Bug#715508: gdm3: System settings → displays offers unusable screen resolutions

[Axel Stammler]

Package: gdm3
Version: 3.4.1-8
Severity: normal

Dear Maintainer,

if I connect a second display and try possible settings, I get very few resolutions to
choose from and they are all 4:3 resolutions even though the display is 16:9. I have tried
different displays and projectors. All of them worked perfectly under Squeeze.

Switching displays off and on again did not change this, and neither did clicking on
“Detect”. The effect was even worse if I tried mirroring (which I do not want). Then, even
for my Ee PC's native 16:9 screen all I got was a single 4:3 resolution (800×600).
