Fixing screen taring on Xorg HiDPI. [FIXED]

roshhh · 2017-03-13 22:27:52

Since wayland does not support non integer scaling or the the fractional xrandr zooming out trick, I am trying to get the desktop working on Xorg.

However on Xorg I get horrible screen taring. I am using an RX480 GPU with amdgpu driver. Whenever I add a configuration file to the /etc/X11/Xorg.conf.d/ named 20-amdgpu.conf I can't get past the logon screen.

Section "Device"
     Identifier "AMD"
     Driver "amdgpu"
     Option "AccelMethod" "glamor"
     Option "DRI" "3"
     Option "TearFree" "on"
EndSection

I have tried the above config without the options but It still does not boot, I only get to the desktop if there is no configuration file.

Anyone got any ideas?
