I am seeing same problem here on self-built (2+ years ago) amd64 machine. Have been running fine using wheezy with nvidia driver for ages, latest upgrade to 295.20-1 causing these random X server crashes and hence logouts, essentially rendering the machine unusable in graphical mode.
>From Googling around it seems the problem is pretty widespread -- it's being reported in Archlinux, Debian and Ubuntu forums (fora?) Suggests the problem is upstream? Don't know. Anyway, the pretty-much-universally recommended solution is to downgrade to 290.10 -- which I would do except that I don't have the packages anymore as I did an aptitude autoclean after the last upgrade... Where can I get my hands on the old packages now? They don't seem to be in the debian package pool any more...
