Hi jazz2rulez,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

here they are:

Here it is:

aquilinux, Thank you for providing the log files, but 965GM is a different chipset from 855G, so it is probably not the same bug, even though they look similar. Please file a separate bug report, unless you find a bug where the same problem is reported for the 965GM chipset.

Could be that the bug affects more than one chipset.

Usually bugs in the driver don't affect such different chipsets, but this actually looks like a bug in mesa, and not in the driver. The error comes from Mesa-7.2/src/mesa/drivers/dri/common/dri_bufmgr_fake.c in the source package mesa (http://packages.ubuntu.com/source/intrepid/mesa). It's line number 987 in http://cgit.freedesktop.org/mesa/mesa/tree/src/mesa/drivers/dri/common/dri_bufmgr_fake.c?h=mesa_7_2_branch&id=75b8d0209c62e696714abf16782804c5a14159cf .

There has been one update to this file after mesa 7.2 was released (http://cgit.freedesktop.org/mesa/mesa/commit/?id=75b8d0209c62e696714abf16782804c5a14159cf) fixing a bug http://bugs.freedesktop.org/show_bug.cgi?id=17705 , but I don't know if that bug is related to this one.

This could be the upstream bug: https://bugs.freedesktop.org/show_bug.cgi?id=15639

See bug #252094, at the bottom it contains instructions to upgrade several package, resulting in improved performance but also for me fixing the bugs reported here (requires a newer kernel and installing ppa packages, caveat emptor!).

[This is an automatic notice.]

We'd like to forward your bug upstream, however upstream requires
that you first test it against their newer driver code.

To save you the effort of building the driver from source, we've built
packages for the driver and its new dependencies.

So you have a couple options:

 1. Download and test .debs for intrepid, from:
     https://edge.launchpad.net/~intel-gfx-testing/+archive

 -or-

 2. Download and test the Jaunty alpha-2 (or newer) Live CD,
     (which includes a beta of the new xserver 1.6 as well).
     See http://cdimage.ubuntu.com/releases/9.04/ for ISOs

Thanks ahead of time! You can simply reply to this email to report your
findings.

P.S., if you wish to forward your bug upstream yourself, please follow
these directions to do so:
  http://intellinuxgraphics.org/how_to_report_bug.html

Bug still exists with intel driver 2.51 and intrepid 64bit

hth, Stephan

Thanks for testing; this should go upstream. Setting to Triaged for now.

FWIW I ran into this exact error message on my Acer Aspire One (945GME) but in my case installing the intel-gfx-testing package fixed the error.

[No need to have this open against -intel since it's really a mesa bug.]

According to the upstream bug, it is fixed with mesa-7.2 and the new GEM stuff. So please test against Jaunty, which I think should have all the requisite fixes now.

Which package actually provides mesa? I have looked on Intrepid at the packages libgl1-mesa-dri and libgl1-mesa-glx, both of which are version 7.2 and I still have this problem.

I have also updated to the files to those in the PPA and still no joy.

Mesa is a source package which provides the source for many binary packages, including the two you mentioned. http://packages.ubuntu.com/source/intrepid/mesa
Mesa 7.2 (or rather a RC IIRC) has been in Intrepid all along, but "the new GEM stuff" hasn't.

Which PPA have you updated to? I assume it's one of these two:
https://launchpad.net/~xorg-edgers/+archive/ppa
https://edge.launchpad.net/~intel-gfx-testing/+archive/ppa

At least the last of these two don't have the newest drivers that are currently in Jaunty. The easiest way to test is probably to download the alpha-4 Jaunty LiveCD from http://cdimage.ubuntu.com/releases/jaunty/

Apparently this should be fixed in current jaunty. Reopen if untrue.

So this has been marked fixed but the only fix that appears to be available is "Upgrade the Jaunty alpha or compile the entire X.org stack by hand." Which really doesn't seem like a reasonable fix for someone interested in a stable system (i.e. Intrepid).

There is no easy way to fix this in intrepid, and yes, the developer
resources are now better spent stabilizing the upcoming release than
improving the soon-to-be-previous release. Btw, Jaunty is now in beta
and due to be released this month. Jaunty is probably much more stable
than Intrepid with a self-compiled Xorg stack, since a great amount of
work has been put into stabilizing the Jaunty version.
