[Ubuntu-x-swat] [Bug 997075] Re: XOrg uses 100% CPU after upgrade to 12.04 and freezes computer
I confirm. 100% CPU by Xorg, sometimes segfaults (it restarts Xorg). I'm using binary nvidia drivers, not nouveau I did a previous-LTS to current-LTS upgrade.

[Ubuntu-x-swat] [Bug 993187] Re: ubuntu 12.04 completely freezes frequently.
I will add: not always it seems to be caused by nvidia. But always concerns irq's.
