-spec/1.0/menu.dtd">
+
    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>}}
  
<Menu>
+
==== Remove Thunar options from right-click menu ====
    <Name>Xfce</Name>
+
    <MergeFile type="parent">/etc/xdg/menus/xfce-applications.menu</MergeFile>
+
  
    <Exclude>
+
Issue the following command:
        <Filename>xfce4-run.desktop</Filename>
+
  
        <Filename>exo-terminal-emulator.desktop</Filename>
+
$ xfconf-query -c xfce4-desktop -v --create -p /desktop-icons/style -t int -s 0
        <Filename>exo-file-manager.desktop</Filename>
+
        <Filename>exo-mail-reader.desktop</Filename>
+
        <Filename>exo-web-browser.desktop</Filename>
+
  
        <Filename>xfce4-about.desktop</Filename>
+
==== Kill window shortcut ====
        <Filename>xfhelp4.desktop</Filename>
+
    </Exclude>
+
  
    <Layout>
+
Xfce does not have a shortcut to kill a window, for example when a program freezes.
        <Merge type="all"/>
+
        <Separator/>
+
  
        <Menuname>Settings</Menuname>
+
With {{Pkg|xorg-xkill}}, use {{ic|xkill}} to interactively kill a window. For the currently active window, use {{Pkg|xdotool}}:
        <Separator/>
+
  
        <Filename>xfce4-session-logout.desktop</Filename>
+
$ xdotool getwindowfocus windowkill
    </Layout>
+
  
</Menu>
+
Alternatively:
</nowiki>}}
+
  
The {{ic|<MergeFile>}} tag includes the default Xfce menu in our file. This is important.
+
$ xkill -id "$(xprop -root -notype | sed -n '/^_NET_ACTIVE_WINDOW/ s/^.*# *\|\,.*$//g p')"
  
The {{ic|<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 {{ic|firefox.desktop}} or any other application.
+
To add the shortcut, use ''Settings > Keyboard'' or an application like {{pkg|xbindkeys}}.
  
The {{ic|<Layout>}} tag defines the layout of the menu. The applications can be organized in folders or however we wish. For more details see the aforementioned Xfce wiki page.
+
=== Session ===
  
===== Method 4 =====
+
==== Startup applications ====
Alternatively a tool called [http://lxmed.sourceforge.net/ lxmed] can be used. Lxmed is a GUI tool written in Java for editing menu entires in LXDE, but it also works in Xfce4. Lxmed is available in the {{AUR|lxmed}} package from the [[AUR]].
+
  
==== But what do you do with menu entries which do not show up in /usr/share/applications (e.g., apps installed via Wine)? ====
+
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''.
I have found some shortcuts that show in the category “Other” in this directory:
+
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.
{{ic|~/.local/share/applications/wine/}}.
+
  
====Panel autohide delay====
+
Alternatively, add the commands you wish to run (including setting environment variables) to [[xinitrc]] (or [[xprofile]] when a [[display manager]] is being used).
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====
+
===== Delay application startup =====
  
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 '''wmctrl''' package.
+
Sometimes it might be useful to delay the startup of an application. Specifying a command such as {{ic|sleep 3 && command}} under ''Application Autostart'' does not work. As a workaround, one can use the following syntax instead:
  
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}}).
+
sh -c "sleep 3 && command"
  
#!/bin/bash
+
==== Lock the screen ====
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
+
  
 +
To lock an Xfce4 session through the ''xflock4'' script one of {{Pkg|xscreensaver}}, {{Pkg|gnome-screensaver}}, {{Pkg|slock}} or {{Pkg|xlockmore}} packages needs to be installed.
 +
Alternatively you can set a lock command with
  
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.
+
$ xfconf-query -c xfce4-session -p /general/LockCommand -s "light-locker-command -l" --create -t string''
  
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)
+
If you want to update the command, you can use
  
  xfconf-query -c xfce4-panel -p /panels/panel-$ID/disable-struts -n -t bool -s true
+
  $ xfconf-query -c xfce4-session -p /general/LockCommand -s "light-locker-command -l"
  
=== Desktop ===
+
See [[List of applications/Security#Screen lockers]] for a comprehensive list of screen lockers.
  
==== Use a transparent background for desktop icon titles ====
+
{{Tip|The {{Pkg|light-locker}} session locker integrates with {{Pkg|xfce4-power-manager}}. If light-locker is installed, a ''Security'' tab is added to the power manager settings and the existing ''Lock screen when system is going for sleep'' setting is relocated under the ''Security'' tab.}}
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 on the desktop ====
+
{{Note|1=The ''xflock4'' script can also be modified manually as described in the post [https://bbs.archlinux.org/viewtopic.php?id=189484]. To avoid having the changes overwritten on upgrades, you might wish to copy ''xflock4'' to {{ic|/usr/local/bin}} and make the changes to that copy as this will take precedence over the packaged version in {{ic|/usr/bin}}.}}
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"
+
==== User switching ====
KERNEL=="sda2", ENV{UDISKS_PRESENTATION_HIDE}="1"
+
  
Would show all partitions with the exception of sda1 and sda2 on your desktop.
+
Xfce4 has support for user switching when used with a [[Display manager]] that has this functionality - examples being [[LightDM]] and [[GDM]]. Please consult your display manager's wiki page for more information. When you have a display manager installed and configured correctly you can switch users from the 'action buttons' menu item in the panel.
  
