Matthias, All, I pulled the latest updates from the git repository tonight to test whether it would now work with my laptop again. No joy :-( Same issue. The display acts like it is completely unpowered after kdm start. I have collected a new log file for your review (attached). Hopefully it will provide some insight. Let me know if you have any ideas. Thanks. -- David C. Rankin, J.D.,P.E.
