Description of problem:
3D screensaver caused lockup of Xserver. My configuration:
Compaq Evo D310vm
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. run xscreensaver-demo
2. select any 3D screensaver (e.g. AntSpotlight)
This happens 100% with the latest Arjan's kernel and sporadically
happened with older kernels. It happen with latest xorg-x11 and with
older XFree86 releases too. That makes use of 3D graphics with Intel
8x5G chipsets impossible with 2.6 kernel.
There were similar bug reports in bugzilla:
But they lack some information and I prefer to open it as new with

I fixed one bug in the i830 drm code (doubtless there are more); do
later kernels work better for you ?
Nope :-( The same story.
Latest kernel hit the spot :-) It works now.
I will watch if that bug won't show again sporadically and I'll report
it here later.
Unfortunately it still locks-up sometimes during Xserver startup. But
it's not related to 3D screensaver anymore and it's fairly usable now.
I've attached new logs.

Well, recent kernels broke it again:
But now it locks-up cold, I can't even shutdown system cleanly.
Hitting power button don't work anymore as it did before (I have
acpi=on and acpid running). And so it was not possible to get log
messages because they were lost.

Unfortunately it doesn't work with kernel-2.6.5-1.349 either, sorry.
ok 350 has this fixed 99% sure; I found out my testbox actually has a
865 chip which gets visible when I remove the AGP radeon ...
Yes, you are right, kernel-2.6.5-1.350 actually has this fixed. Thank
you very much!
I'm running Fedora Tettnang release as downloaded 2 weeks ago, and
this problem still seems to be there except it comes up more randomly.
And given that I run the machine 24x7 and have only seen the problem
when the saver kicks in, I have to assume that it only locks up the
machine if you try to use the machine while the particular SS is
active. i.e. if you let the problem SS run it's course (e.g. while
I'm gone all day) and let the next one start, it's fine. Maybe that's
an invalid assumption.
I've had it happen twice now. Sorry, don't recall which saver it was
either time. First time when I moved the mouse to deactive the saver
text appeared in the top left of the screen. i.e. it was console text
coming out over top of the X server as though X were not even running
if you get what I mean. I could still move the mouse and alt-tab
windows - for a bit. Then things locked up completely. But when I
hit the power button X came down and then I had the regular clean
Linux shutdown with all the "blah blah blah ..... [OK]"
The second time was just a few minutes ago and there was no console
text coming through, and it was hung tight from the beginning and the
power button seemed to initiate a shutdown but I didn't get all the
"blah blah blah ..... [OK]" - a few lines of shutdown text came up
then the power went out. On reboot filesystems were clean though.
I've got an Nvidea Gforce (440 I think) video card, and an ASUS mobo
either A7N8X-X or A7V8X-X don't recall of the top of my head.
Dunno if this should reopen this bug or if there is somewhere else for
this to go. My apologies if I did the wrong thing but this was the
closest I could find.
I'm seeing what looks like the same problem (X lockup on 3D
screensaver) under a stock FC3 with a 2.6.9 kernel, ATI Radeon card.
It did not occur under FC2.