==== Switch to old desktop right click menu without Thunar things ====
+
For the User Switch action button to work without GDM, a workaround is required:
xfconf-query -c xfce4-desktop -v --create -p /desktop-icons/style -t int -s 0
+
* For LXDM - [[LXDM#Simultaneous users and switching users]].
 +
* For LightDM - [[LightDM#User switching under Xfce4]].
  
==== Adding the kill window shortcut ====
+
==== Disable saved sessions ====
  
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.
+
Per user, saved sessions can be disabled by executing the following:
 +
$ xfconf-query -t bool -c xfce4-session -p /general/SaveOnExit -s false
 +
Then navigate to ''Applications'' -> ''Settings'' -> ''Session and Startup'' -> ''Sessions'' and click the ''Clear saved sessions'' button.
  
Create a script in {{ic|~/.config/xfce4/killwindow.sh}} with this content and make it executable (you can use {{ic|chmod 755 killwindow.sh}}).
+
{{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}}}}
  
xkill -id "`xprop -root -notype | sed -n '/^_NET_ACTIVE_WINDOW/ s/^.*# *\|\,.*$//g p'`"
+
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:
  
Now associate a shortcut using {{ic|Settings -> Keyboard}} to that script.
+
[xfce4-session]
 +
SaveSession=NONE
  
=== XFWM4 ===
+
If kiosk mode is not working, the user can set read only permissions for the sessions directory:
==== How to enable the compositor in Xfce ====
+
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
+
  $ rm ~/.cache/sessions/* && chmod 500 ~/.cache/sessions
  
==== Disable window roll-up ====
+
This will prevent Xfce from saving any sessions despite any configuration that specifies otherwise.
xfconf-query -c xfwm4 -p /general/mousewheel_rollup -s false
+
  
==== Disable/enable automatic resizing/tiling of windows at edge of screen ====
+
==== Default window manager ====
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
+
{{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.}}
xfconf-query -c xfwm4 -p /general/tile_on_move -s true  # To enable
+
  
=== Commands for the settings manager ===
+
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
  
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:
+
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-accessibility-settings
+
If you want to start the window manager with command line options, see the command below:
xfce4-power-manager-settings
+
  $ xfconf-query -c xfce4-session -p /sessions/Failsafe/Client0_Command -t string -t string -s '''wm_name''' -s '''--wm-option'''
  xfce4-settings-editor
+
If you need more command line options, simply add more {{ic|-t string}} and {{ic|-s '''--wm-option'''}} arguments to the command.
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:
+
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.
  
$ grep '^Exec=' /usr/share/applications/xfce*settings* | sed -e 's_^.*=_ _'
+
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.
  
===Session===
+
=== Theming ===
====Customizing Startup Applications====
+
This includes getting necessary environment variables into the GUI runtime.
+
  
* Copy the file {{ic|/etc/xdg/xfce4/xinitrc}} to {{ic|~/.config/xfce4/}}
+
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''.
* 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
+
  
====Switch between users====
+
To achieve a uniform look for all applications, see [[Uniform look for Qt and GTK applications]].
Xfce4 allows this behavior under the 'action buttons' menu item.  Currently, both [[gdm]] and [[Lightdm#User_switching_under_xfce4|lightdm]] provide this functionality.
+
  
==== Modify XML settings files directly ====
+
See also [[Cursor themes]], [[Icons]], and [[Font configuration]].
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.
+
  
===Removable Devices===
+
=== Sound ===
If you want an icon appearing on your desktop and in thunar when you plug in external devices, make sure gvfs is installed:
+
  
# pacman -S --needed gvfs
+
==== Xfce4 mixer ====
  
You could also need to install gvfs-afc (read [https://bbs.archlinux.org/viewtopic.php?pid=889018 this discussion]):
+
{{Note|Xfce4 mixer and Xfce4 volumed are no longer being maintained upstream as they cannot be ported to GStreamer 1.0. For more information, see the 4.12 [http://www.xfce.org/about/news/?post&#61;1425081600 news post].}}
  
# pacman -S gvfs-afc
+
Xfce4 mixer, provided by {{Pkg|xfce4-mixer}}, is the GUI mixer app and panel plugin from the Xfce team. It is part of the xfce4 group. For [[PulseAudio]] and [[OSS]] support, you will need to install {{Pkg|gstreamer0.10-good-plugins}} if it is not installed already.
  
It is also a good idea to install thunar-volman (included in the {{ic|xfce4-goodies}} group):
+
You might need to change the default sound card for Xfce4 mixer to function correctly. For further details, such as how to set the default sound card, see [[Advanced Linux Sound Architecture#Set the default sound card]]. Alternatively you can use [[PulseAudio]] together with {{Pkg|pavucontrol}} or [[OSS]]. For OSS, see [[OSS#Applications that use GStreamer]].
  
# pacman -S thunar-volman
+
If you did need to change the default soundcard, logout to ensure that the changes take effect.
  
