The problem may be deeper than gnome-screensaver. I experienced the same annoying symptom with a fresh install of Debian 7.0.0 on a machine behind an IOGear 8-port PS2 KVM switch. As reported above, simply opening System Settings -> Displays caused the resolution to revert to 1600x1200, as did running the xrandr command in a terminal. To determine if it was gnome-screensaver, I forced it to quit using 'gnome- screensaver-command --exit' and confirmed that the screensaver process was no longer running. However, switching to another machine for a few seconds still resulted in the display changing to 1024x768. Using Gnome Classic instead of Gnome shell didn't help. I did not remove gnome- screensaver because it required uninstalling other gnome desktop components also. My solution was to install the XFCE desktop which doesn't exhibit the resolution switching behavior -- and is more usable than Gnome3 in my opinion.

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?
