<pre>I have a Radeon R7 240 card with two HDMI outputs.
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Oland
PRO [Radeon R7 240]
When plugging a second monitor, I can't access dual monitor features. I'm using
Mate's "Monitors" GUI and only one monitor seems to be detected, even when
clicking "refresh monitors".
xrandr output:
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1920 x 1080, maximum 1920 x 1080
default connected 1920x1080+0+0 0mm x 0mm
1920x1080 0.00*
1280x1024 0.00
1024x768 0.00
800x600 0.00
640x480 0.00
The best I can get is a clone, with the display stretched on my widescreen
monitor to get a 5:4 resolution on the video-projector.
Anything I can/should do? Is this known issue?
Someone seems to have the same issue with another card:

I'm using Debian Jessie with recent kernel
4.8.0-0.bpo.2-amd64 #1 SMP Debian 4.8.11-1~bpo8+1 (2016-12-14) x86_64 GNU/Linux
and backported mesa stuff if that matters (see
