Screensaver/Locker

General#

LXQt does not provide its own screensaver or screen locker but any arbitrary screensaver/locker can be used.

In LXQt in order to use the checkbox in LXQt Session Settings, lock actions from the leave-menu, panel's application menus or lxqt-runner and also lock actions configured in lxqt-config-powermanagement a screensaver/locker has to be installed.

With LXQt 2.1 and later a custom screensaver can be added in "Session Settings" for both X11 and Wayland sessions.

Configuration#

Locking before suspend and hibernate can be set in LXQt Session Settings. Sometimes configuring a delay is needed when the screen is visible for a short time after resume.

Locking when idle or on laptop lid closure can be configured in Main menu → Settings → LXQt Settings → Power Management.

X11#

A xdg-screensaver compliant screensaver works automatically under X11, but also other custom screensavers/lockers can be set in "Session Settings".

xdg-screensaver 1.1.3 supports the following screensavers:

  • XScreenSaver
  • Xautolock
  • Gnome-screensaver
  • Mate-screensaver
  • Cinnamon-screensaver

Note that the latter three will install many GTK+ dependencies.

A list of available screen-lockers can be found here.

XScreenSaver#

XScreenSaver can be configured in Main menu → Settings → Screensaver.

Other Screenlockers using Xautolock#

Xautolock provides autolocking when idle and can be configured to use any installed screenlocker. Please refer to man xautolock for more details about possible configurations. Default timeout for idle is 10min.

A basic setup consists in adding in LXQt Session Settings under the "Autostart" section a command like xautolock -locker i3lock.

A custom screenlocker can be set manually in ~/.config/lxqt/lxqt.conf in versions prior to LXQt 2.1:

[Screensaver]
lock_command=xsecurelock

Wayland#

Working screenlockers are swaylock, hyprlock and waylock, not all compositors support all of them.

Note

Under kwin_wayland loginctl lock-session has to be used in "Session Settings" to trigger its built-in screensaver. Disabling the screensaver in KDE's systemsettings is recommended as both settings will trigger it.
