Public bug reported:

I have a machine that shares monitor, keyboard and mouse with a second
machine via a standard KVM-Switch (USB/VGA). After updating to precise
beta yesterday, I noticed that, after having worked with the other
machine for a while and switching back to the precise machine, screen
resolution has changed to 800x600. Just opening "Monitors" from gnome-
system-settings restores the original resolution of 1280x1024, you don't
need to change anything.

This is reproducible, if you switch away from the machine long enough (I
guess until the screensaver gets invoked) resolution will be changed
when you come back. This was not the case with oneiric.

Is there some way to disable this behaviour?
