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

if you change up kernels and one of them causes this..then I would do a bisect.. but if changing kernels makes no diff, then it's userpsace related(but could be wrong) i.e. on my machine I use acpid /etc/acpi/lid.sh in there its a simple call to s2ram (works fine(with radeon though))looking at some of the distros scripts(no-offense) theres loads of stuff in there todo all kinds of calls..

hope this helps.
