Bug Description

This problem happens when I close the laptop lid (in Lucid) and then open it: the screen remains completely black until I repetely hit CTRL-ALT-F1 CTRL-ALT-F7 ...
Then the screen is restored and works well.
This is in my .xsession-errors

Thanks Leann.
I have to add that this problem is also valid when resuming from
suspend, but the result is worse: I cannot recover the PC in any way.

The issue persists.

Note that this bug does not affect gnome-power-manager normal screen
blanking after a period of inactivity. It is only valid when closing
the laptop lid.

@Nicolo -- is your machine set to suspend when the lid is closed? I am hearing similar reports of no screen on resume from suspend. Have you tested suspend?

Nicolò Chieffo (yelo3) wrote :

My machine does not suspend with lid close.
If I set up my machine to suspend with lid close the brightness error
is unrecoverable and I have to power cycle it.

Nicolò Chieffo (yelo3) wrote :

Is there anything else I can do for you?
I'm afraid that since this error is present in the final 2.6.32
kernel, I will have to cope with it in ubuntu 10.04 :(

Working with upstream I figured out that passing "nomodeset" to boot

This should be interesting: http://bugzilla.kernel.org/show_bug.cgi?id=14997

"I took a bit more at this problem, too, for the same machine Matthias is
checking (945GM). The problem looks like that the encoder->crtc is cleared at
lid close, but it's never recovered properly.

Namely, drm_crtc_helper_set_config() is called by intel's set_config, and this
calls drm_helper_disable_unused_functions() that prunes off crtcs used for
LVDs. Then, at lid open, drm_helper_resume_force_mode() is called, but this
resumes the CRTCs that are already enabled, thus it doesn't help for resuming
LVDS."

There is also a patch attached which, according to Takashi Iwai, fixes the problem. I don't know whether this is also the case for the GM45.

I'm CC'd on the upstream kernel bug Kai mentioned. If anything comes of it, I'll build a test kernel to see if it fixes the issue here.

The change has been sent upstream to the -stable queue, and if accepted it will automatically get pulled into Lucid.

Unfortunately when I open the lid I still see the display notification:
"could not switch the monitor configuration / could not set the
configuration for CRTC 64"
and it feels that the PC is unresponsive for 4-5 seconds (slow keyboard input)

this is the output of dmesg:

Can you please tell me which upstream patch you have applied? So I can

Chase Douglas (chasedouglas) wrote :

@Nicolò Chieffo:

I applied this patch: http://lists.freedesktop.org/archives/intel-gfx/2010-February/005902.html. It has not hit the intel-gfx git repo, so it still has a ways to go before it's incorporated to a point where it will be in the lucid kernel. If we get closer to the lucid release and it still isn't upstream we can take another look at including it in lucid ourselves.

Nicolò Chieffo (yelo3) wrote :

Hi back, recently my kernel got upgraded so I lost the patch and when
I open the lid I have to do the VT switch trick.

But now I noticed that it does not always work, because sometimes when
I switch to the VT, Xorg crashes and I obtain a .crash report.
Should I attach it here, file a new bug, or wait for the patch to land
to the new kernel and see if this still happens?

Chase Douglas (chasedouglas) wrote :

@Nicolò Chieffo:

FYI, the patch is taking a longer to get upstream than would be desired as there's some question as to whether it is the best fix for this issue.

I would assume at this point that X crashing is another symptom of this bug. If X still crashes when a patch fix is in the kernel, then it would be a new issue and would require a new bug.

Nicolò Chieffo (yelo3) wrote :

Ok, I will wait for a fix, then test again the Xorg problem.
In the mean time is there any possibility to disable screen blaking on
lid close?

Thanks!

Chase Douglas (chasedouglas) wrote :

I'm unaware of any way to force such behavior.

Chase Douglas (chasedouglas) wrote :

Although the fix hasn't reached upstream, I believe upstream is working on solving the solution through further development work to make things behave more "correctly". In the meantime, we need a fix for Lucid, so the patch was committed to the lucid kernel tree. Please test the next lucid kernel release (should be sometime in the next few days) to ensure it resolves this issue.

I am still encountering this problem with kernel 2.6.32-16.25. The kernel from Chase Douglas fixes the issue, the current kernel in lucid does not.

In my case X crashes when opening the lid, so I don't know

Chase Douglas (chasedouglas) wrote :

@Kai Jauch:

The 2.6.32-16 kernel has the 2.6.33 drm (graphics drivers) stack in it. This was done for many varied reasons, one of which is better support for intel graphics. If you are having issues now, I suggest opening a new bug just to keep things separate and not get too tangled up with the fix for the old graphics drivers.

@Nicolò Chieffo:

You can test this by switching to another VT, closing the lid, and opening it back up. I think this should exercise the same bits as doing it in X. If X still crashes and screws things up you can stop it temporarily: "sudo stop gdm"
