Try it with LIBGL_DEBUG=verbose.

Looks like everything works OK in libGL but the screen or context creation fails
silently inside the 3D driver. Someone who can reproduce the problem needs to
debug the driver and find out what's wrong.

Well, I do know my way around C++, but I'm a java developer, so haven't played
with it in awhile. If you can give me instructions and point me in the direction
of docs, I'd love to play with it again. :)

Thanks!

Erm, I wasn't paying attention. You're still running Xorg 6.8.2? Before you go
into debugging the problem, try if the latest drivers fix this issue. Take a
look at
http://dri.freedesktop.org/wiki/Download#head-55420c59a1c2e9a70f07a6fa02f0d228ffb87b76.
In particular pay attention to the section "Upgrading to Xorg 6.9" before
installing the binary snapshots. Then download and install the latest common and
i915 snapshots.

Upgraded to latest snapshot, now getting error when running "export
LIBGL_DEBUG_VERBOSE=y; glxinfo"

Here's the dump:
ERROR!  sizeof(I830DRIRec) does not match passed size from device driver
libGL warning: 3D driver returned no fbconfigs.
libGL error: InitDriver failed
libGL error: reverting to (slow) indirect rendering

What's an I830DRIRec? :)

In my xorg.conf, do I still use the i810 as the display driver?

Thanks!

I830DRIRec is a data structure shared by 2D and 3D driver. If the size doesn't
match that probably means that you're using a bad combination of 2D and 3D
drivers. Make sure that both are from the i915 snapshot you installed. After
installing the snapshots, you need to kill the Xserver, unload the i915 and drm
kernel modules and restart the Xserver. On the Xserver side i810 is still the
right driver. BTW, I'm assuming you're not using a 64-bit OS?

Nope - no 64bit OS. I've tried that, and am getting the same error. Here is what
I did.

init 3
/sbin/rmmod i915
/sbin/rmmod dri
reran i915-200.../install.sh
init 5

Any other thoughts? Or am I doning this wrong?

Check your Xorg.0.log file to find out which i810_drv.so it is loading. It
should load the one from /usr/X11R6/lib/modules/drivers/. Also run
LIBGL_DEBUG=verbose glxinfo. It should tell you, which i915_dri.so it is
loading. It should load the one from /usr/X11R6/lib/modules/dri/. If any of
these don't match, try to find out why. Check the Files section in your
xorg.conf and make sure that the environment variable LIBGL_DRIVERS_PATH isn't
pointing to some strange location. Also the driver binary i810_drv.so and
i915_dri.so files in /usr/X11R6/lib/modules/... with the ones in the snapshot to
make sure that they were copied correctly during installation.

The log file and the verbose output are both pointing to the correct place. I
didn't know the best way to verify the drivers, but they are the same size as
those found in the package. LIBGL_DRIVERS_PATH is not set in the environment,
and under the Files section of the xorg.conf are only paths to fonts.

One thing that might be the cause though, is my install of X. I started from the
upgraded FC4 install, and just installed the xserver package and the i915 driver
package per the wiki instructions. I poked around a bit, but those are the only
two binary snapshots that I saw on that link. Do I need to install anything else?

Thanks!

Have you installed the "common" snapshot?

Right - yes I did. So Common, Xserver package and DRI snapshot are the ones
installed.

Could you attach an updated Xorg.0.log?

Response to comment 17

As it turns out this problem is caused by the snapshot builds using outdated
Xorg 6.9 sources that are incompatible with the current i915 driver from Mesa.
i915 snapshots 20060123 and older should still be OK.

Alan Hourihane updated a version check in the Mesa driver so that it will report
a more useful error message. Closing this as FIXED.

There is still a bug in the snapshot build. It should use the modular Xorg. But
that's a different issue.
