Description Al Scandar Solstag 2006-05-10 15:10:37 UTC 
Configuration:

Matrox G450 AGP
Linux 2.6.17-rc3
Gentoo xorg-x11-7.0-r1

Steps:

1 make sure dri is enabled
2 xinit
3 optionally disable dri
4 xinit -- :1
5 system halts

I have tried in xorg.conf all comment/uncomment combinations of "dri", "glx" and
"AGPMode 4" (I'll attach my xorg.conf), and have tried running parallel
instances of glxgears to see if it reproduced another bug I saw, but everything
works fine, except when the exact steps above are taken.

hugs,
ale

Created attachment 5591 [details]
solstag's current xorg.conf

all I did to reproduce the bug was comment/uncomment the lines reported.

Are you running the kernel supplied dri or the external one?
If you are running the kernel based try and download and install the one from
http://dri.freedesktop.org
Comment 3 Al Scandar Solstag 2006-06-18 22:04:29 UTC 
I was running the kernel supplied one, but today I compiled this one:

# dristat -v
/dev/dri/card0
  Version information:
    Name: mga
    Version: 3.2.2
    Date: 20060319
    Desc: Matrox G200/G400

From Gentoo's package "x11-base/x11-drm-20060608"
So I believe it is fairly new, and the problem persists.

As a note, I'm also now using:
Linux 2.6.17
Gentoo xorg-x11-7.1

Sorry about the phenomenal bug spam, guys.  Adding xorg-team@ to the QA contact so bugs don't get lost in future.
Comment 5 Al Scandar Solstag 2007-03-16 21:05:44 UTC 
Ok, this seems to be fixed running the newest stuff.

xorg-x11-7.2
and
x11-drm-20070314

thanks!
