Comment 127 for bug 973096

Hi there,

Possible fix? At leasts works well for about 2 hours now:

» Kubuntu PRECISE (12.04) 64
» Intel I7
» 6 gb Ram
» GTX 560 Ti2 x2 in SLI
» xinerama (3 24" monitors)

Installed newest NVIDIA proprietary driver (NVIDIA-Linux-x86_64-295.59.run) + reboot

kdm restarted then X crashed:

Then I apt-get update & apt-get upgrade, with this newest packages, since my station was shutdown since 2 weeks now, waiting for a possible fix.

Restarted kdm, loggued, working now for 2 hours

I encourage others here to download LATEST nvidia proprietary driver, upgrade every possible package (see there is xorg stuff, flash & others here...), and report if this fixes something for you or not.

Hope this helps !
