when i run boxee full screen, it takes up most of my right monitor, some of my left one, and pushes my left display over a bit, i haven't managed to take a proper screenshot of it though. they make the problem look better than it actually is.

runs fine in windowed mode, compiz is OFF.

if anyone needs anymore info, contact me.

can you please try with a plain xorg.conf with only the nvidia driver, and without the nvidia specific options?

is there a reason for having two same monitor type, yet one using DPMS and the other with preset sync values?
