Ubuntu Oneric dmesg output, not having this problem
Debian bug: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=690794
Ubuntu bug, possibly the same, fixed, but I don't know how:
https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/958439
Installed Debian Wheezy, then installed package linux-image-3.5-trunk-amd64
from Experimental, which I guess is an unmodified mainline kernel:
$ uname -a
Linux dancer 3.5-trunk-amd64 #1 SMP Debian 3.5.5-1~experimental.1 x86_64
GNU/Linux
EDID is not read properly, resulting in (CRT) monitor flickering (looks like
60hz).
gnome-control-center says the display is "Unknown".
xrandr --verbose does not mention the EDID.
I previously had these problems on Ubuntu, reported in the above Ubuntu bug.
It persisted when I changed video cards from Nvidia to AMD Radeon. It went
away with a kernel upgrade. Not sure what the change was.
