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.

Features

• 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)

Requirements

• libX11 (Xlib headers)

• libXext (X11 extensions library, for DPMS)

• libXrandr (RandR support)

• PAM

• giblib

• imlib2

Installation

Arch Linux users can install this package from the AUR.

For manual installation just install dependencies, checkout and make:

git clone https://github.com/ktravis/sxlock
cd ./sxlock
make
./sxlock

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
Before=sleep.target

[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.
