The outcome if this is that I now have GDM working on my X200 + external monitor, but not on the F2A85-M motherboard + external. For now I'm just using Slim on the radeon-based system, so I suppose this can be closed. I think this was two separate issues: 1. I think GDM stopped working on the X200 due to renumbered uid/gids that caused permission problems on /var/lib/gdm. Not 100% sure - was a day or two between when I removed /var/lib/gdm and reconfired and when I tried the external monitor on X200 again. 2. Starting GDM on the F2A85-M gives the following in /var/log/debug: May 2 12:19:12 localhost vmunix: [ 24.301185] [drm] radeon: 768M of VRAM memory ready May 2 12:19:12 localhost vmunix: [ 24.301237] [drm] radeon: 1024M of GTT memory ready.

I don't seem to have a /run/current-system/profile. I suppose it doesn't matter now since I've since done a `pull` and `system reconfigure`. Thanks!
