I've recently upgraded my ubuntu to 14.10 and problem also occurred. I've removed bumblebee and primus (just remove not purge) and it didn't help. Downgrading ubuntu-drivers-common to 0.2.91.4 also failed.
But I've found out that my X.org is complaining about missing nvidia module, and indeed there was no such file in /usr/lib/xorg/modules/drivers. Re-installing nvidia-331 did not helped. So I simply copied nvidia_drv.so to drivers and libglx* to /usr/lib and it now works! Although it lacks hardware acceleration but I'm able to finish my work for now. Maybe somebody will guide me - which package is responsible for linking appropriate nvidia_drv.so to X.org modules? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1374871 Title: upgrade from 0.2.91.6 to 0.2.91.7 breaks my X.org (nvidia) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1374871/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
