Bug#405760: gdm: Same problem here when trying to switch from XDM to GDM but squares remain in Gnome -> unusable

[Axel K. Stammler]

Package: gdm
Version: 2.16.4-1
Followup-For: Bug #405760

I installed GDM and Gnome &c. and switched from XDM to GDM by running
'dpkg-reconfigure gdm' and setting GDM as default manager. After
crashing for a long time, GDM only showed squares. Earlier I had tried
Gnome with the same effect, so I just switched back to XDM. Seems I am
stuck with Fvwm :-(
