I just ran into this problem as well, and was about to report the same
workaround (changing /usr/bin/X11/xdm to /usr/bin/xdm in /etc/init.d/xdm
and /etc/X11/default-display-manager). But I'm still not sure which X
server to use in /etc/X11/xdm/Xservers. There's

The screen flickering has returned after aptitude upgrading a few days
ago. It happens every few minutes.
The upgrade switched to these xserver-xorg packages:
xserver-xorg-core 2:1.6.3-1
xserver-xorg-video-intel 2:2.8.0-2
The hardware is a TP T60 with Intel graphics. From lspci:

The flickering seems absent since this morning, when I installed and
rebooted with the latest and greatest 2.6.30 kernel package
(linux-image-2.6.30-1-686 version 2.6.30-5).

2.7.1 also fixed other hangs I often noticed with 2.7.0. The fix was

This could fix any number of cases where the

it down.

After about a day of uptime, the X server suddenly crashed; xdm tried
to restart it but the server kept crashing. Restarting xdm didn't
help, but rebooting did.

I'm pretty certain that what you're seeing is already reported upstream:

I just read through that thread. It looks similar but I'm not too sure.
The reports there were of the whole display blanking for a (short)
while. Mine doesn't go blank.
I'm using the intel driver from the experimental repo on a system
otherwise using unstable without any ill effects. The problem is that
even the experimental version is too old (2.6.1). Upstream has had a
large number of bug fixes since then (most importantly to me - XV

Great, that's a much simpler recipe. I did that and restarted the X

Not sure it's going to help, but well, having an updated bug status
would be nice.
For a week or so I've been running xserver-xorg-video-intel
2.12.0+shadow-2 (and shadow-1 for a week before that). Good news: The

The flickering in #56 has returned since I upgraded the X server
and kernel a couple days ago (I'm tracking 'unstable'). Now it
flickers a once or twice per minute.
In addition, one of the Firefox windows often gets
At least the flickering and 'screen turns to pink' issues are a kernel
bug (or multiple kernel bugs). Adding i915.powersave=0 to the kernel
command line should work around that.
Thanks. That fixed the pink screen and the flickering (and the 'tearing').

Downgrading xserver-xorg-video-intel to 2.13.0-3 solved the same problem
for me (Thinkpad T60 with Intel 945GM graphics). I suspected that it
would work based on the Debian Changelog entry for 2.13.0-4:

Alas, yes: I still see the problem. It happens every couple days where

started filling out a new Debian bug report, but then got the hang

I see you're running 2.6.37, and it looks like there were some more

backlight. However, my backlight is fine: It turns off upon suspend and
