Bug Description

Machine details:
Lenovo Thinkpad T400
Intel® CoreTM2 Duo processor P8400
Integrated Intel® GMA 4500M HD
Ubuntu 2.6.38-8-generic-pae (32bit)
uname -m i686

Symptoms when the problem occurs:
Display stops responding. There are 3 types of failures noticed:
- Display may randomly flicker (not garbage but toggles between desktop and couple open windows)
- Mouse moves but everything else is forzen (including computer time)
- Display is frozen, includes mouse pointer not moving
When the display is frozen, we are able to ssh into the machine. Further we are able to play music etc using the hot keys.

Problem has occured:
Can not correlate to any particular program or task. Seems to be random in nature.
- Has happened when actively using the laptop on AC power without the laptop ever going to sleep or screen saver mode after power up (happened within 10 minutes of powerup). Google Chrome was open along with Clementine music player at the time of failure.
- Has happened after 4 days of actively using laptop (during the 4 days laptop was put to sleep and woken up multiple times

Saw this with sympthom no. 1 after installing the latest kernel from Natty-porposed. Previously I suffered from https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/761065

Changed in xserver-xorg-video-intel (Ubuntu):

Does anyone know if this still occurs in 11.10?

Hey nodeax,

You filed this bug report against natty, but I see it's still open and
doesn't appear to have much activity recently. So, now that oneiric
is released and stable, this may be a good point for you to upgrade
and re-test if this issue is still present there.

If it's solved in the new release and you think it's worth backporting
the fix, please indicate that. Or if having the fix in the new release
is good enough, feel free to close out the bug (or let us know and we'll
close it.)

If it's not solved, leave the bug report open. I can't promise we'll
get to it (we get way more bugs filed than we can usually get to), but
your testing and feedback can help out if and when we do.

I'm having the same problem on oneiric. The screen randomly freezes for a few seconds (the mouse still moves, but everything else is dead), then everything turns black for a second, and then it all goes back to normal. Afterwards, I find this in my syslog:

[ 200.319085] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung

The "enabling SSC on PCH"-error also appears randomly from time to time, but I don't notice it otherwise.

Also, it only seems to occur when I have my second screen connected.

This might be solved in Mesa 7.11.1.

After I have installed Intel drivers from this ppa:glasen/intel-driver (https://launchpad.net/~glasen/+archive/intel-driver) I can not trigger this bug anymore. Before it always happened after a few minutes running a webgl demo in chromium browser. E.g. http://dl-developer.sonyericsson.com/demo/webgl/blog/webgl_materials_normalmap.html or http://www.ambiera.com/coppercube/demo.php?demo=dynamiclight&mode=webgl

Having similar issues in 12.10. Everything is frozen for a few seconds and after that Ubuntu wants to send a bug report. dmesg shows hangcheck timer for i915 elapsed.

Yes, I started getting this too after a recent update. Very annoying. I wasn't sure which package update caused the problem but I rebooted into grub and selected the previous kernel (3.2.0-38) and it seems fine so far. Something in that update has reintroduced the problem. Can we re-open this or is there already a new bug?
