Xfce is a lightweight and
modular desktop environment currently based on GTK 3. To provide a complete user
experience, it includes a window manager, a file manager, desktop and panel.
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.
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.
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 alternative 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).
Set keyboard shortcut to launch
whisker menu
To set a keyboard
shortcut to launch the whisker menu, go to Settings > Keyboard and then the Applications
shortcut tab. Click on the Add button, set the command to xfce4-popup-whiskermenu and assign the desired
keyboard shortcut.
A number of graphical
tools are available for this task:
·

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.
Set preferred applications
To change the default
applications used for opening certain resources, use exo-preferred-applications. This will change the behavior of exo-open, which is invoked by resource
openers such as xdg-open.
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"
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.
Open xfce4-settings-editor and create a new property with
the following settings:
Property: /backdrop/screen0/xinerama-stretch
Type: Boolean
Value: TRUE|1|Enabled
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.
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 name.desktop 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"
xflock4 is the reference Bash script
which is used to lock an Xfce session.
It tries to lock the
screen with either xfce4-screensaver (also part of xfce4-goodies), xscreensaver, gnome-screensaverAUR, slock or xlockmore. It consecutively looks for the corresponding binary or exits with return
code 1 if it fails to find any of these.
The List of
applications/Security#Screen lockers contains a short description of these screen lockers together with
other popular applications. There is in this list an alternative locker, light-locker, which integrates particularly well
with xfce4-power-manager. Once it is 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. In this new GUI it is possible to set 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 five cited above, one must set LockCommand in the session's xfconf
channel to the command line to be used (the command inside the quotes in the following example can be adapted
accordingly for other screen lockers):
$ xfconf-query --create -c xfce4-session -p /general/LockCommand -t string -s "light-locker-command --lock"
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.
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 --create -c xfce4-power-manager -p /xfce4-power-manager/logind-handle-suspend-key -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 xfsettingsd
$ xfconf-query -c xfce4-session -p /sessions/Failsafe/Client1_Command -t string -sa wm_name
If you want to start the
window manager with command line options, see the commands below:
$ xfconf-query -c xfce4-session -p /sessions/Failsafe/Client0_Command -t string -sa xfsettingsd
$ xfconf-query -c xfce4-session -p /sessions/Failsafe/Client1_Command -t string -s wm_name -t string -s --wm-option
If you need more command
line options, simply add more -t string and -s --wm-option arguments to the command.
Note: If you instead set Client0_Command to wm_name and Client1_Command to xfsettingsd, you can prevent xfce4-session-logout from reverting to a default theme. However, you will need to manually set the cursor theme.
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.
XFCE themes are
available at xfce-look.org. Xfwm themes are stored in /usr/share/themes/theme_name/xfwm4, and set in Settings > Window Manager. GTK themes are
stored in /usr/share/themes/theme_name/gtk-2.0 and /usr/share/themes/theme_name/gtk-3.0 and 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.
Consistent Look Between SSD and CSD
Windows
Xfce currently uses
Server-Side Decorations (SSD) (see Window decoration) themed by Xfwm for most windows and Client-side decoration (CSD) themed by the respective programs for Xfce Settings, Print, Save, and other dialogs.
Xfwm SSD window styles
can be themed to match the CSD windows by manually adjusting or creating themes
in /usr/share/themes/theme_name/xfwm4 or by using a tool such as
the Xfwm4 Theme Generator which "Creates xfwm4 themes
from client side decorations."
Reverting Client-Side Decorations
To remove most CSD from
Xfce, install libxfce4ui-nocsdAUR and set
$ xfconf-query -c xsettings -p /Gtk/DialogsUseHeader -s false
This will move the Save
button to the bottom of the window in Save dialogs and do the same for Print dialogs. Xfce Settings dialogs will be
reverted to SSD. Programs such as Catfish will still have CSD.
To force SSD on all
windows, try gtk3-nocsd-gitAUR. Be sure to read all the
instructions on the project page.
Sound themes
XFCE4 supports freedesktop
system sounds, but it is not configured out of the box.
To enable a sound theme:
1.
Install libcanberra for PulseAudio support;
2.
"canberra-gtk-module" should be in the GTK_MODULES environment variable (re-login may be required);
3.
Check "Enable event
sounds" in Settings Manager → Appearance → Settings tab;
4.
In the Settings Editor set
"xsettings/Net/SoundThemeName" to a sound theme located in /usr/share/sounds/;
5.
Turn on "System Sounds" in
audio mixer (e.g. pavucontrol).
sound-theme-freedesktop provides a compatible sound
theme, but it lacks many required events. A better choice is sound-theme-smoothAUR (SoundThemeName should be "Smooth").
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 pasystray at the same time for a finer control.
Alternatively, xfce4-mixerAUR 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.
After installing the
panels, you have to add it to the taskbar or the keyboard shortcuts will not work.
For non desktop
environment specific alternatives, see List of applications/Multimedia#Volume control.
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.
·
ALSA: see Advanced Linux Sound Architecture#Keyboard volume control.
·
PulseAudio: see PulseAudio#Keyboard volume control
·
OSS: see OSS#Using multimedia keys with OSS[broken link: invalid section].
Keyboard shortcuts are
defined in two places: Settings > Window Manager > Keyboard, and Settings > Keyboard > Shortcuts.
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.
Some programs that are
commonly used with Xfce will control monitor blanking and DPMS (monitor powersaving) settings. They are discussed below.
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.
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.
If neither of the above
applications are running, then blanking and DPMS settings can be controlled using the xset command, see DPMS#Modify DPMS and screensaver settings with a command.
Note: There are some issues associated with blanking and resuming from
blanking in some configurations. See [1][2].
If plugged external
drives does not appear and installation partitions are shown as mounted devices, on the desktop and in Thunar, install gvfs. See Udisks#Hide selected partitions and Thunar#Automounting of large external
drives for more advanced
configuration options.
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 xfce4-screenshooter(1) for other optional arguments.
Alternatively, an independent screenshot program
like scrot can be used.
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 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:

