Output of lspci

I _NEVER_  use any non-free binary blobs.  I'm using only the drivers that come
with X.org
Comment 3 Matěj Cepl 2007-01-26 11:31:22 UTC 
Can we get your /etc/X11/xorg.conf as well, please? And you can also try to
restart X without any such file whatsoever, and send us report (with
/var/log/Xorg.*.log files, of course) what happens.

Thanks a lot.

My xorg.conf

My basic xorg.conf. Nothing fancy.

Xorg.0.log, after renaming tdfx_dri.so

Looks not much different than with tdfx_dri, except for the actual complaint
that the file is missing.

After renaming tdfx_dri and starting X, Myth appears to be working.  Looks like
this module is not absolutely necessary for hardware acceleration, at least it
is not required by mythtv.
Comment 6 Sam Varshavchik 2007-01-26 12:12:02 UTC 
Making an attachment did not change this bug's status, checking if a plain
comment does the trick.  Ping.
Comment 7 Adam Jackson 2007-01-30 00:48:48 UTC 
Mmm, looks like a real bug in the tdfx dri driver.  Really need to hook up some
addr2line action on the backtrace output though.  Will take a look.
Comment 8 Sam Varshavchik 2007-01-30 01:01:41 UTC 
fwiw -- tdfx_dri in the last FC4 x.org errata worked fine.

Shouldn't be too many changes in the driver for these old cards, since then.
Comment 9 Adam Jackson 2007-04-05 18:48:38 UTC 
Fixed in rawhide.  tdfx driver probes for Glide3 during CreateContext, not
during CreateScreen, and then the DRI core assumes the context private exists. 
It doesn't when glide3 isn't present, and you segfault.
