Description Philip Witte 2012-11-04 02:36:39 UTC 
As far as I can tell, Xorg-server 1.11 (only version I've tested) doesn't have the option "-seat" (Confirm by running "$ X -seat"). Also, as far as I know, Catalyst 12.6 (required for Radeon HD 4xxx cards and below) doesn't work with Xorg-server 1.12 and above, requiring Xorg 1.11. However, on systemd systems (like Arch Linux), GDM is starting X with the option "-seat" (see below for #line) which causes GDM to fail. So ATi owners with cards prior to HD 5xxx series cards looking to use Catalyst drivers and systemd currently can't use GDM 3.6.1

#line where "-seat" is added to X arguments:

THIS IS NOT A BUG. Turns out Catalyst 12.6 works fine with Xorg 1.12, which supports "-seat" argument. A simple upgrade to Xog 1.12 fixes the problems with GDM. Sorry for the misreport.

Whoops, forgot to mark RESOLVED/NOTABUG in my last message.