Udisk and a udisk wrapper are recommended if you want to automount optical and external drives easily
+
===== Change default sound card in Xfce4 mixer =====
  
* [http://igurublog.wordpress.com/downloads/script-devmon/ devmon] - devmon ([https://aur.archlinux.org/packages.php?ID=45842 AUR]) is a configuration-less bash wrapper script for udisks which automounts optical discs and removable drives. It can also selectively autostart apps or execute commands after mounting, ignore specified devices and volume labels, and unmount removable drives.
+
In some cases (when using [[PulseAudio]] or {{AUR|xfce4-volumed}} for instance) it might be necessary to change the default sound card in Xfce4 Mixer in order for volume control to work as expected. [http://grumbel.blogspot.co.uk/2011/10/fixing-volume-control-in-xfce4.html]
  
===How to add themes to XFCE===
+
To change the default sound card, open ''xfce4-settings-editor'' and navigate to '''xfce4-mixer''' and  check the entries under '''sound-cards'''. Locate the correct entry for the card you are using and then replace the values of '''sound-card''' and '''active-card''' with the entry. If you are using PulseAudio then the entry will likely be similar to the following: '''PlaybackInternalAudioAnalogStereoPulseAudioMixer'''. Then logout for the changes to take effect.
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.
+
==== xfce4-alsa-plugin ====
  
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.
+
If you do not use PulseAudio, you can install {{AUR|xfce4-alsa-plugin}}. It provides a simple panel plugin with the ability to control ALSA volume, though it does not support keyboard volume buttons.
  
4. GTK theme is available here:
+
==== Keyboard volume buttons ====
Menu --> Settings --> Appearance
+
You select your xfwm theme in:
+
Menu --> Settings --> Window Manager
+
  
=== Cursors ===
+
If the {{Pkg|xfce4-mixer}} package is version {{ic|4.10.0-3}} or greater, then the mixer panel applet provides the ability to control the volume using the keyboard. However, volume notifications will not be shown. Alternatively, {{AUR|xfce4-volumed}} maps volume keys to Xfce4 mixer, and displays notifications through Xfce4-notifyd.
Main article: [[X11 Cursors]]
+
If you are using PulseAudio and you do not wish to use Xfce4 Mixer at all, install {{AUR|xfce4-pulseaudio-plugin}}. This provides a panel applet which has support for keyboard volume control and volume notifications.
  
If you have alternative X cursor themes installed, Xfce can find them with:
+
For non desktop environment specific alternatives, see [[List of applications#Volume managers]].
Menu --> Settings --> Mouse --> Theme
+
  
=== Icons ===
+
===== Shortcuts =====
1. 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].
+
  
2. Go to the directory where you downloaded the icon pack and extract it. Example {{ic|tar -xzf /home/user/downloads/icon-pack.tar.gz}}.
+
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.
 +
*ALSA: see [[Advanced Linux Sound Architecture#Keyboard volume control]].
 +
*PulseAudio: see [[PulseAudio#Keyboard volume control]]
 +
*OSS: see [[OSS#Using multimedia keys with OSS]].
  
3. Move the extracted folder containing the icons to {{ic|/usr/share/icons}} (if you want all users on the system to make use of the icons) or {{ic|~/.icons}} (if only you want to use the icons).
+
=== Keyboard Shortcuts ===
  
Optional: run {{ic|gtk-update-icon-cache -f -t ~/.icons/<theme_name>}} to update icon cache
+
Keyboard shortcuts are defined in two places: ''Settings > Window Manager > Keyboard'', and ''Settings > Keyboard > Shortcuts''.
  
4. Switch your icons by going to:
+
=== Polkit Authentication Agent ===
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.
+
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]].
  
=== Fonts ===
+
A third party polkit authentication agent for Xfce is also available, see {{AUR|xfce-polkit-git}}.
  
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
+
=== Display blanking ===
  
You could also try using a custom DPI setting.
+
{{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].}}
  
=== Sound ===
+
Some programs that are commonly used with Xfce will control monitor blanking and [[DPMS]] (monitor powersaving) settings. They are discussed below.
  
==== Configuring xfce4-mixer ====
+
;Xfce Power Manager
 +
Xfce Power Manager will control blanking and DPMS settings. These settings can be configured by running ''xfce4-power-manager-settings'' and clicking the ''Display'' tab. Note that unticking the ''Handle display power management'' option means that the Power Manager will disable DPMS - it does not mean that the Power Manager will relinquish control of DPMS. Also note that it will not disable screen blanking. 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.
  
{{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.
+
;XScreenSaver
 +
{{Out of date|With xfce4-power-manager>1.5.1 the issue described below should in theory no longer apply. [http://git.xfce.org/xfce/xfce4-power-manager/commit/?id&#61;a805071464ecf0fee27d59de15620b035d855eb0]}}
 +
See [[XScreenSaver#DPMS and blanking settings]]. Note that if XScreenSaver is running alongside Xfce Power Manager, it may not be entirely clear which application is in control of blanking and DPMS as both applications 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 film for instance), it is advisable to disable blanking and DPMS through both applications.
  
  GStreamer was unable to detect any sound devices. Some sound system specific GStreamer packages may be missing. It may also be a permissions problem.
+
;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]].
  
