I'm using the binary AMD driver as opposed to the open source ones (for performance reasons). I'm using a monitor-less server with a remote desktop client (nomachine). One of the issues I am having is that with the binary AMD driver I can no longer 'force' my desktop resolution to 1920x1080, it maxes out at 1600x1200 and it's unable to be changed:

   gary@exar-kun:/etc/X11$ xrandr                                                                   
   Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192

   1600x900       60.0

    v: height 1080 start 1083 end 1088 total 1120           clock   60.0Hz

I can't use xrandr to set the physical resolution without a monitor attached and the catalyst control panel shows 2 resolutions that have super high settings (4000x4000 and 2500x1600 (or so))

Is it possible to use the CRT2 in headless mode instead of 'stretching' the framebuffer? I can do this without using any crazy xorg things, ie:

xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
xrandr --addmode VGA-0 "1920x1080_60.00"
xrandr --output VGA-0 --mode 1920x1080_60.00
