I had problems with my old jaunty installation so I decided to give Karmic a try.
I installed full ubuntu Karmic with Nvidia 190.53 drivers and XBMC 9.11 RC1.
My system is Pundit P4N9300 with E5200 procesor, 4GB ram and 1.5 TB hard disk.
I managed to get everthing working but I still have trouble with changing the screen resolution in XBMC to 1920x1080@24hz.
I have no problem with setting this resolution in gnome but when I start XBMC the resolution defaults to 1920x1080@50hz

When I check summary info my screen resolution is 1920X1080 @ 50.00 HZ (67-84 HZ) this last figure fluctuates constantly.

I tryed editing xorg.conf using couple of tutorials on this forum but the result was that I could not boot into anything so went back to the original xorg.conf.
Any help would be appreciated