(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]].
+
== Tips and tricks ==
  
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}}.
+
=== Hide partitions from thunar and xfdesktop ===
  
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}}.
+
See [[Udisks#Hide selected partitions]].
  
==== How do I get xfce4-mixer and OSS4 to work together? ====
+
=== Screenshots ===
  
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 gstreamer0.10-good-plugins yourself. Download the PKGBUILD and other files needed from ABS or [http://projects.archlinux.org/svntogit/packages.git/tree/gstreamer0.10-good/repos here], edit the PKGBUILD, add --enable-oss.  
+
Xfce has its own screenshot tool, {{pkg|xfce4-screenshooter}}. It is part of the {{grp|xfce4-goodies}} group.
  
  ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var \
+
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.
    '''--enable-oss \'''
+
    --disable-static --enable-experimental \
+
    --disable-schemas-install \
+
    --disable-hal \
+
    --with-package-name="GStreamer Good Plugins (Archlinux)" \
+
    --with-package-origin="http://www.archlinux.org/"
+
  
and then run makepkg -i.  
+
Alternatively, an independent screenshot program like [[Taking a screenshot#scrot|scrot]] can be used.
  
  makepkg -i
+
=== Disable Terminal F1 and F11 shortcuts ===
  
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.
+
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.

=== Terminal color themes or palettes ===
  
Go to
+
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.
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 =====
+
==== Changing default color theme ====
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:
+
XFCE's {{ic|extra/terminal}} package comes with a darker color palette. To change this, append the following in your terminalrc file for a lighter color theme, that is always visible in darker Terminal backgrounds.
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.
+
~/.config/xfce4/terminal/terminalrc
  
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.

=== Colour management ===
  
$ xfconf-query -c xfce4-mixer -p /active-card -s `xfconf-query -c xfce4-mixer -p /sound-card`
+
Xfce has no native support for colour management. [https://bugzilla.xfce.org/show_bug.cgi?id=8559] See [[ICC profiles]] for alternatives.
  
===== Volumeicon =====
+
=== Multiple monitors ===
  
{{pkg|volumeicon}} is an alternative to xfce4-volumed in the community repo also handling keybindings and notifications through {{pkg|xfce4-notifyd}}.
+
As of {{Pkg|xfce4-settings}} version 4.11.4, 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.
  
==== Adding startup/boot sound ====
+
=== SSH agents ===
  
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:
+
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:
  
  aplay /boot/startupsound.wav
+
  xfconf-query -c xfce4-session -p /startup/ssh-agent/enabled -n -t bool -s false
  
The file location and filename can be whatever you want, but naming it descriptively and putting it in /boot keeps things tidy.
+
To force using ssh-agent even if gpg-agent is installed, run the following instead:
  
=== xdg-open integration (Preferred Applications) ===
+
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 [[pacman|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.
+
=== Scroll a background window without shifting focus on it ===
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:
+
Go to ''Main Menu > Settings > Window Manager Tweaks > Accessibility'' tab.
 +
Uncheck ''Raise windows when any mouse button is pressed''.
  
# xdg-settings get default-web-browser
+
=== Mouse button modifier ===
  
If it replies with:
+
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:
  
  xdg-settings: unknown desktop environment
+
  $ xfconf-query -c xfwm4 -p /general/easy_click -n -t string -s "Super"
  
it means that it has failed to detect XFCE as your desktop environment, which is likely due to a missing {{Pkg|xorg-xprop}} package.
+
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:
  
=== Screenshots ===
+
$ xfconf-query -c xfwm4 -p /general/easy_click -n -t string -s "Ctrl><Alt"
  
==== Using print-screen key ====
+
== Troubleshooting ==
  
A simple way is to use a command-line screenshot utility:
+
=== Action buttons are missing icons ===
  
# pacman -S scrot
+
This happens if icons for some actions (Suspend, Hibernate) are missing from the icon theme, or do not have the expected names. To fix this, install an icon theme which has the necessary icons already added; see [[Icons#Xfce icons]].
  
Then go to:
+
Then, you can switch to that icon theme using Applications -> Settings -> Appearance -> Icons.
  
XFCE Menu  -->  Settings  -->  Keyboard  >>>  Application Shortcuts.
+
Alternatively you can use the required icons provided by the icon theme you installed in your current icon theme. To do so, you first need to find out what the currently used icon theme is called. You can do so by using the command below:
  
Add the "scrot" command to use the "PrintScreen" key.
+
$ xfconf-query -c xsettings -p /Net/IconThemeName
  
All screenshots will be placed in your home folder with unique names (i.e. {{ic|2009-02-19-063052_1280x1024_scrot.png}}).
+
Then set the following variable:
  
====Screenshooter====
+
$ icontheme=/usr/share/icons/''theme-name''
  
There is also an a screenshot plugin for the Xfce panel, which can be used instead of scrot, that is available in extra:
+
where ''theme-name'' is the name of the current icon theme.
  
# pacman -S xfce4-screenshooter
+
Then create symbolic links from the current icon theme into the icon theme providing the icons (this example assumes the icons are being provided by the {{AUR|elementary-xfce-icons}} theme.)
  
