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===
+
See [[Xdg-menu]] for more info on using the Free Desktop menu system.
There are two methods to start Xfce (and in fact, any desktop or window manager) at boot time:
 
  
* Run Xfce through a Display Manager
+
==== Whisker menu ====
* Run Xfce automatically using [[Bash#Configuration_file_overview|bash_profile]] or [[inittab]]
 
  
See [[Display Manager]] for details about installing and configuring a Display Manager (be sure to configure it properly for [[PolicyKit]]). See [[Start X at Boot]] for configuration instructions on using bash_profile or inittab.
+
{{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'...).
  
===Manually===
+
==== Edit entries ====
  
You can execute:
+
A number of graphical tools are available for this task:
$ startxfce4
 
from the console, or configure [[xinitrc]] and use xinit or startx.
 
  
If you have not created a {{ic|~/.xinitrc}} yet, do so with:
+
* {{App|MenuLibre|An advanced menu editor that provides modern features in a clean, easy-to-use interface.|https://launchpad.net/menulibre|{{AUR|menulibre}}}}.
 +
* {{App|Alacarte|Menu editor for GNOME|http://www.gnome.org/|{{Pkg|alacarte}}}}
 +
* {{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}}}}
  
$ cp /etc/skel/.xinitrc ~/.xinitrc
+
Alternatively, create the file {{ic|~/.config/menus/xfce-applications.menu}} manually. See the example configuration below:
  
and add the following line:
+
<!DOCTYPE Menu PUBLIC "-//freedesktop//DTD Menu 1.0//EN"
 +
  "http://www.freedesktop.org/standards/menu-spec/1.0/menu.dtd">

The {{ic|<MergeFile>}} tag includes the default Xfce menu.
  
Example:

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.
{{hc|~/.xinitrc|<nowiki>#!/bin/sh
 
  
if [ -d /etc/X11/xinit/xinitrc.d ]; then
+
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].
  for f in /etc/X11/xinit/xinitrc.d/*; do
 
    [ -x "$f" ] && . "$f"
 
  done
 
  unset f
 
fi
 
  
exec startxfce4 --with-ck-launch</nowiki>}}
+
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]].
  
{{Note|
+
=== Desktop ===
*{{ic|--with-ck-launch}} starts a clean ConsoleKit session needed by Xfce for power management, automounting, shutting down, rebooting, etc. ConsoleKit/PolicyKit capable display managers such as gdm do this for you automatically and thus the command does not need to be specified seperatly.
 
*{{pkg|xorg-xdm}} is also ConsoleKit/PolicyKit capable since version 1.1.11. Unless you happen to run an old version, you must '''not''' use {{ic|--with-ck-launch}} from your .xinitrc or .xsession for xdm.
 
*[[SLiM]] is also ConsoleKit capable since version 1.3.3.  Unless you happen to run an old version, you must '''not''' use {{ic|--with-ck-launch}} from your .xinitrc or slim.conf login_cmd.
 
*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.
 
*If you are running an Xfce older than 4.10, you will have to use {{ic|exec ck-launch-session startxfce4}}
 
}}
 
{{Note|{{ic|dbus-launch}} should actually be called '''after''' launching ConsoleKit, otherwise there will be authorization problems when mounting disks as a regular user, see {{Bug|25031}}. For a '''temporary''' workaround you can edit the {{ic|xinitrc.d}} script at the beginning of the file as follows, and '''keep an eye on the evolution of the bug report''' (and possibly vote it):
 
{{hc|~/.xinitrc [temporary workaround]|<nowiki>#!/bin/sh
 
  
if [ -d /etc/X11/xinit/xinitrc.d ]; then
+
==== Transparent background for icon titles ====
  for f in /etc/X11/xinit/xinitrc.d/*; do
 
    # Do not launch dbus before ConsoleKit (FS#25031)
 
    #[ -x "$f" ] && . "$f"
 
    [ "$f" != "/etc/X11/xinit/xinitrc.d/30-dbus" ] && [ -x "$f" ] && . "$f"
 
  done
 
  unset f
 
fi
 
  
exec startxfce4 --with-ck-launch</nowiki>}}
+
To change the default white background of desktop icon titles to something more suitable, create or edit {{ic|~/.gtkrc-2.0}}:
There is still no need to start {{ic|dbus-launch}} explicitly since {{ic|startxfce4}} takes care of doing that anyway.}}

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 systemd-sysvcompat corrects this misbehavior.

do {{ic|pacman -Sy  systemd-sysvcompat}} as root and it should work right away.

==Tips and tricks==
+
==== Remove desktop icons ====
===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 ====
+
Issue the following command:
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.
+
$ xfconf-query -c xfce4-desktop -v --create -p /desktop-icons/style -t int -s 0
  
====How to remove menu entries from the System menu====
+
To reinstate icons on the desktop, issue the same command with a value of 2.
===== 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 =====
+
==== One wallpaper across multihead ====
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.
+
Open {{ic|xfce4-settings-editor}} and create a new property with the following settings:
  
===== Method 3 =====
+
Property: /backdrop/screen0/xinerama-stretch
The third method is the '''cleanest''' and recommended in the [http://wiki.xfce.org/howto/customize-menu Xfce wiki].
+
Type: Boolean
 +
Value: TRUE|1|Enabled
  
Create the file {{ic|~/.config/menus/xfce-applications.menu}} and copy the following in it:
+
==== Kill window shortcut ====
{{bc|<nowiki>
 
<!DOCTYPE Menu PUBLIC "-//freedesktop//DTD Menu 1.0//EN"
 
  "http://www.freedesktop.org/standards/menu-spec/1.0/menu.dtd">

    <MergeFile type="parent">/etc/xdg/menus/xfce-applications.menu</MergeFile>
 
  
    <Exclude>
+
With {{Pkg|xorg-xkill}}, use {{ic|xkill}} to interactively kill a window. For the currently active window, use {{Pkg|xdotool}}:
        <Filename>xfce4-run.desktop</Filename>
 
  
        <Filename>exo-terminal-emulator.desktop</Filename>
+
$ xdotool getwindowfocus windowkill

</Menu>
+
==== Autostart ====
</nowiki>}}
 
  
The {{ic|<MergeFile>}} tag includes the default Xfce menu in our file. This is important.
+
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.
  
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.
+
Autostart applications are stored as ''.desktop'' files in ''~/.config/autostart/''.
  
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.
+
Alternatively, add the commands you wish to run (including setting environment variables) to [[xinitrc]] (or [[xprofile]] when a [[display manager]] is being used).
  
===== Method 4 =====
+
{{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''"}}
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)? ====
+
==== Lock the screen ====
I have found some shortcuts that show in the category “Other” in this directory:
+
''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.
{{ic|~/.local/share/applications/wine/}}.
 
  
====Panel autohide delay====
+
The [[List of applications/Security#Screen lockers]] contains a short description of these four screen lockers together with other popular applications.
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====
+
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.
  
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.
+
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 {{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}}.
  
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}}).
+
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.
  
#!/bin/bash
+
==== Suspend ====
set -e
+
Whenever asked to suspend, Xfce executes the {{man|1|xfce4-session-logout}} command with the {{ic|suspend}} option:
 
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
 
  
 +
$ xfce4-session-logout --suspend
  
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.
+
Whether or not the session is systematically locked on ''suspend'' can be configured through the xfconf properties or from the 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)
+
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.
  
xfconf-query -c xfce4-panel -p /panels/panel-$ID/disable-struts -n -t bool -s true
+
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.
  
=== Desktop ===
+
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}}:
  
==== Use a transparent background for desktop icon titles ====
+
$ xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/logind-handle-suspend-key -n -t bool -s '''true'''
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|To check how ''systemd-logind'' handles events whenever it has precedence over Xfce, check {{man|5|logind.conf}}}}
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_IGNORE}="1"
+
==== Disable saved sessions ====
KERNEL=="sda2", ENV{UDISKS_IGNORE}="1"
 
  
Would show all partitions with the exception of sda1 and sda2 on your desktop.
+
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.
  
