Subject: after closing the lid and reopening it the screen remains blank

Hi all,

running: 2.6.36-rc3+ (from git) on Integrated Graphics Chipset: Intel(R) GM45
(Sony Vaio Z11)
Debian/unstable, so xserver 1.7.7, intel driver: 2.12.0

since some recent kernel I have the following problem: When closing the
lid on power, so the machine does not suspend, the backlight is properly
turned off.

But when I open the lid again the backlight goes on, but there is nothing
to see: No screensaver, no activity, nothing. Switching to Console in
blind didn't work either.

The machine is still responsible (Sysrq, but also CapsLock), and 
killing the X process with Ctrl-Alt-Backspace gets me back a working
X.

I am quite sure that it *was* working in former time, but cannot
pinpoint eaxactely when the problems started.

If you need any further information or testing, please let me know.
But it will take some time until I am back somewhere where I can
ssh into my machine (or try if I can ssh into).

Best wishes

Norbert
