after closing the lid and reopening it the screen remains blank

after closing the lid and reopening it the screen remains blank

[Norbert Preining]

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.

FWIW, 2.6.36-rc3-00396-gbe6200a suspend-to-ram works for me on GM45
(Dell E4300).  I am running Ubuntu with xorg-edgers from a few months
ago:

xserver-xorg-core 2:1.6.5+git20091107+server-1.6-branch.2dbcb06a-0ubuntu0sarvatt~karmic
xserver-xorg-video-intel 2:2.11.0+git20100415.c374c94e-0ubuntu0sarvatt~karmic

There are several regression fixes pulled after 2.6.36-rc3 in merge
commit 4eab8a5717f5, can you try current linux-2.6.git ?

If it still fails, please post
 - lspci -vvv
 - /var/log/Xorg.0.log from after the failure
 - dmesg

I never said that it has anything to do with suspend to ram.

In fact, suspend to ram works perfectly without any problems. I only
reboot after I installed a new kernel ...

I will try some older kernels and see if it is a kernel or userspace
issue.

Ah, sorry for misunderstanding.  My GM45 system is configured to
automatically S2R on lid close so I tend to conflate the two...

Do try the current tip and/or describe which post-rc3 kernel fails for
you, just to verify.  Also, is there anything in Xorg.0.log from when it
fails to restore the video?

Thanks for reporting the regression, it'll be good to get it fixed ASAP.

over here:
cat /etc/acpi/sleep.sh

if grep -q close /proc/acpi/button/lid/LID0/state
then
/usr/sbin/s2ram
fi

works reliably over here(knock on wood..)with radeon not sure
with intel cards..

Mine, too, but not when running on AC.

> Do try the current tip and/or describe which post-rc3 kernel fails for

current tip works fine. It seems that I was hit by one of the fixes
I found in the git log fixed after the build I did 
(drm/i915: Prevent double dpms on, or drm/i915: Clear the vblank status 
bit before polling for the next vblank)

> Thanks for reporting the regression, it'll be good to get it fixed ASAP.

Seems to be already fixed. Sorry for not testing the tip first.

Best wishes