You can add a keyboard binding for it using the command
+
ln -s /usr/share/icons/elementary-xfce/apps/16/system-suspend.svg          ${icontheme}/16x16/actions/system-suspend.svg
 +
ln -s /usr/share/icons/elementary-xfce/apps/16/system-suspend-hibernate.svg ${icontheme}/16x16/actions/system-hibernate.svg

Log out and in again, and you should see icons for all actions.
  
instead of "scrot". You will get a dialog window after pressing "Print" where you can copy the image to the clipboard or save it.
+
=== Desktop icons rearrange themselves ===
  
=== Change mount options ===
+
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.
  
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 utf8, which is easily done adding a line to {{ic|/etc/xdg/xfce4/mount.rc}}:
+
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:
  
  [vfat]
+
  [Firefox]
  uid=<auto>
+
  row=3
  shortname=winnt
+
  col=0
'''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.
+
means that the Firefox icon will be located on the 4th row of the leftmost column.
  
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.
+
=== GTK themes not working with multiple monitors ===
  
===Terminal tango color theme===
+
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.
Open with your favorite editor
+
  
~/.config/Terminal/terminalrc
+
=== Icons do not appear in right-click menus ===
  
And add(replace) this lines:
+
{{Note|Despite the deprecation of GConf, this method does still work.}}
  
ColorForeground=White
+
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:
ColorBackground=#323232323232
+
ColorPalette1=#2e2e34343636
+
ColorPalette2=#cccc00000000
+
ColorPalette3=#4e4e9a9a0606
+
ColorPalette4=#c4c4a0a00000
+
ColorPalette5=#34346565a4a4
+
ColorPalette6=#757550507b7b
+
ColorPalette7=#060698989a9a

+
ColorPalette16=#eeeeeeeeecec
+
  
=== Colour management ===
+
$ gconftool-2 --type boolean --set /desktop/gnome/interface/buttons_have_icons true
xfce4-settings-manager does not yet have any colour management / calibration settings, nor is there any specific XFCE program to characterise your monitor.
+
$ gconftool-2 --type boolean --set /desktop/gnome/interface/menus_have_icons true
  
==== Loading a profile ====
+
=== Keyboard settings are not saved in xkb-plugin ===
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.).
+
There is a bug in {{Pkg|xfce4-xkb-plugin}} ''0.5.4.1-1'' which causes it to lose keyboard, layout switching and compose key settings. [https://bugzilla.xfce.org/show_bug.cgi?id=10226] As a workaround, enable ''Use system defaults'' in {{ic|xfce4-keyboard-settings}}, then reconfigure ''xfce4-xkb-plugin''.
  
See [[ICC_Profiles#Loading_ICC_Profiles]] for more information.
+
=== NVIDIA and xfce4-sensors-plugin ===
  
==== Creating a profile ====
+
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}}.
  
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 [https://aur.archlinux.org/packages.php?ID=25883 dispcalGUI] from [[AUR]].
+
=== Panel applets keep being aligned on the left ===
  
Another option is {{ic|gnome-control-center}} (available in extra), which has a much simpler GUI, but less options and requires installing some Gnome dependencies. In order to start the calibration from the command line, first do {{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 commabnd {{ic|gcm-calibrate --device "xrandr-Lenovo Group Limited"}}.
+
Add a separator someplace before the right end and set its "expand" property. [https://forums.linuxmint.com/viewtopic.php?f=110&t=155602}]
{{Note|1=It seems like you need to run the full gnome-control-center 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.
+
=== Preferred Applications preferences have no effect ===
  
=== XDG User Directories ===
+
Most applications rely on [[xdg-open]] for opening a preferred application for a given file or URL.
freedesktop.org specifies the "well known" user directories like the desktop folder and the music folder. The {{Pkg|xdg-user-dirs}} to manage them and it also handles localization (i.e. translation) of the filenames.
+
# pacman -S xdg-user-dirs
+
If you want to use the directories with your localized names, run the following command on your user:
+
$ xdg-user-dirs-update
+
If you want to revert to English, run the following:
+
$ LC_ALL=C xdg-user-dirs-update
+
It then creates localized (or English) versions of these directories in your home directory and sets up a config file in $(XDG_CONFIG_HOME)/user-dirs.dirs (XDG_CONFIG_HOME defaults to ~/.config). The Xfce and other softwares complying the freedesktop.org knows that is where those types of files should go by default.
+
  
In the case of the French:
+
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.
  
{{hc|~/.config/user-dirs.locale|
+
If you do not do that, your preferred applications preferences (set by exo-preferred-applications) will not be obeyed.
fr_FR}}
+
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.
{{hc|~/.config/user-dirs.dirs|<nowiki>
+
XDG_DESKTOP_DIR="$HOME/Bureau"
+
XDG_DOWNLOAD_DIR="$HOME/Téléchargements"
+
XDG_TEMPLATES_DIR="$HOME/Exemples"
+
XDG_PUBLICSHARE_DIR="$HOME/Public"
+
XDG_DOCUMENTS_DIR="$HOME/Documents"
+
XDG_MUSIC_DIR="$HOME/Musiques"
+
XDG_PICTURES_DIR="$HOME/Images"
+
XDG_VIDEOS_DIR="$HOME/Vidéos"</nowiki>}}
+
  
You can edit these files directly by using text editor.
+
To make sure xdg-open integration is working correctly, ask ''xdg-settings'' for the default web browser and see what the result is:
  
== Troubleshooting ==
+
# xdg-settings get default-web-browser
  
=== xfce4-power-manager is not working ===
+
If it replies with:
Check you have added dbus to the {{ic|DAEMONS}} array in {{ic|/etc/[[rc.conf]]}}.
+
  
=== Xfce4-xkb-plugin settings issue ===
+
  xdg-settings: unknown desktop environment
There is a bug in version ''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.
+
  
=== Thunar does not display any thumbnail ===
+
it means that it has failed to detect Xfce as your desktop environment, which is likely due to a missing {{Pkg|xorg-xprop}} package.
  
