(In reply to Takashi Iwai from comment #15) > Hm there is no added debug message. Could you rebuild initrd (e.g. run > mkinitrd) and retest? mkinitrd did the trick but now sddm does not start automatically for some reason so I have to do startx from tty but I can rollback. The updated log is in the same location -> https://github.com/antony-jr/lenovo-legion5-15arh05-scripts/blob/main/AMDGPUDebug/dmesg.txt For more debug info I tried to decrease the brightness to 0% and go to 100% again, hope that helps.
