Public bug reported:

I upgraded to 12.10 successfully and didn't see any graphics problems.
Today, after my laptop was on for a while but not in a position where it
would overheat, I had random colored pixels on the screen and the mouse
position only refreshed a few times. dmesg contains "NVRM: Xid
(0000:01:00): 31, Ch 00000001, engmask 00000101, intr 10000000" but
that's all I found. Rebooting didn't fix it; I got a crash soon after
login. I went to xorg-edgers and non-compiz desktop, and now I can work
but there is still colored snow accumulating all over.