Thunar relies on '''Tumbler''' to generate thumbnails. You can install Tumbler by issuing
+
=== Restore default settings ===
  
pacman -S tumbler
+
If for any reason you need to revert back: to the default settings, rename {{ic|~/.config/xfce4-session/}} and {{ic|~/.config/xfce4/}}
  
More details in [[Thunar#Thunar_Thumbnailers|Thunar's page]].
+
$ mv ~/.config/xfce4-session/ ~/.config/xfce4-session-bak
 +
$ mv ~/.config/xfce4/ ~/.config/xfce4-bak
  
=== Locales ignored with GDM ===
+
Relogin for changes to take effect. If you get {{ic|Unable to load a failsafe session}} upon login, see the [[#Session failure]] section.
Become superuser and add your locale to /var/lib/AccountsService/users/$USER:
+
su -c "nano /var/lib/AccountsService/users/$USER"
+
Replace 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:
+
su -c "sed -i 's/Language=.*/Language=hu_HU\.UTF-8/' /var/lib/AccountsService/users/$USER"
+
Restart GDM to take effect.
+
  
=== Restore default settings ===
+
=== Session failure ===
If for any reason you need to revert back to the default settings, try renaming {{ic|~/.config/xfce4-session/}} and {{ic|~/.config/xfce4/}}
+
  
$ mv ~/.config/xfce4-session/ ~/.config/xfce4-session-bak
+
Symptoms include:
$ mv ~/.config/xfce4/ ~/.config/xfce4-bak
+
  
Logout and login for changes to take effect.  If upon logging in you get an error window with the heading "Unable to load a failsafe session," see the [[Xfce#Session_failure|Session Failure]] section on this page.
+
* The mouse is an X and/or does not appear at all;
 +
* Window decorations have disappeared and windows cannot be closed;
 +
* ({{ic|xfwm4-settings}}) will not start, reporting {{ic|These settings cannot work with your current window manager (unknown)}};
 +
* Errors reported by a [[display manager]] such as {{ic|No window manager registered on screen 0}}.
 +
* Unable to load a failsafe session:
  
=== NVIDIA and xfce4-sensors-plugin ===
+
Unable to load a failsafe session.
To detect and use sensors of nvidia gpu you need to install {{AUR|libxnvctrl}} and then recompile {{Pkg|xfce4-sensors-plugin}} package.
+
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.  
  
=== Session failure ===
+
Restarting xfce or rebooting your system may solve the problem, but a corrupt session is the likely cause. Delete the session folder:
If the window manager does not load correctly (The mouse is a X and you cannot close windows) you maybe got an session error.
+
To remove a corrupt session you can delete the session folder at the {{ic|.cache}} folder.
+
# rm -r ~/.cache/sessions/
+
The easy way to reload the session is to reboot the computer. You can also restart xfce.
+
  
=== Clock/notification area no longer pushed to the right edge of the panel in Xfce 4.10 ===
+
$ rm -r ~/.cache/sessions/
  
This is due to a change in the Window Buttons panel plugin which no longer expands to fill the available space.
+
Also make sure that the relevant folders in {{ic|$HOME}} are owned by the user starting {{ic|xfce4}}. See [[Chown]].
  
To emulate the old behavior, add a transparent separator between the window buttons and the clock/notification area, setting its expand property.
+
=== Fonts in window title crashing xfce4-title ===
  
=== Preferred Applications preferences have no effect ===
+
[[Install]] {{Pkg|ttf-droid}} and {{Pkg|ttf-dejavu}}. See also {{Bug|44382}}.
  
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_.28Preferred_Applications.29]]
+
=== Laptop lid settings ignored ===
  
=== Action Buttons in the panel are missing icons ===
+
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, logind handles the lid close event. To change this behavior so that the 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 that each time the laptop lid settings are changed in the power manager, this setting will be reset.
  
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}}.
+
===  Rendering issues with Adwaita theme ===
  
icontheme=/usr/share/icons/gnome
+
Since the upgrade of gnome-themes-standard from 3.18.0-1 version to 3.20.0-1 the Adwaita theme exhibits several issues when being used in Xfce, like a frame around the notification area and dark background of the tooltip in eclipse.
  
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.
+
A ugly solution is to downgrade the {{Pkg|gnome-themes-standard}} to the old 3.18.0-1 meanwhile. The package can be downloaded at:
 +
$ wget <nowiki>https://archive.archlinux.org/repos/2016/04/08/extra/os/$(uname -m)/gnome-themes-standard-3.18.0-1-$(uname -m).pkg.tar.xz</nowiki>
 +
and installed via pacman's {{ic|-U}} option.

