glxinfo with nomodeset
Description of problem:
3D acceleration doesn't work properly with Radeon 9500 AGP.
Version-Release number of selected component (if applicable):
Name : kernel
Arch : i686
Versione : 184.108.40.206
Release : 134.fc10
Name : xorg-x11-drv-ati
Arch : i386
Versione : 6.9.0
Release : 61.fc10
Name : mesa-dri-drivers
Arch : i386
Versione : 7.2
Release : 0.14.fc10
glxinfo reports the "normal" R300 string under "OpenGL renderer string". Don't remember it exactly now because I have too many issues with KMS so I'm not using it.
glxgears starts and then freezes the computer after roughly one or two seconds.
with "nomodeset" kernel option glxinfo has:
OpenGL renderer string: Software Rasterizer
(complete glxinfo attached)
glxgears runs but reports only ~80fps.
Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.
Please attach your X server config file (/etc/X11/xorg.conf, if available) and X server log file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link below.
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.

This xorg.conf is generated by system-config-display when choosing 1280x1024 as the default resolution; I made no more modifications. However Xorg works fine also without xorg.conf (with a higher default resolution).

glxinfo with KMS activated
This bug is fixed for "nomodeset" with kernel kernel-220.127.116.11-163.fc10 from Koji: glxinfo reports the correct string and glxgears is accelerated.
However I experienced a crash (with monitor standby) a short time (1 min) after enabling Kwin's OpenGL effects... I'm going to try with some 3D games.
Cannot test with KMS activated because of this other bug:
I can confirm the freeze one second after starting glxgears with KMS enabled also with kernel "-163".
So, to resume:
- 3D is now fixed with "nomodeset" and kernel "-163";
- glxgears locks after 1 sec with KMS and kernel "-163".
So actually they were separate issues.
The issue with KMS still applies in F11: I tried the live CD, clicked on the "enable desktop effects" button in Gnome and I got a total lock up (the mouse cursor was still).
Fixed in F11 with Mesa 7.6 in updates-testing:
Nome : mesa-dri-drivers
Arch : i586
Versione : 7.6
Release : 0.1.fc11
So this still applies only to F10 (F9 hasn't got KMS).
This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '10'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 10's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 10 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
