Description of problem:
On a Dell Dimension 8600 with the i865G chipset with integrated
graphics, the graphic display initially refused to start at anything
but 640x480 resolution.  I discovered
http://www.chzsoft.com.ar/855patch.html which solved the problem
somewhat, but after updating to BIOS A10 (released 29 June) the patch
no longer seemed necessary.  I noticed a dramatic improvement in
tuxracer speed after the BIOS update, although there are significant
screen artifacts while playing tuxracer (but not in anything else I've
noticed.)  When leaving the machine on for long periods (overnight)
the X window system crashes with the following error and doesn't seem
to be restartable (it encounters the same error) without a reboot.

This failure is happening on some xscreensavers.  I've been able to
reproduce it at will with boxed.  Knowing that, it seems this is a
duplicate of 119705 which is incorrectly marked closed (It is not
fixed by the kernel stated there, or it's rebroken in later kernels.)
 Either way, it's not closed in rawhide.

I'm having the same problem with the same videocard on an IBM Machine
S50 Intel865G Video Card.  It happens even with use sometimes.  The
taskbar just froze and unable to respond also.

I'm experiencing the same thing occasionally on my box as well. It's
an old Dell GX110 with an Intel Corp. 82810E DC-133 CGC video controller.

The Xorg.0.log file ends with the following. I may be able to help out
with this issue, though I don't know very much about the internals of
x.org's source code. It would be nice to know what's causing it.

Comment 6 Mike A. Harris 2004-08-31 13:22:59 EDT
The Intel driver included in rawhide currently, which is from
X.Org 6.8.0RC3 (, is much newer than the one included
in FC2.  Also, a brand new kernel DRM driver (i915) for Intel video
is now in our rawhide kernel.  The new DRM replaces the i830 kernel
module, and supports all Intel hardware from i830 upward.

Please test install Fedora Core 3 test1 and update to current
rawhide packages, or alternatively you can wait for Fedora Core 3
test2 to be released and upgrade to that.  It's also possible to
upgrade the kernel, xorg-x11 and some other packages on top of
Fedora Core 2, however that's more experimental and may not work

Once this problem has been tested with the current rawhide kernel
and X packages via one of the methods above, if the problem persists
still, please file a bug report in X.Org bugzilla so the Intel
video driver maintainers are aware of the problem and can investigate
if a solution is possible, or if it is a BIOS related bug.  X.Org
bugzilla is located at:  http://bugs.freedesktop.org in the "xorg"
component.  If you file a report there, we will track the issue
upstream for you as well, if you paste the bug URL here.

Thanks for testing Fedora development.
