Installation
Install the xscreensaver package.
For an Arch Linux branded experience, install the xscreensaver-arch-logoAUR package.
Configuration
Most options are configured on a user-by-user basis by running xscreensaver-demo. xscreensaver-demo writes the chosen configuration to ~/.xscreensaver
, discarding any manual modifications to the file. Global options are defined in /usr/share/X11/app-defaults/XScreenSaver
.
Since at least XScreenSaver 5.22, there is another way to edit XScreenSaver's user configuration, using Xresources. This includes theming support. See [1] for the version 5.22 defaults.
DPMS and blanking settings
This article or section needs language, wiki syntax or style improvements.
xset s 0 0
, uses its own timer for the various animations, but sets the DPMS timeout to the values in Display Power Management (Discuss in Talk:XScreenSaver#)XScreenSaver manages screen blanking and display energy saving (DPMS) independently of X itself and overrides it. To configure the timings for blanking, standby, display poweroff and such, use xscreensaver-demo or edit the configuration file manually, e.g. ~/.xscreensaver
:
timeout: 1:00:00
cycle: 0:05:00
lock: False
lockTimeout: 0:00:00
passwdTimeout: 0:00:30
fade: True
unfade: False
fadeSeconds: 0:00:03
fadeTicks: 20
dpmsEnabled: True
dpmsStandby: 2:00:00
dpmsSuspend: 2:00:00
dpmsOff: 4:00:00
DPMS and screen blanking can be disabled by starting xscreensaver-demo and, for the Mode setting, choosing Disable Screen Saver.
Usage
-no-splash
switch. See man xscreensaver
for a full list of options.In the Xfce, LXDE and LXQt environments, XScreenSaver is autostarted automatically if it is available - no further action is required. For other environments, see Autostarting.
To immediately trigger xscreensaver
, if it is running, and lock the screen, execute the following command:
$ xscreensaver-command --lock
Lock on suspend
See Power management#xss-lock. You may want to set XScreenSaver's fade out time to 0.
User switching from the lock screen
By default, XScreenSaver's New Login button in the lock screen will call /usr/bin/gdmflexiserver
to switch users. Other display managers than GDM or KDM that support user switching (such as LightDM) require a different command.
~/.Xresources
whilst leaving the argument blank will make the New Login button disappear.As modifications in ~/.xscreensaver
are discarded by xscreensaver-demo, ~/.Xresources
is used in this section.
LXDM
To use LXDM's switching mode:
xscreensaver.newLoginCommand: lxdm -c USER_SWITCH
LightDM
To use LightDM's switching mode:
xscreensaver.newLoginCommand: dm-tool switch-to-greeter
Tips and tricks
Disable during media playback
mplayer/mpv
Add the following to ~/.mplayer/config
or ~/.mpv/config
:
heartbeat-cmd="xscreensaver-command -deactivate >&- 2>&- &"
Kodi
Kodi has no native support to disable XScreenSaver (it uses its own screensaver). Install the kodi-prevent-xscreensaverAUR package as a workaround.
Flash
There is no native way to disable XScreenSaver for Flash, but there is script named lightsOn with support for Firefox's Flash plugin, Chromium's Flash plugin, MPlayer, and VLC.
Animated wallpaper
One can run xscreensaver
in the background, just like a wallpaper. First, kill any process that is controlling the background (the root window).
Then, locate the desired XScreenSaver executable (typically in /usr/lib/xscreensaver/
) and run it with the -root
flag, for example:
$ /usr/lib/xscreensaver/glslideshow -root &
$ xwinwrap -b -fs -sp -fs -nf -ov -- /usr/lib/xscreensaver/glslideshow -root -window-id WID &
Troubleshooting
You can configure xscreensaver to write to a log file by creating the logfile # touch /var/log/xscreensaver.log
and then specifying its X resource logFile.
~/.Xresources
xscreensaver.logFile:/var/log/xscreensaver.log
To log verbose debugging information to the logFile as well start xscreensaver with the -verbose
command line option, or add this to ~/.Xresources
~/.Xresources
xscreensaver.logFile:/var/log/xscreensaver.log
xscreensaver.verbose:true
