The machine isn't completely frozen after all. It replies to ping and ssh asks for password. But after inputting the pw, the connection freezes. IO-problems?

Another reboot without changing anything, and works fine for now. Logs show the last Xorg session ending into "(WW) Jul 26 13:54:34 NVIDIA(1): WAIT (0, 6, 0x8000, 0x0000f50c, 0x0000f50c)".

Seems very, very random indeed...

Re: 2nd screen starts to flicker during gpu acceleration
 
Today I noticed that trying to go from X to console after the 2nd screen has stopped working will result in X freezing and taking 100% of one CPU core. Nothing changes in logs when this happens.

Trying to restart gdm at this point gave a bunch of identical stack traces (log attached). Simply trying to stop gdm froze the X and the stopping command.

Re: 2nd screen starts to flicker during gpu acceleration
 
I hate to tell you this, but 100% of the time I have had these type of errors it was fixed by replacing some piece of hardware, the video card, memory, motherboard and once even the processor. I can't say that there was not a software error, but it was either not compatible with the hardware installed, or the hardware was actually bad. I think in every case it was the latter, no matter how much I would have liked it to be otherwise.

Yes, this looks a lot like bad hardware.

Anything like this: http://www.playtool.com/pages/artifacts/artifacts.html ?
