I hacked up a very rough version of a acpivideo driver for my specific DSDT. My screen now goes off if I suspend. I also think that I figured out what I need to turn it back on on resume , however I have a problem. It seems that the 'device_resume' functions are called rather unreliably. Most of the time it is not called at all, I couldn't find a pattern yet. Is this a known problem? /* * Re-wake the system. * * XXX note that a better two-pass approach with a 'veto' pass * followed by a "real thing" pass would be better, but the * current bus interface does not provide for this. */ I found this comment, which might be related? So like I said, if I can get the resume function to work, it might be solved.
