The ArchLinux Workstations are themed with either the ACM Logo or LUG logo. They are set to alternate between workstations.
Setup the ACM custom repo on the workstation first
Install themes with this command and follow the post install instructions
pacman -S acm-lug-lxdm-themes
Unpack this archive with the ACM and LUG themes into /usr/share/lxdm/themes
This is setup by three files:
LoginReady - This is exicuted as root when LXDM is ready to show the screen.
PreLogin - Executed by LXDM as root.
SetLogo - Contains the sed regex for the link and IP, the 'even' and 'odd' themes settings, and detects which theme to use.
Up to date as of September 19, 2014.