==== Switch to old desktop right click menu without Thunar things ====
+
{{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}}}}
xfconf-query -c xfce4-desktop -v --create -p /desktop-icons/style -t int -s 0
 
  
==== Adding the kill window shortcut ====
+
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:
  
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.
+
[xfce4-session]
 +
SaveSession=NONE
  
Create a script in {{ic|~/.config/xfce4/killwindow.sh}} with this content and make it executable (you can use {{ic|chmod 755 killwindow.sh}}).
+
If kiosk mode is not working, the user can set read only permissions for the sessions directory:
  
  xkill -id "`xprop -root -notype | sed -n '/^_NET_ACTIVE_WINDOW/ s/^.*# *\|\,.*$//g p'`"
+
  $ rm ~/.cache/sessions/* && chmod 500 ~/.cache/sessions
  
Now associate a shortcut using {{ic|Settings -> Keyboard}} to that script.
+
This will prevent Xfce from saving any sessions despite any configuration that specifies otherwise.
  
=== XFWM4 ===
+
==== Use a different window manager ====
==== 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
+
{{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.}}
  
==== Disable window roll-up ====
+
The files specifying the default window manager are found in the following locations:
xfconf-query -c xfwm4 -p /general/mousewheel_rollup -s false
+
*{{ic|~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-session.xml}} - per user
 +
*{{ic|/etc/xdg/xfce4/xfconf/xfce-perchannel-xml/xfce4-session.xml}} - systemwide
  
==== Disable/enable automatic resizing/tiling of windows at edge of screen ====
+
The default window manager for the user can be set easily using ''xfconf-query'':
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 xfce4-session -p /sessions/Failsafe/Client0_Command -t string -sa '''wm_name'''
  
  xfconf-query -c xfwm4 -p /general/tile_on_move -s false  # To disable
+
If you want to start the window manager with command line options, see the command below:
xfconf-query -c xfwm4 -p /general/tile_on_move -s true  # To enable
+
  $ 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.
  
=== Commands for the settings manager ===
+
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.
  
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:
+
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.

See also [[Cursor themes]], [[Icons]], and [[Font configuration]].
====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/}}
+
=== Sound ===
* 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====
+
==== Keyboard volume buttons ====
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 ====
+
{{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.
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===
+
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.
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
+
For non desktop environment specific alternatives, see [[List of applications#Volume managers]].
  
You could also need to install gvfs-afc (read [https://bbs.archlinux.org/viewtopic.php?pid=889018 this discussion]):
+
===== Shortcuts =====
  
# pacman -S gvfs-afc
+
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]].
  
It is also a good idea to install thunar-volman (included in the {{ic|xfce4-goodies}} group):
+
=== Keyboard Shortcuts ===
  
# pacman -S thunar-volman
+
Keyboard shortcuts are defined in two places: ''Settings > Window Manager > Keyboard'', and ''Settings > Keyboard > Shortcuts''.
  
Udisk and a udisk wrapper are recommended if you want to automount optical and external drives easily
+
=== Polkit Authentication Agent ===
  
* [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.
+
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]].
  
===How to add themes to XFCE===
+
A third party polkit authentication agent for Xfce is also available, see {{AUR|xfce-polkit}} or {{AUR|xfce-polkit-git}}.
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.
+
=== Display blanking ===
 +
Some programs that are commonly used with Xfce will control monitor blanking and [[DPMS]] (monitor powersaving) settings. They are discussed below.
  
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.
+
;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.
  
4. GTK theme is available here:
+
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.
Menu --> Settings --> Appearance
 
You select your xfwm theme in:
 
Menu --> Settings --> Window Manager
 
  
=== Cursors ===
+
;XScreenSaver
Main article: [[X11 Cursors]]
+
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]].
  
If you have alternative X cursor themes installed, Xfce can find them with:
+
;xset
Menu --> Settings --> Mouse --> Theme
+
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]].
  
