Comment 1 for bug 711122

I'm also using a 1101HA, and just installed the EMGD drivers from the EMGD ppa. I have full 1366x768 support:
xrandr --prop
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1366 x 768, maximum 1366 x 768
default connected 1366x768+0+0 0mm x 0mm
   1366x768 60.0*
   1280x768 60.0
   1280x720 60.0
   1024x768 60.0
   960x540 60.0
   800x600 60.0
   800x480 60.0
   720x576 50.0
   720x480 60.0
   640x480 60.0

How did you install the drivers? Can you add your xorg log?
