Title:
  Radeon driver only provides 1024x768 resolution

Status in linux package in Ubuntu:
  Confirmed
Status in xserver-xorg-video-ati package in Ubuntu:
  New

Bug description:
  I'm using the latest development version of xenial. My graphics card
  is AMD HD7950 and I use an mini-DP to DP converter to connect it to an
  Acer XB240H monitor. The system works well in Windows 7.

  While using the open source radeon driver, the system was only able to
  detect resolution up to 1024x768:

  $ xrandr
  Screen 0: minimum 320 x 200, current 1024 x 768, maximum 16384 x 16384
  DisplayPort-0 disconnected (normal left inverted right x axis y axis)
  DisplayPort-1 connected primary 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
     1024x768      60.00* 
     800x600       60.32    56.25  
     848x480       60.00  
     640x480       59.94  
  HDMI-0 disconnected (normal left inverted right x axis y axis)
  DVI-0 disconnected (normal left inverted right x axis y axis)
