--- Comment #22 from Shih-Yuan Lee fourdollars@gmail.com --- (In reply to Mike Lothian from comment #19)
You have to blacklist radeon to use amdgpu as both modules try and claim the device
After I blacklist radeon, there is no AMD graphics provider from `xrandr --listproviders`.
[ 1.937326] amdgpu 0000:01:00.0: enabling device (0000 -> 0003) [ 1.937633] amdgpu 0000:01:00.0: SI support provided by radeon. [ 1.937635] amdgpu 0000:01:00.0: Use radeon.si_support=0 amdgpu.si_support=1 to override.
After I use 'radeon.si_support=0 amdgpu.si_support=1', X window system can not start up.