=== Icons ===
+
{{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].}}
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}}.
+
== Tips and tricks ==
  
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).
+
=== Hide partitions from thunar and xfdesktop ===
  
Optional: run {{ic|gtk-update-icon-cache -f -t ~/.icons/<theme_name>}} to update icon cache
+
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.
  
4. Switch your icons by going to:
+
=== Screenshots ===
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.
+
Xfce has its own screenshot tool, {{pkg|xfce4-screenshooter}}. It is part of the {{grp|xfce4-goodies}} group.
  
=== Fonts ===
+
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.
  
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
+
Alternatively, an independent screenshot program like [[Taking a screenshot#scrot|scrot]] can be used.
  
You could also try using a custom DPI setting.
+
=== Disable Terminal F1 and F11 shortcuts ===
  
=== Sound ===
+
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.
  
==== Configuring xfce4-mixer ====
+
{{hc|~/.config/xfce4/terminal/accels.scm|
 +
(gtk_accel_path "<Actions>/terminal-window/fullscreen" "")
 +
(gtk_accel_path "<Actions>/terminal-window/contents" "")
 +
}}
  
{{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.
+
=== Terminal color themes or palettes ===
  
  GStreamer was unable to detect any sound devices. Some sound system specific GStreamer packages may be missing. It may also be a permissions problem.
+
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.
  
(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]].
+
==== Changing default color theme ====
  
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}}.
+
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.
  
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}}.
+

==== How do I get xfce4-mixer and OSS4 to work together? ====
+
==== Terminal tango color theme ====
  
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.
+
To switch to tango color theme, open with your favorite editor
  
  ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var \
+
~/.config/xfce4/terminal/terminalrc
    '''--enable-oss \'''
 
    --disable-static --enable-experimental \

    --disable-hal \
 
    --with-package-name="GStreamer Good Plugins (Archlinux)" \
 
    --with-package-origin="http://www.archlinux.org/"
 
  
and then run makepkg -i.
+
And add(replace) these lines:
  
  makepkg -i

=== 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.

=== Colour management ===
  
==== Change volume with keyboard volume buttons  ====
+
Xfce has no native support for colour management. [https://bugzilla.xfce.org/show_bug.cgi?id=8559] See [[ICC profiles]] for alternatives.
  
Go to
+
=== Multiple monitors ===
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 =====
+
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.
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:
+
=== SSH agents ===
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.
+
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:
  
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.
+
xfconf-query -c xfce4-session -p /startup/ssh-agent/enabled -n -t bool -s false
  
===== OSS =====
+
To force using ssh-agent even if gpg-agent is installed, run the following instead:
Use one of these scripts: http://www.opensound.com/wiki/index.php/Tips_And_Tricks#Using_multimedia_keys_with_OSS
 
  
If using ossvol (recommended), add:
+
  xfconf-query -c xfce4-session -p /startup/ssh-agent/type -n -t string -s ssh-agent
  ossvol -i 1
 
for the volume up button
 
ossvol -d 1
 
for the volume down button
 
ossvol -t
 
for the mute/unmute button
 
  
===== Xfce4-volumed =====
+
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.
  
[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.
+
Source: http://docs.xfce.org/xfce/xfce4-session/advanced
  
{{accuracy|reason=There should be a short explanation of what this does and why it fixes the issue (bug?).}}
+
=== Scroll a background window without shifting focus on it ===
  
If you use pulseaudio and xfce4-volumed unmute does not work, try this:
+
Go to ''Main Menu > Settings > Window Manager Tweaks > Accessibility'' tab.
 +
Uncheck ''Raise windows when any mouse button is pressed''.
  
