Comment 15 for bug 296167

I am also suffering from the same bug.

thegner@it-thegner:~$ uname -a
Linux it-thegner 2.6.27-7-generic #1 SMP Tue Nov 4 19:33:06 UTC 2008 x86_64 GNU/Linux

Ubuntu 8.10 amd64
3.0 Ghz quad core
8 Gb RAM

I am running three monitors on two nvidia cards (8800 GT / 8600 GT), with xinerama.

I found on a post somewhere to try (sorry no link handy):

Section "ServerFlags"
    Option "AutoAddDevices" "false"
EndSection

This has significantly reduced the number of times that it happens, but it still happens 1-3 times per day.

As with everyone else, the only fix is a full reboot, or an X restart (ctrl-alt-backspace).

Another oddity that I've noticed with this bug, I am still able to alt-tab between apps, and ctrl-alt-arrow, to switch workspaces, but the little notification window that pops up with those actions is seems to be 'stuck' on one monitor, where normally it is on whichever monitor the cursor is on.

As someone else mentioned above with the mouse events on the wrong monitor: I have noticed that the cursor will still change (i.e. to the text beam), but not where it's supposed to, if i have gedit running on my center monitor, the cursor will change on the right monitor in the area that would be the text area if gedit were running on the right monitor. Likewise for a nautilus window on the left monitor, the cursor will change to a text beam on the center monitor in what would be the path space of the nautilus folder. Sorry for the mouth-full on that one, I hope you followed it OK.

I have also disabled my screen saver because others out there have attributed similar problems to gnome-screensaver, but I haven't seen any difference since then.

I'm not sure what else I should provide. If I can be of any help with information of symptoms, let me know.
