Default Lenovo T520i X11 Intel i810 "static display" issue

I've been running into an issue with a Lenovo Thinkpad T520i running
squeeze where the X11 display goes into a sort of "static" state. It's
usually after a pm-suspend or pm-hibernate (but not after all
suspend/hibernates), and sometimes simply when awakening the
screensaver. Restarting X generally (always?) clears the issue, but
doesn't do much for preserving session state.

The symptoms are that the display doesn't update -- while it's viewable.
There's no visible response to keyboard or mouse inputs. The pointer
itself /does/ move around the display, but windows don't take focus,
won't resize or move, etc.

However if I toggle away (<shift><alt><F1-6>) then back to (<alt><F7> or
<alt><F8>) the display -- the changes /are/ reflected. I've taken
advantage of this to shut down windows/apps cleanly.

If i restart X ("sudo /etc/init.d/kdm stop; sudo /etc/init.d/kdm start"
from another virtual console), X works properly, usually.

I've noticed this under several desktops / window managers (GNOME, KDE,
XFCE, twm, wmaker). It doesn't appear to be specific to the window
manager.

Restarting the window manager doesn't clear the behavior.

Occasionally when xscreensaver is activated, moving the mouse won't
bring up the password dialog, but the mouse is limited to moving within
the bounds of where that dialog would be.

Graphics devicde appears to be Intel Integrated Graphics Chipsets: i810
famiily.

I don't find any apparent error output in the usual places
(/var/log/messages, /var/log/

I'm noticing a reference in the pm-utils runfiles to a video
suspend/restore script:

/usr/lib/pm-utils/sleep.d/99video hibernate hibernate:success.

... and that there are some quirk modes supported, though I don't see
one for intel, and I'm not using any quirks that I'm aware.

1: Any idea what the bug is? Or a fix?
2: What package(s) should I file it against?

What additional information would be helpful?

Any way I can trigger / gather more debug info? Including, say, some
CLI X diagnostics run from a console with appropriate $DISPLAY values
set.


Thanks in advance.

It appears to be a bug in xserver-xorg-video-intel that occurs
under kernels 2.6.38 and 2.6.39. The latter seems to help some --
in my case anyway -- but the problem is still there. See bug
622308 (which has been closed); bugs 626337 and 627249 are similar.

(I'm running an Asus laptop with an Intel 965GM chipset.)

Thanks, Bill.

Any chance that the video codec and GLX issues I'm having are also
related?

I can play Flash videos but not full-screen. Attempting to use any
video codec I've tried so far in mplayer/xine hangs the video session
entirely.

... and: I'm running 2.6.38-2-amd64

Will try the .39 upgrade.

I don't see those problems. Full-screen video works fine for me in
both Opera/Flash and xine.

I'm seeing the same issue with a 2.6.39 kernel. I'll try a 3.0 rc as
well, but so far no joy.

I strongly recommend 3.0 kernel for Intel Sandybridge for various reasons
including a strange lockup bug that was discussed on linux thinkpad
mailing list apparently has been fixed since then.

And then the new Sandybridge Acceleration Architecture which easily
doubles FreeDroid RPG framerate with Full HD display from 30 to 60 fps is
only in 3.0.

Default Lenovo T520i X11 Intel i810 "static display" issue

In response to a previous thread:

Dr. Mobius, Bill Brelsford, et all:

Did anyone find a solution or even a cause for this "static display"
problem upon resume from suspend?

I see that Martin Steigerwald claims that upgrading to 3.0 solves the
problem, but it hasn't solved the problem for me- I am running 3.1.0-rc1
with all upgraded packages on my Thinkpad T520 and the problem persists.
In looking around on the Internet I see that others have the same problem,
and _sometimes_ upgrading mysteriously helps, but no one seems to know a
definitive answer.

I would appreciate any help anyone can offer.

The symptoms are that the display doesn't update -- while it's
viewable. There's no visible response to keyboard or mouse inputs.
The pointer itself /does/ move around the display, but windows
don't take focus, won't resize or move, etc.

However if I toggle away (<shift><alt><F1-6>) then back to
(<alt><F7> or<alt><F8>) the display -- the changes /are/
reflected. I've taken advantage of this to shut down windows/apps
cleanly.

If i restart X ("sudo /etc/init.d/kdm stop; sudo /etc/init.d/kdm
start" from another virtual console), X works properly, usually.

I've noticed this under several desktops / window managers (GNOME,
KDE, XFCE, twm, wmaker). It doesn't appear to be specific to the
window manager.

Restarting the window manager doesn't clear the behavior.

Wow! I wish I knew of a way to help. I just got a T520i (Core i3
processor). I installed testing on it with linux-image-2.6.39-2-amd64.
That has since been upgraded to 3.0.0+39 with the old image being
removed. The first kernel worked perfectly for me. Only display issues
on this are the ones common to all of my testing systems -- GTK and QT
apps run via SSH -X session on remote systems show some minor but
annoying corruptions. But I haven't seen any GUI responsiveness issues
(on local or remote apps) like the ones you mention.


I have to wonder if this is a driver issue for a specific video
subsystem that you folks are seeing.

Please try exactly 3.0.0 from the debian package. This is what I am using
with Debian Sid.

Might well be that 3.1.0-rc1 has some bug. Its a rc1.

I am using KDE 4.6.5 with Powerdevil via pm-utils hibernation or suspend
to ram and both work out of the box.