Latest revision as of 16:59, 10 July 2016

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

Whisker menu

xfce4-whiskermenu-plugin is an alternate application launcher. It shows a list of favorites, browses through all installed applications through category buttons, and supports fuzzy searching.

Edit entries

A number of graphical tools are available for this task:

  • XAME — GUI tool written in Gambas designed specifically for editing menu entries in Xfce, it will not work in other environments.
http://www.redsquirrel87.com/XAME.html || xameAUR
  • 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

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">

<Menu>
    <Name>Xfce</Name>
    <MergeFile type="parent">/etc/xdg/menus/xfce-applications.menu</MergeFile>

    <Exclude>
        <Filename>xfce4-run.desktop</Filename>
        <Filename>exo-terminal-emulator.desktop</Filename>
        <Filename>exo-file-manager.desktop</Filename>
        <Filename>exo-mail-reader.desktop</Filename>
        <Filename>exo-web-browser.desktop</Filename>
        <Filename>xfce4-about.desktop</Filename>
        <Filename>xfhelp4.desktop</Filename>
    </Exclude>

    <Layout>
        <Merge type="all"/>
        <Separator/>
        <Menuname>Settings</Menuname>
        <Separator/>
        <Filename>xfce4-session-logout.desktop</Filename>
    </Layout>
</Menu>

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 Thunar options from right-click menu

Issue the following command:

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

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:

$ 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

Startup applications

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.

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

Delay application startup

Sometimes it might be useful to delay the startup of an application. Specifying a command such as sleep 3 && command under Application Autostart does not work. As a workaround, one can use the following syntax instead:

sh -c "sleep 3 && command"

Lock the screen

To lock an Xfce4 session through the xflock4 script one of xscreensaver, gnome-screensaver, slock or xlockmore packages needs to be installed. Alternatively you can set a lock command with

$ xfconf-query -c xfce4-session -p /general/LockCommand -s "light-locker-command -l" --create -t string

If you want to update the command, you can use

$ xfconf-query -c xfce4-session -p /general/LockCommand -s "light-locker-command -l"

See List of applications/Security#Screen lockers for a comprehensive list of screen lockers.

Tip: The light-locker session locker integrates with xfce4-power-manager. If light-locker is installed, a Security tab is added to the power manager settings and the existing Lock screen when system is going for sleep setting is relocated under the Security tab.
Note: The xflock4 script can also be modified manually as described in the post [1]. To avoid having the changes overwritten on upgrades, you might wish to copy xflock4 to /usr/local/bin and make the changes to that copy as this will take precedence over the packaged version in /usr/bin.

User switching

Xfce4 has support for user switching when used with a Display manager that has this functionality - examples being LightDM and GDM. Please consult your display manager's wiki page for more information. When you have a display manager installed and configured correctly you can switch users from the 'action buttons' menu item in the panel.

For the User Switch action button to work without GDM, a workaround is required:

Disable saved sessions

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

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

Then navigate to Applications -> Settings -> Session and Startup -> Sessions and click the Clear saved sessions button.

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.

Default 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.

Sound

Xfce4 mixer

Note: Xfce4 mixer and Xfce4 volumed are no longer being maintained upstream as they cannot be ported to GStreamer 1.0. For more information, see the 4.12 news post.

Xfce4 mixer, provided by xfce4-mixer, is the GUI mixer app and panel plugin from the Xfce team. It is part of the xfce4 group. For PulseAudio and OSS support, you will need to install gstreamer0.10-good-plugins if it is not installed already.

You might need to change the default sound card for Xfce4 mixer to function correctly. For further details, such as how to set the default sound card, see Advanced Linux Sound Architecture#Set the default sound card. Alternatively you can use PulseAudio together with pavucontrol or OSS. For OSS, see OSS#Applications that use GStreamer.

If you did need to change the default soundcard, logout to ensure that the changes take effect.

Change default sound card in Xfce4 mixer

In some cases (when using PulseAudio or xfce4-volumedAUR for instance) it might be necessary to change the default sound card in Xfce4 Mixer in order for volume control to work as expected. [2]

To change the default sound card, open xfce4-settings-editor and navigate to xfce4-mixer and check the entries under sound-cards. Locate the correct entry for the card you are using and then replace the values of sound-card and active-card with the entry. If you are using PulseAudio then the entry will likely be similar to the following: PlaybackInternalAudioAnalogStereoPulseAudioMixer. Then logout for the changes to take effect.

xfce4-alsa-plugin

If you do not use PulseAudio, you can install xfce4-alsa-pluginAUR. It provides a simple panel plugin with the ability to control ALSA volume, though it does not support keyboard volume buttons.

Keyboard volume buttons

If the xfce4-mixer package is version 4.10.0-3 or greater, then the mixer panel applet provides the ability to control the volume using the keyboard. However, volume notifications will not be shown. Alternatively, xfce4-volumedAUR maps volume keys to Xfce4 mixer, and displays notifications through Xfce4-notifyd. If you are using PulseAudio and you do not wish to use Xfce4 Mixer at all, install xfce4-pulseaudio-pluginAUR. This provides a panel applet which has support for keyboard volume control and volume notifications.

