After waking from sleep I get black screen on my notebook regardless of whether x-server was starting or no.
I am able to type commands blindly. I can also connect to system via ssh.
But after adding "nomodeset" to kernel params system suspend and resume work correctly.
I probed linux kernels 4.9 and 4.16. I also compiled modules radeon,drm,ttm from recent sources.
Situation did not change.
