Bug#690794: [wheezy] Fails to read EDID, results in bad monitor flickering
Verified problem does still exist with linux-image-3.5-trunk-amd64
from experimental.
$ uname -a
Linux dancer 3.5-trunk-amd64 #1 SMP Debian 3.5.5-1~experimental.1 x86_64 GNU/Linux
I'm still seeing flickering.
gnome-control-center still says the display is "Unknown".