$ xfconf-query -c xfce4-mixer -p /active-card -s `xfconf-query -c xfce4-mixer -p /sound-card`
+
=== Mouse button modifier ===
  
===== Volumeicon =====
+
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:
  
{{pkg|volumeicon}} is an alternative to xfce4-volumed in the community repo also handling keybindings and notifications through {{pkg|xfce4-notifyd}}.
+
$ xfconf-query -c xfwm4 -p /general/easy_click -n -t string -s "Super"
  
==== Adding startup/boot sound ====
+
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:
  
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:
+
$ xfconf-query -c xfwm4 -p /general/easy_click -n -t string -s "Ctrl><Alt"
  
aplay /boot/startupsound.wav
+
=== Set the two fingers click to middle click for a touchpad ===
  
The file location and filename can be whatever you want, but naming it descriptively and putting it in /boot keeps things tidy.
+
{{Style|Convoluted way of simply configuring [[Touchpad Synaptics]]}}
  
=== xdg-open integration (Preferred Applications) ===
+
If you want the 2 finger click on the touchpad to do a middle click, create or edit the following file:
  
Most applications rely on [[xdg-open]] for opening a preferred application for a given file or URL.
+
{{hc|~/.config/xfce4/xfconf/xfce-perchannel-xml/pointers.xml|<nowiki>
 
+
<channel name="pointers" version="1.0">
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.
+
  <property name="SynPS2_Synaptics_TouchPad" type="empty">
 
+
    <property name="Properties" type="empty">
If you do not do that, your preferred applications preferences (set by exo-preferred-applications) will not be obeyed.
+
      <property name="Synaptics_Tap_Action" type="array">
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.

        <value type="int" value="0"/>
 +
        <value type="int" value="0"/>
 +
        <value type="int" value="0"/>

        <value type="int" value="2"/>

        <value type="int" value="3"/>
 +
      </property>
 +
    </property>
 +
  </property>
 +
</channel>
 +
</nowiki>}}
  
To make sure xdg-open integration is working correctly, ask ''xdg-settings'' for the default web browser and see what the result is:
+
The 2 in the array is the middle click.
  
# xdg-settings get default-web-browser
+
=== 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.
  
If it replies with:
+
=== 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''.
  
xdg-settings: unknown desktop environment
+
Image editing programs like [[GIMP]] can be used to convert and scale your favourite images down to 96x96.
  
it means that it has failed to detect XFCE as your desktop environment, which is likely due to a missing {{Pkg|xorg-xprop}} package.
+
===  Power manager plugin label ===
  
=== Screenshots ===
+
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).
  
==== Using print-screen key ====
+
It is also accessible through the power manager plugin GUI in ''Properties > Show label''
  
A simple way is to use a command-line screenshot utility:
+
== Troubleshooting ==
  
# pacman -S scrot
+
=== Desktop icons rearrange themselves ===
  
Then go to:
+
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.
  
XFCE Menu  -->  Settings  -->  Keyboard  >>>  Application Shortcuts.
+
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:
  
Add the "scrot" command to use the "PrintScreen" key.
+
[Firefox]
 +
row=3
 +
col=0
  
All screenshots will be placed in your home folder with unique names (i.e. {{ic|2009-02-19-063052_1280x1024_scrot.png}}).
+
means that the Firefox icon will be located on the 4th row of the leftmost column.
  
====Screenshooter====
+
=== GTK themes not working with multiple monitors ===
  
There is also an a screenshot plugin for the Xfce panel, which can be used instead of scrot, that is available in extra:
+
{{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?}}
  
# pacman -S xfce4-screenshooter
+
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.
  
You can add a keyboard binding for it using the command
+
=== Icons do not appear in right-click menus ===
  
xfce4-screenshooter -f
+
{{Note|Despite the deprecation of GConf, this method does still work.}}
  
instead of "scrot". You will get a dialog window after pressing "Print" where you can copy the image to the clipboard or save it.
+
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:
  
=== Change mount options ===
+
$ gconftool-2 --type boolean --set /desktop/gnome/interface/buttons_have_icons true
 +
$ gconftool-2 --type boolean --set /desktop/gnome/interface/menus_have_icons true
  
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}}:
+
=== NVIDIA and xfce4-sensors-plugin ===
  
[vfat]
+
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}}.
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.
+
=== Panel applets keep being aligned on the left ===
  
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.
+
Add a separator someplace before the right end and set its "expand" property. [https://forums.linuxmint.com/viewtopic.php?f=110&t=155602}]
  
===Terminal tango color theme===
+
=== Preferred Applications preferences have no effect ===
Open with your favorite editor
 
  
~/.config/Terminal/terminalrc
+
Most applications rely on [[xdg-open]] for opening a preferred application for a given file or URL.
  
