I've installed Debian testing from
netist image in a AMD Radeon system. I am using
Xorg and awesome wm. The default screen resolution is 1024x768 while my screen supports 1366 x 768.
fglrx but they failed.
A proprietary ATI drivers however solved this problem, but gives a slow scroll effect.
I've also used crunchbang Linux and it displays the corect resolution without a
xorg.conf or ATI drivers.
