I merged 1037895 into this Changing from the intel xserver to gnome-screensaver; from the reports it doesn't seem to be Intel specific. Whether it's actually gnome-screensaver or something else seems to be difficult to tell; most people seem to be saying removing it helps them, but #30 is not sure; but the conclusion seems to be other desktops don't suffer from it.
However, the fact that xrandr reprobe causes it to sort out seems to suggest it might not be the screensavers problem? ** Package changed: xserver-xorg-video-intel (Ubuntu) => gnome-screensaver (Ubuntu) ** Changed in: gnome-screensaver (Ubuntu) Importance: Undecided => Medium ** Tags added: release-regression ** Tags removed: release-regression ** Tags added: regression-release -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/988290 Title: Resolution change with KVM switch on Precise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/988290/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
