--- Comment #6 from Rafał Miłecki zajec5@gmail.com --- Created attachment 143104 --> https://bugs.freedesktop.org/attachment.cgi?id=143104&action=edit Xorg.0.log using xf86-video-modesetting
Michel has suggested trying xf86-video-modesetting. A difference from user perspective is minimal.
1) With both drivers I can use HDMI output port just fine after booting (without a docking station)
2) After that I connect docking station, connect DP, disconnect DP, disconnect docking station
3) Finally I try connecting monitor to the HDMI output again: a) With xorg-xf86-video-amdgpu I get "Output DisplayPort-0 is not disconnected but has no modes" b) With xf86-video-modesetting I get "xrandr: Configure crtc 1 failed"