MiscMiddleClickOpensUri=TRUE
env-modulesAUR and env-modules-tclAUR packages provide shell
autocompletion for login shell. However, by default sessions in xfce4-terminal are not considered as login. To enable autocompletion for
Environment Modules tick corresponding checkbox in Preferences or
just change CommandLoginShell to TRUE in ~/.config/xfce4/terminal/terminalrc.
Xfce has no native
support for colour management. [3] See ICC profiles for alternatives.
Xfce has support for
multiple monitors. Settings can be configured in the Applications > Settings > Display dialog.
In the Advanced tab
one can save profiles for different monitors and have them applied automatically
as soon as the connected monitors change.
For more information, see the display article
from the Xfce documentation.
Alternatively one can
use arandr to easily manage display configurations in the form
of xrandr commands which can be assigned to XFCE keyboard shortcuts.
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.

Go to Main Menu > Settings > Window Manager Tweaks > Accessibility tab. Uncheck Raise windows when any mouse button is pressed.
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"
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.
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.
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.
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
The Super key is treated
as a modifier key, like Ctrl and Alt, instead of producing a keypress. Assigning an action to it will keep you from using it for other shortcuts, because it will trigger that action
in addition to whatever else you assign to it.
To get around this, and make it more useful for
shortcuts, install the application xcape. This lets you configure modifier keys to act as other keys when pressed
and released on their own.
Next, go to Settings > Keyboard >
Application Shortcuts and assign an unused key combination, say Alt-F1, to the Application menu (or whatever action you want when you press the Super key by itself). Test that it works. Next, use xcape to assign Alt-F1 to the Super key:
$ xcape -e 'Super_L=Alt_L|F1'
Check that the Super key
now performs the action you assigned to Alt-F1.
If all is well, make this an autostart action ; go to Settings > Session and
Startup > Application
Autostart tab, press the Add button and enter the command there to make it run every time
you start Xfce (if xcape was already installed, also check that there is not already a similar entry registered).
Now, you can freely use the Super key in
shortcuts. For example: In Window Manager >
Keyboard, you can use Super and the up and down arrow keys for Raise window and
Lower window.
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.
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.
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
If you are running a
separate Xsettings daemon, it may make some configuration not taking effect. Disable it by removing or
commenting the corresponding line and restart Xorg.
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.
Using NVIDIA, multiple monitors and NVIDIA/Troubleshooting#Avoid screen tearing may result as a black screen
when booting Xfce. The screens' position conflict into the files /etc/X11/xorg.conf and ~/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml. Deleting the displays.xml file fixes the behavior.
$ rm ~/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml

Preferred Applications preferences
have no effect
The factual accuracy of this article or section is disputed.
Reason: xorg-xprop should only be needed to
activate the classic fallback, a "last effort" attempt at detecting Xfce. This should be fixable by
setting XDG_CURRENT_DESKTOP=XFCE [sic], if modern Xfce does not already do
so. (Discuss in Talk:Xfce)
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.
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.
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 is not 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 could also be the 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.
Install ttf-droid and ttf-dejavu. See also FS#44382.
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.
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.

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 the related forum topic.
Ensure the systemwide
XDG cursor is set to your desired cursor theme—see Cursor themes#XDG specification.
Run the following to
make it visible:
$ gsettings set org.xfce.mousepad.preferences.window menubar-visible true
Trash requires the
optional dependency gvfs to work. Install gvfs and reboot the system.
Delete ~/.cache/sessions by running:
$ rm -rf ~/.cache/sessions
Restart Xfce afterwards.
