sxlock - simple X screen locker
Simple screen locker utility for X, fork of sflock, which is based on slock. Main difference is that sxlock uses PAM authentication, so no suid is needed.
- provides basic user feedback
- uses PAM
- sets DPMS timeout to 10 seconds, before exit restores original settings
- basic RandR support (drawing centered on the primary output)
- libX11 (Xlib headers)
- libXext (X11 extensions library, for DPMS)
- libXrandr (RandR support)
Arch Linux users can install this package from the AUR.
For manual installation just install dependencies, checkout and make:
git clone git://github.com/lahwaacz/sxlock.git cd ./sxlock make ./sxlock
Simply invoking the sxlock command starts the display locker with default settings.
-f <font description>: modify the font. -c <password characters>: modify the characters displayed when the user enters his password. This can be a sequence of characters to create a fake password.
Hooking into systemd events
When using systemd, you can use the following service (create
/etc/systemd/system/sxlock.service) to let the system lock your X session on hibernation or suspend:
[Unit] Description=Lock X session using sxlock [Service] User=<username> Environment=DISPLAY=:0 ExecStart=/usr/bin/sxlock [Install] WantedBy=sleep.target
However, this approach is useful only for single-user systems, because there is no way to know which user is currently logged in. Use xss-lock as an alternative for multi-user systems.
