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.
