Hello,
I have been trying to use Zephaniah E. Hull's Debian DRI packages
(versioned 2001.04.01-1) with my 8MB AGP G200 at 640x480. I've been
using the kernel module from DRI CVS.
Very soon (between 3 seconds and a minute) after starting any
XScreensaver GL hack, or QuakeForge-gl, that process segfaults in
__driCreateScreen. All of the GL XScreensaver hacks work flawlessly with
plain mesa. The backtraces seem worthless, suggesting that function is
called from strcpy() in some cases. I have had the same results when my
G200 was sharing an IRQ with my ethernet card and when I gave it its own
IRQ.
Several months I tried using DRI under stock XFree86 4.0.1 and had the
same lack of success. The only difference back then was GL use was more
likely to lockup my machine after a few seconds than cause a segfault.
With April 1st's DRI, I cannot hose my machine with it, but can't get it
to work consistantly either.
The output of glxinfo is below.