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-polkit-gitAUR.

Display blanking

Note: There are some issues associated with blanking and resuming from blanking in some configurations. See [3][4].

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 will control blanking and DPMS settings. These settings can be configured by running xfce4-power-manager-settings and clicking the Display tab. Note that unticking the Handle display power management option means that the Power Manager will disable DPMS - it does not mean that the Power Manager will relinquish control of DPMS. Also note that it will not disable screen blanking. 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

Tango-view-refresh-red.pngThis article or section is out of date.Tango-view-refresh-red.png

Reason: With xfce4-power-manager>1.5.1 the issue described below should in theory no longer apply. [5] (Discuss in Talk:Xfce#)

See XScreenSaver#DPMS and blanking settings. Note that if XScreenSaver is running alongside Xfce Power Manager, it may not be entirely clear which application is in control of blanking and DPMS as both applications 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 film for instance), it is advisable to disable blanking and DPMS through both applications.

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.

Tips and tricks

Hide partitions from thunar and xfdesktop

See Udisks#Hide selected partitions.

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 color 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
ColorPalette3=#4e4e9a9a0606
ColorPalette4=#c4c4a0a00000
ColorPalette5=#34346565a4a4
ColorPalette6=#757550507b7b
ColorPalette7=#060698989a9a
ColorPalette8=#d3d3d7d7cfcf
ColorPalette9=#555557575353
ColorPalette10=#efef29292929
ColorPalette11=#8a8ae2e23434

ColorPalette13=#72729f9fcfcf
ColorPalette14=#adad7f7fa8a8
ColorPalette15=#3434e2e2e2e2
ColorPalette16=#eeeeeeeeecec

Colour management

Xfce has no native support for colour management. [6] See ICC profiles for alternatives.

Multiple monitors

As of xfce4-settings version 4.11.4, 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 Manager in Xfce's settings. This will also disable gpg-agent and ssh-agent.

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"

Troubleshooting

Action buttons are missing icons

This happens if icons for some actions (Suspend, Hibernate) are missing from the icon theme, or do not have the expected names. To fix this, install an icon theme which has the necessary icons already added; see Icons#Xfce icons.

Then, you can switch to that icon theme using Applications -> Settings -> Appearance -> Icons.

Alternatively you can use the required icons provided by the icon theme you installed in your current icon theme. To do so, you first need to find out what the currently used icon theme is called. You can do so by using the command below:

$ xfconf-query -c xsettings -p /Net/IconThemeName

Then set the following variable:

$ icontheme=/usr/share/icons/theme-name

where theme-name is the name of the current icon theme.

Then create symbolic links from the current icon theme into the icon theme providing the icons (this example assumes the icons are being provided by the elementary-xfce-iconsAUR theme.)

ln -s /usr/share/icons/elementary-xfce/apps/16/system-suspend.svg           ${icontheme}/16x16/actions/system-suspend.svg
ln -s /usr/share/icons/elementary-xfce/apps/16/system-suspend-hibernate.svg ${icontheme}/16x16/actions/system-hibernate.svg
ln -s /usr/share/icons/elementary-xfce/apps/22/system-suspend.svg           ${icontheme}/22x22/actions/system-suspend.svg
ln -s /usr/share/icons/elementary-xfce/apps/22/system-suspend-hibernate.svg ${icontheme}/22x22/actions/system-hibernate.svg
ln -s /usr/share/icons/elementary-xfce/apps/24/system-suspend.svg           ${icontheme}/24x24/actions/system-suspend.svg
ln -s /usr/share/icons/elementary-xfce/apps/24/system-suspend-hibernate.svg ${icontheme}/24x24/actions/system-hibernate.svg
ln -s /usr/share/icons/elementary-xfce/apps/48/system-suspend.svg           ${icontheme}/48x48/actions/system-suspend.svg
ln -s /usr/share/icons/elementary-xfce/apps/48/system-suspend-hibernate.svg ${icontheme}/48x48/actions/system-hibernate.svg

Log out and in again, and you should see icons for all actions.

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

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

Keyboard settings are not saved in xkb-plugin

There is a bug in xfce4-xkb-plugin 0.5.4.1-1 which causes it to lose keyboard, layout switching and compose key settings. [7] As a workaround, enable Use system defaults in xfce4-keyboard-settings, then reconfigure xfce4-xkb-plugin.

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. [8]

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, logind handles the lid close event. To change this behavior so that the 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 that each time the laptop lid settings are changed in the power manager, this setting will be reset.

Rendering issues with Adwaita theme

Since the upgrade of gnome-themes-standard from 3.18.0-1 version to 3.20.0-1 the Adwaita theme exhibits several issues when being used in Xfce, like a frame around the notification area and dark background of the tooltip in eclipse.

A ugly solution is to downgrade the gnome-themes-standard to the old 3.18.0-1 meanwhile. The package can be downloaded at:

$ wget https://archive.archlinux.org/repos/2016/04/08/extra/os/$(uname -m)/gnome-themes-standard-3.18.0-1-$(uname -m).pkg.tar.xz

and installed via pacman's -U option.
