Well if pm-suspend works but lid closing is not reliable I think the most likely explanation ist that the lid events gets lost somewhere. Is there anything in dmesg after a failed suspend attempt? The flickering when re-opening the lid is annoying but somewhat expected - we switch off the panel uncoditionally when closing the lid. > > I receive the following warning in dmesg (after both successful and > > unsuccessful suspends): This one is pretty interesting - obviously we still have issues with the panel unlocking. Can you please boot with drm.debug=0xe and attach the full dmesg after one suspend/resume cycle?
