Hi, since early 2.6.37 (I haven't bisected when exactly) my screen doesn't get on after it got into standby mode. I have to either change to a text console and back (if it gets to standby by the screen saver) or close the lid on my laptop if I try: xset dpms force standby
Changing to a text cosole doesn't help in dpms case.
When I boot back to 2.6.36-00022-g2b666ca this works fine. Is this a known issue?

Nothing appears in the log during dpms standby and the lid close. dmesg output is attached. Config is attached as well.
Let me know if you need further information.
Thanks
