This is still happening in 13.10, but there is a difference: before
13.10 one of the ways to get back to the right resolution was to start
'System Settings', and then start 'Displays'. That would fix the
resolution (without having to click on 'Apply').
Since 13.10 just starting 'System Settings'

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

opening System Settings - Displays caused the resolution to revert to

I worked around this by un-installing the screen saver.
Given what appears to be the 'root cause' ... my guess would be the screen
saver it provoking a 'poll'
when it locks or unlocks the screen ... Given that this will probably happen
when a KVM is switched 'away'
for long periods , it would

I removed it and restarted. Can switch through all displays and back to Ubuntu

Hi Vincent,
The link you posted worked for me. I had to back out the one made for
xscreensaver. It kept the resolution, but xscreensaver didn't turn off
the monitor (or make it sleep) it just blacked it out.
Erick,
Hope you're feeling better!

I have seen this issue on various intel integrated video chips.
The issue seemed to be caused by the KVM switch at first, but it did not return
to a proper resolution when it was removed from it.
I found a workaround here:
I did some more fiddling and I'm fairly well convinced that this is
actually a 'gnome-screensaver' bug.
I first booted into an Lubuntu Precise and installed 'gnome-desktop-
environment' which I know is Gnome version 3.0 rather than the Gnome
version 3.2 + bits of 3.4 that Ubuntu Precise uses.
This link worked for me - http://www.liberiangeek.net/2012/04/add-

If this issue is now known to be in gnome-screensaver and to be
independent of the graphics card/driver used by X, I'd think it might
help to edit the Affects stuff to reflect these facts :) I'd update
it, but I have not tested / duplicated the issue myself, and so I don't

I agree it's got to be somewhere else. It would appear that it is not
hardware specific, not video card, nor monitor, nor kvm.

Just downgrading 'gnome-screensaver' was easy but also did no good :^(

What can we do?
12.04.1 should be very stable and usable!
At least change the status!

Just noticed this AM that opening the terminal and typing xrandr also
