Public bug reported: I had installed the package nvidia-331 and after some updates (may have included a kernel update but i'm unsure) the graphical interface wouldn't start. I got automatically pushed to tty1 and logged in there. I tried sudo apt-cache search nvidia and saw that there was both nvidia-331 and nvidia-331-updates, so i continues with sudo apt-get nvidia-331-updates. That's when this bug happened i think. Just afterwards i hit again a sudo apt-get install nvidia-331-updates and it worked. I'm now, after a reboot, logged in the graphical interface on tty7 as "usual".
I hope this helps.
