I just upgraded to Ubuntu 11.10 Oneiric Ocelot. Everything works fine except for the screen resolution for my monitor which is wrong. In the system settings I can change it but the one that goes with my monitor is not listed.

In system info, the graphics driver is unknown. My graphics card is:

sudo lshw -C video
