Title:
Radeon driver only provides 1024x768 resolution
Status in linux package in Ubuntu:
Confirmed
Status in xserver-xorg-video-ati package in Ubuntu:
Confirmed
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)
