Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I've just upgraded Ubuntu system from 11.10 to 12.04. In 11.10 graphics were okay. I was running unity 3D and now after upgrade I just got unity 2D and max resolution 1024x768.

How can I fix this?

We need more informations. Can you send us the exact model of your Intel graphic card ('lshw -c display' can give it if you don't know), do you have any .xsession-errors file in your $HONE directory, could you send the output of /var/log/Xorg.0.log? –  Huygens Apr 27 '12 at 12:53

I had the same problem after the update. You should install glxinfo:

sudo apt-get install mesa-utils
