The ArchLinux Workstations are themed with either the ACM Logo or LUG logo. They are set to alternate between workstations.
I(clee231)(Chase Lee) have written a script to determine and switch the logos based on hostname.
Currently, the script is setup to run once before logging in the user as root. This means that there needs to be at least one login for the script to run.
This is setup by two files:
PreLogin - This calls the SetLogo script. Executed by LXDM as root.
SetLogo - Contains a set of all six workstation hostnames, and detects which theme to use.
