Bug Description
Binary package hint: xserver-
X-Server freezes at random occasions on Dell D620 with Intel 945 and Ubuntu 9.10 (Karmic). For details on the configuration see attached files. No problems on same hardware when using Jaunty.
Problem is independent of whether compiz is installed and used.
Problem often occurred while scrolling in GNOME terminal. Here it is also observed that sometimes part of the window is not shown correctly (just some pixels).
Running server in debug mode following error message has been obtained after crash using intel_gpu_dump utility:
Buffer size too small in MI_STORE_DATA_INDEX (2 < 3)
Possibly duplicate of following tickets: 424613 (no activities in last weeks).

We have had several reports of freezes (GPU hangs) on i945 chipsets /wiki.ubuntu. com/X/Lucidi945 Freezes . There is a list of test
(945G, 945GM and 945GME, all of which uses the GMA950 graphics core)
in Karmic. I would like to get some testing going so that we may
identify the cause and give upstream all the information they need
(and possibly some they do not need) so that they can fix this before
Lucid is out. I have set up a wiki page to coordinate the effort:

that I think will be useful in order to isolate where the problem is
and a table where you can fill in your test results. If we're lucky
there is only one underlying problem, and we will probably get
consistent test results. Otherwise, different test results may group
the problems in different categories.
I realize that doing all the tests can be quite time consuming (it
calls for tests on both Karmic and Lucid), and if you are only able to
do some of the tests it would be nice if you could fill in those cells
in the test result table.
My initial guess is that the bug is in mesa, since it seems to be
related to 3D operations. It would be nice if we could also get some
testing of different mesa versions, but I'm not aware of any that are
pre-built yet.
