[i915g] X crashing while watching video (Server Kernel)

[cyracks]

Binary package hint: xorg

While watching video ( xine, vlc,... ) it hapens that X crashes and I am thrown to the login window. Especially when I move from one time frame to another.
This problem occurred after the upgrade from 8.10 to 9.4

You are using the server kernel, which uses PAE. GEM is not compatible with PAE and is therefore disabled.
That means you get the fake bufmgr, which is too small to handle video correctly (fake bufmgr (1024 kB)).
Unfortunately, allocating more memory for the fake bufmgr was tried during jaunty development, but was causing other problems.
If you want to play video, you should use the -generic kernel instead of the -server kernel.

As suggested I installed generic kernel and I think the problem is much less frequent, but if I quickly move from one time frame to another I still manage to crash X server.

How come that the server kernel worked with 8.10 without any problem.

[This is an automatic notification.]

A new major version of the -intel driver is now available in Karmic.

This version includes a major reworking of the acceleration
architecture, which resolves a huge number of issues. We do not know
whether it resolves the issue you reported.

Would you mind testing Karmic Alpha-2 and seeing if it is still a
problem? CD ISO images are available here:

  http://cdimages.ubuntu.com/releases/karmic/

If the issue can still be reproduced on karmic, please report here with
your findings, and attach a fresh Xorg.0.log from your test, and we will
be able to forward the bug upstream.

Otherwise, if the bug no longer exists in Karmic, let us know that as
well.

In the off chance you encounter different bugs while attempting to test
Karmic, please report those as new bug reports.

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.
