Description William M. Quarles 2004-01-16 06:10:00 UTC

Description of problem:
I saw a message on the GATOS project mailing list saying that there is
a major bug in XFree86 4.3: AGP cards are running slower than PCI
cards.  The best test of this is a 3D game.  I tried the Linux game
Chromium out, and sure enough the game wouldn't work properly; it
behaved as though the system did not have 3D acceleration.  I decided
to install Red Hat Linux 8.0 on a different hard drive in my computer
and see if the acceleration was restored by using XFree86 4.2.1, and
in fact the speed was restored.

If this was a known issue when Red Hat Linux 9 was released, I don't
think XFree86 4.3 should have been part of the release.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Install Red Hat Linux 8.0 with Chromium on a system with an AGP card
with DRI support
2.Play Chromium
3.Upgrade to Red Hat Linux 9, or use a similar computer running Red
Hat Linux 9.0
4. Play Chromium

Actual Results:  Chromium works on Red Hat Linux 8.0, but not on Red
Hat Linux 9.

Expected Results:  Chromium should run smoothly on both computers.

Additional info:

My computer has the following:
Dell Dimension XPS T-series with Intel 440BX chipset
Pentium III 1.1 GHz
ATI All-In-Wonder Radeon AGP video card (running at 2x)

I screwed up, this is fixed in XFree86 as Red Hat distributes it, the
problem is likely in the GATOS XFree86 software for Radeons.

more specifically, I should say....  Don't file bug reports to
Red Hat, if you are using _any_ 3rd party video drivers or kernel
modules, be they open source or proprietary.  ANything we do not
ship is explicitly unsupported by us, and only supported by the
people who provided it to you, or the community.

Comment 4 William M. Quarles 2004-01-23 01:51:20 UTC
I thought I tried the Red Hat drivers also, I must have made a
mistake.    I'm sorry for the trouble.

In any case, I troubleshot the heck out of that problem and opened a
wide discussion on the list, which is now Bug 114125.  And yes, it is
a 3rd party driver, but a Red Hat update broke the compatibility.
Then again, your probably already got that e-mail.
