@katastic Interestingly I've also noticed video output problems in VLC on my Lenovo Ideapad L340-17API. In my case video is present in VLC but quality is quite poor, video looks interlaced even though it is not. Workaround: reconfigure VLC to use another video output module and probably restart

I noticed that after boot with badly initialized GPU idle power consumption is 2-2.5 higher than after normal boots. But this can be fixed by putting laptop to suspend and waking it. Therefore I've extended my workaround from #3 to this: [Service] Type=oneshot ExecCondition=/bin/sh -c

This issue is not 100% reproducible. It happens after 50% of reboots and I can't figure out regularity. But I managed to contrive a workaround! ``` $ cat /etc/systemd/system/fix-graphics-after-boot.service [Unit] Description=Restart display-manager if amdgpu initialization failed
