It looks like the problem with 295.40 version of Nvidia driver is confirmed even by Nvidia: http://www.phoronix.com/scan.php?page=news_item&px=MTA4ODc I've switched back to 295.33 version, using this PPA: https://launchpad.net/~ubuntu-x-swat/+archive/x-updates and it looks stable right now. I know that I'm now vulnerable to a security problem, but since it's not a remote security problem and I'm the only user of this PC it's pretty fine for me.
