(In reply to taijian from comment #29) > 3) There is a new bug, probably introduced by this commit: > https://cgit.freedesktop.org/~agd5f/linux/patch/ > ?id=7c8c32854566dd9fb2ad4108029670604bc77b19. On hybrid gpu laptops amdgpu > does not actually control the brightness of the internal screen, because > that is controlled by the iGPU. So amdgpu should probably not try. Maybe put > a check in there? There is a crash referenced related to this issue in the > attached dmesg output, look starting at [10.234751]. > The patch you're referencing only applies to legacy display code (dc=0). The stacktrace you show is with DC display code (dc=1). This probably happens because we advertise a backlight device if we have an eDP connector available, even if it's disconnected. See https://cgit.freedesktop.org/~agd5f/linux/tree/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c?h=drm-next-4.17-wip#n3601 for more info. Unfortunately I can't comment on the atpx stuff. Harry
