They don't do anything. > amdgpu.dc=1 amdgpu.modeset=1 Same here with the kernel arguments, amdgpu.modeset doesn't exist afaik. amdgpu.dc=1 is the default (and only allowed configuration) for your hardware. For the actual issue, the "removing output ..." line is probably just from KWin quitting, there's no "New output on GPU ..." afterwards for adding the output again. Is your SDDM running in Xorg, or kwin_wayland? Switching from Xorg or another compositor to KWin (and vice versa) will change the bit depth and may require a modeset, which is the blanking you see. It shouldn't take that long on a laptop display, but that's all on the driver side and not something we can influence. Also, please attach the output of > kscreen-doctor -o in the session. -- You are receiving this mail because: You are watching all bug changes.
