Public bug reported:
Binary package hint: xserver-xorg-driver-all
The system is a Dell PowerEdge 400SC. It has been running properly with
a 14" generic CRT monitor. A few days ago, I plugged in a Samsung
SyncMaster 570S TFT 15" flat screen monitor, which initially worked well
without a change in xorg.conf, at a 1024x768 screen resolution (which is
the maximum that the Samsung monitor will handle).
I just tried to install some new cursor packages. After that, and a
restart of X, the system reconfigured xorg.conf, failing to detect the
display hardware properly, and ended up with a default xorg.conf, which
only allows me to run at 600x800. Also trying to reconfigure the screen
with dpkg-reconfigure xserver-xorg produced the same result (whether or
not I selected using a frame buffer).

I tried booting a Knoppix live CD, and Knoppix was able to use the
proper screen resolution of 1024x768 automatically.
This is similar to bug #217004, to which I appended my problems with a
gBox computer, which is connected to the same monitor, shared with a KVM
switch.
