This question already has an answer here:

I came back from vacations and installed the updates available for Ubuntu 12.10 as I always do. The system asked me to reboot and when I did it started again but in the screen some artifacts appeared (which may mean it's a vga driver problem). When the desktop showed up, the resolution was smaller and the Unity launcher and the systray had disapeared. All I could do was to open the terminal with Alt+Ctrl+T. The buttons to close and minimize in the terminal windows had disapeared as well.

To fix the problem I reinstalled Ubuntu 12.10 by formatting the PC but when I installed the updates again the same thing happened which means that I can't do it again because the result will be the same.

Anyone knows what to do?

Thanks!

  • Please identify what video card you have. This is almost certainly a bug report. – Panther Feb 15 '13 at 20:02
  • I can just speculate without you posting actual error logs. Lately there have been many problems like this with nvidia drivers. If so sudo apt-get install synaptic, sudo synaptic and in the software sources select test the nvidia graphics driver. – con-f-use Feb 15 '13 at 22:07
  • @bodhi.zazen My video card is a Zotac GeForce GTX 550Ti. I installed the drivers using this method – Pablo Viollier Feb 16 '13 at 14:20
