Comment 41 for bug 760632

@Stefanek kudos for a stable work-around! I only replace Xorg with the 1.9 version and left the nvidia driver at 270.41.06 and after dragging Konsole across 2 monitors for 5 minutes I still didn't lock up!

And I agree with the general consensus that this is quite severe and taking way too long to fix. I just disabled the update notifications for Kubuntu and I'll resume updating my system once this bug is resolved...
