Random Xorg freeze on Acer eMachines eM350 (Intel GMA3150)

[Oleg Shparber]

Binary package hint: xorg

Xorg rangomly hangs on my netbook while user X-session is active. Disabling Compiz decreases number of hangs, but they still occur sometimes.

No hangs ever noticed when GDM login screen is on and during working on external monitor (even with enabled Compiz). Kernel update from Kernel-PPA and installation of intel drivers from https://launchpad.net/~glasen/+archive/intel-driver didn't helped.

Tried to follow https://wiki.ubuntu.com/X/Troubleshooting/Freeze (Advanced: How do I tell if my GPU has really locked up?) but it didn't detect any abnormalities.

Ubuntu 10.10 Beta has the same bug.

[Oleg Shparber (trollixx)]

Same with version 2.13 of intel drivers. Hangs even when booted from Maverick's LiveCD.

[Oleg Shparber (trollixx)]

Some new info. Now I catched several hangs during work with external monitor connected. Ubuntu 10.10, intel drivers 2.13.901 from glasen repo.

And finally there's some info in /var/log/messages exactly before hang:

[plux (plux2005)]

I have the same problem on a Foxconn Netbox nt525 with Intel GMA 3150. Have to change to vesa driver to get it working without freezes.

[bugbot (bugbot)]

This bug appears to involve a freeze of Xorg, probably due to a GPU
lockup in the kernel drm code, in a version of Ubuntu before
natty (or we couldn't determine the version from the report).

The X team has been investigating GPU lockups in Intel's video driver
during the natty development cycle. Many of these issues are now either
resolved or at least well understood. There are also better tools for
capturing and diagnosing these problems, but these tools are either
unavailable or incomplete in older versions of ubuntu, so debugging this
issue on pre-natty versions is unlikely to be productive. We're closing
out the bug report for this reason.

However, you may not yet be ready to upgrade to natty. It turned out
that a large number of these freezes were solved by updates to the
kernel. Thus, updating your kernel may be a workaround for you.
Updated kernel packages are available a variety of places, such as:

  http://kernel.ubuntu.com/~kernel-ppa/mainline/

If you find a newer kernel fixes it, and think the fix should be
backported to earlier Ubuntu versions, please file a request against the
linux kernel in Ubuntu, indicating the broken and the fixed kernel
versions.

If it does not fix it, and you do not wish to upgrade to natty, please
follow up through technical support channels (e.g. http://askubuntu.com
is a good place for free support for older Ubuntu versions).

On the other hand, if you find after upgrading to natty and updating to
latest that you still experience GPU lockups, please reproduce the
problem, ssh into the frozen machine, and collect the file
/sys/kernel/debug/dri/0/i915_error_state and the output of 'dmesg >
dmesg.txt', and attach both to a new bug report.
