Description Dmitry 2018-12-11 16:56:32 UTC 
Black screen via DP when using XF86-video-ati driver. Through VGA there is no problem.

DRM driver: amdgpu
GPU: AMD Kaveri R7 (A10 7850K)
Distr: Arch
Options root= amdgpu.cik_support=1 radeon.cik_support=0
Comment 1 Michel Dänzer 2018-12-11 17:00:14 UTC 
xf86-video-ati can't work with the amdgpu kernel driver. If you force it via xorg.conf Driver "radeon", that's a configuration error.

If that wasn't the problem, feel free to reopen and attach the output of dmesg and the Xorg log and xorg.conf files.
Comment 2 Dmitry 2018-12-11 17:04:17 UTC 
Understood. Just with xf86-video-amdgpu also have problems, then create a report on the xf86-video-amdgpu driver.
