I'm using Ubuntu 12.04 x64, nVidia graphics with the "current" driver. Same happened with the "current-updates" driver.

Every now and then, while watching flash playback (not every time) Ubuntu crashes to login screen.

dmesg:

Xorg[8478] general protection ip:7f5f27e466a9 sp:7fffdda31ff0 error:0 in nvidia_drv.so[7f5f27de5000+6e0000]

/var/syslog:

The "Zasoby chwilowo niedostępne" line means "resources temporarily unavailable".

I'm using Firefox 12.0.

It's this bug:

Please log into Launchpad and mark the bug as affecting you too.

What browser are you using? I have seen this happen in Chrome (it uses hardware acceleration) if it doesn't like the graphics card, but not in Firefox. If you run

sudo apt-get update
sudo apt-get upgrade

do you have packages that are held back? If so run

sudo apt-get dist-upgrade

I had issues before with an Intel card that would randomly crash back to the login screen, and it was because I hadn't updated my Linux headers.

Everything is up to date. I'm using Firefox. –  Piotr May 12 '12 at 6:39
