That is very cool. How did you figure out what to do? I am currently using the nvidia proprietary drivers
on my system with a 6600GT nvidia dual head dvi video card
1920x1200 on left and 1280x1024 on the right
and i have been using the nvidia setup which leaves me with
a total desktop of 3200x1200
where I can't see the bottom of the right screen because it thinks it is 1200 high whereas it is only 1024 so it is off the screen.
I wonder if the xrandr line can fix it?
would it work with my xorg?
what would i use?
