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)

Installation

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

Running sxlock

Simply invoking the sxlock command starts the display locker with default settings.

Custom settings:

-f <font description>: modify the font.
-p <password characters>: modify the characters displayed when the user enters his password. This can be a sequence of characters to create a fake password.
-u <username>: a user name to be displayed at the lock screen.
-l : Hide password length when typing

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:
