--- Comment #15 from Wolfgang Wander
OK, then could you fiddle with i915.enable_dpcd_backlight=xxx boot option? Pass 0, 1, 2 or 3 to xxx.
0: no change 1: no change 2: no change 3: no change in all cases the backlight comes on, but the screen itself stays black. Do you want dmesgs of these attempts, with drm.debug=0x1e? And if so, with the SuSE kernel or the vanilla 5.12.0? Wolfgang -- You are receiving this mail because: You are on the CC list for the bug.
