I see these messages in my journal: Jan 17 15:33:08 orionis kernel: [drm:radeon_dp_link_train] *ERROR* displayport link status failed Jan 17 15:33:08 orionis kernel: [drm:radeon_dp_link_train] *ERROR* clock recovery failed However that led me to the other option I set for the radeon driver: DRI3. I switched to DRI2 and this issue is gone. I did see a black screen when trying, but that was the other Plasma bug. Windows etc. show up on the screen and can be used. I'll report a bug upstream. -- You are receiving this mail because: You are watching all bug changes.
