Description Ferry 2008-08-21 03:02:13 UTC
Hi there,

ever since the last couple of versions of the intel driver X crashes on me. Sometimes this happens several times a day, some times not for days. Don't appear to be doing the same. It can happen with little or no apps running, but mostly I have a lot of stuff running. It happens with 2 monitors, or just 1.

Original bug report is here:


Still need to enable the ModeDebug. Will report back once I have useful output from that.

It concerns my laptop, a HP/Compaq n6320.

More details follow.

Sorry about not responding this long. Some how ever since I enabled the
ModeDebug (and this is all I changed to X) it doesn't crash anymore (well not
yet anyways). Kind of strange, it never ran this long without crashing w/o the
debug mode.

Do have 2 other problems, don't know if they are related. They seem opposites
of each other too.

If in X i switch to console with Ctrl+Alt+F1 and then switch back, I usually
don't get any screen anymore (it remains black). Can switch back to console
that's fine.

If the laptop suspends to memory and comes out of it, X will show just gray
with pale colored lines. I have to switch to terminal, the terminal will stay
black, and switch back to X. X is usually fine then, but the consoles don't
show anymore.

It finally crashed again. I'll attach the Xorg.0.log.old

Sorry I haven't replied to this one until now...

There are a few other, similar 945GM reports open at the moment, but none of them have a reliable set of steps we can use to reproduce the problem.  Both the 3D driver and the render acceleration code make heavy use of the GPU via the ring, so disabling one or both of those might make the problem go away, can you give that a try?
Comment 10 Jesse Barnes 2008-09-24 09:53:09 UTC
Marking this one as a dup of 14263.  If we ever get info indicating that they're separate we can file another bug...  Last comment still stands though, we need to isolate this and find a way of reproducing it.
