Description keesdejong 2012-05-31 04:31:46 UTC

Quite a few people are complaining about freezing laptops. The screen freezes but the mouse is still movable. In the logs at /var/log/Xorg.0.log the following pops out: http://paste.debian.net/172156/

The only way to manage to reach the system is trough a SSH connection. Switching to other TTY's is not possible. These crashes occur when copy pasting data, e.g. in LibreOffice Calc or in Thunderbird. The logs point towards Xorg which is run by the Intel driver.

Here is the information about my CPU: http://paste.debian.net/172161/
I and other people use the Lenovo X220 with Ubuntu 11.04 installed.

These Intel packages are installed:
$ dpkg -l | grep intel
ii  intel-gpu-tools                       1.0.2+git20100324-0ubuntu1                 tools for debugging the Intel graphics driver
ii  libdrm-intel1                         2.4.23-1ubuntu6                            Userspace interface to intel-specific kernel DRM services -- runtime
ii  xserver-xorg-video-intel              2:2.14.0-4ubuntu7.3                        X.Org X server -- Intel i8xx, i9xx display driver


I would love to see a fix for this because it really makes people unhappy.

Your drivers have numerous known hangs. You need to upgrade both the kernel and ddx for critical stability fixes.

Which kernel version do you mean? I run 3.2.18, others run 3.2.0. What do you exactly mean with DDX? And which version should that be? And could you please also clarify which stability issues are fixed and how they relate to this problem?

Thank you.

Please have the common courtesy to verify the bug against upstream components when you open an upstream bug. You driver components are over 18 months old and have known issues that match your description.

I understand your point, but I'm running a business laptop here. I'm not willing to just try out a major upgrade to e.g. Ubuntu 12.04 with a random chance of solving it. Ubuntu 12.04 is far too young to start working on, it's not stable yet. But if you can point me to the right software versions then I have a better understanding of the source of the problem and the chance of actually solving it. Thank you.