And add(replace) this lines:

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.

=== Colour management ===
+
To make sure xdg-open integration is working correctly, ask ''xdg-settings'' for the default web browser and see what the result is:
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 ====
+
# xdg-settings get default-web-browser
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.).
+
If it replies with:
  
See [[ICC_Profiles#Loading_ICC_Profiles]] for more information.
+
xdg-settings: unknown desktop environment
  
==== Creating a profile ====
+
it means that it has failed to detect Xfce as your desktop environment, which is likely due to a missing {{Pkg|xorg-xprop}} package.
  
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]].
+
=== Restore default settings ===
  
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"}}.
+
If for any reason you need to revert back: to the default settings, rename {{ic|~/.config/xfce4-session/}} and {{ic|~/.config/xfce4/}}
{{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.
+
$ mv ~/.config/xfce4-session/ ~/.config/xfce4-session-bak
 +
$ mv ~/.config/xfce4/ ~/.config/xfce4-bak
  
=== XDG User Directories ===
+
Relogin for changes to take effect. If you get {{ic|Unable to load a failsafe session}} upon login, see the [[#Session failure]] section.
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.

 +
* Errors reported by a [[display manager]] such as {{ic|No window manager registered on screen 0}}.
 +
* Unable to load a failsafe session:
  
== Troubleshooting ==
+
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.
  
=== Unable to open external windows partitions ===
+
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 external partitions like a fat32 drive connected via eSata, and launching them from the desktop results in a dialog telling you 'Authentication is required', you need to ensure polkit-gnome is installed and PolicyKit Authentication Agent is started by xfce4.
 
pacman -S polkit-gnome
 
Restart xfce4 and go:
 
Applications Menu > Settings > Sessions and Startup
 
Check that PolicyKit Authentication Agent is enabled under the Application Autostart tab.
 
  
=== xfce4-power-manager is not working ===
+
$ rm -r ~/.cache/sessions/
Check you have added dbus to the {{ic|DAEMONS}} array in {{ic|/etc/[[rc.conf]]}}.
 
  
=== Xfce4-xkb-plugin settings issue ===
+
Also make sure that the relevant folders in {{ic|$HOME}} are owned by the user starting {{ic|xfce4}}. See [[Chown]].
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 ===
+
=== Fonts in window title crashing xfce4-title ===
  
Thunar relies on '''Tumbler''' to generate thumbnails. You can install Tumbler by issuing
+
[[Install]] {{Pkg|ttf-droid}} and {{Pkg|ttf-dejavu}}. See also {{Bug|44382}}.
  
pacman -S tumbler
+
=== Laptop lid settings ignored ===
  
More details in [[Thunar#Thunar_Thumbnailers|Thunar's page]].
+
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
  
=== Locales ignored with GDM ===
+
{{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.}}
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 ===
+
=== User switching action button is greyed out ===
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
+
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].
$ mv ~/.config/xfce4/ ~/.config/xfce4-bak
 
  
Logout and login for changes to take effect.
+
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.
  
=== NVIDIA and xfce4-sensors-plugin ===
+
* For LXDM - [[LXDM#Simultaneous users and switching users]].
To detect and use sensors of nvidia gpu you need to install {{AUR|libxnvctrl}} and then recompile {{Pkg|xfce4-sensors-plugin}} package.
+
* For LightDM - [[LightDM#User switching]].
  
=== Session failure ===
+
=== Macros in .Xresources not working ===
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 ===
+
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].
  
This is due to a change in the Window Buttons panel plugin which no longer expands to fill the available space.
+
=== Cursor theme doesn't change on login ===
  
To emulate the old behavior, add a transparent separator between the window buttons and the clock/notification area, setting its expand property.
+
Ensure the systemwide XDG cursor is set to your desired cursor theme - see [[Cursor themes#XDG specification]].
 
 
=== Preferred Applications preferences have no effect ===
 
  
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]]

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">

<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 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.
