Xorg.0.log
Running Ubuntu Wily x64 on a Radeon R9 280.
when i rotate the screen on one of my monitors the screen corrupts though the
mouse cursor i can still move about as normal.
rotate was working previously on Ubuntu Vivid.
tried the latest git from xf86-video-ati and it's still broken.
xrandr output:
