Problems max. resolution mainboard with nvidia gf9300
yesterday I remotely (teamviewer) installed all available updates from the last 3-4 weeks for a ubuntu 11.10 / gnome3 box of a friend. After the update I could not get any monitor (TV) resolution hight then 1200x720. Before that it was at full HD 1920x1080. I uninstalled the restricted driver for the video card and reinstalled severeal times and also rebooted several times. No luck.
Any idea where I should have a look next?
Thanks in advance
