Xorg and DRI problem, xorg.log and glxinfo disagree [fixed]

[kliment]

just switched to xorg, did the opengl-update to xorg and tried running it. it loads the driver for my voodoo 4 just fine, states that DRI is up and running in the xorg log file, but when I try to run glxinfo I get the message that DRI is disabled. Any Ideas?

$ glxinfo |grep render
direct rendering: No
OpenGL renderer string: Mesa GLX Indirect

same result if run as root.

in the xorg log file, I have
[snip]

[snip]
(II) TDFX(0): [drm] installed DRM signal handler
(II) TDFX(0): [DRI] installation complete

to me that would indicate that everything is working fine.
yet glxinfo disagrees... and opengl applications are all using software rendering (very slow)
The same card, under the same config, worked fine in xfree86

The problem was with glide, which was apparrent after running

LIBGL_DEBUG=verbose glxinfo

which yielded the following errors:

libGL error:
can't find Glide library, dlopen(libglide3-v5.so) and dlopen(libglide3.so.3) both failed.
libGL error:
dlerror() message: /usr/lib/libglide3.so.3: undefined symbol: _trisetup_Default_win_nocull_valid

the problem is a missing glide library. reemerging glide does not help.
the solution is as follows:
$ wget http://dri.sourceforge.net/res/voodoo5/x86/libglide3-v5.so
# cp libglide3-v5.so /usr/lib
# ldconfig

after which dri works as expected.

thanks, but ... why not file a bug report? it's better let the developers know what happened and fix it in the ebuild.

holy sh*t, thats exactly the problem I'm looking for . I have got this prob yesterday, and haven't been able to solve it. But hopefully this rhread will help . I'll try it this evening, and post a reply wether I had success or not

[GungHo]

no success

I had a closer look to my errormesg, and saw that in my case not libglide3-v5.so is missing, but libglide3-v3.so. Could not find libglide3-v3.so on my box or in the net. also making a symlink from this libglide3-v5.so to libglide3-v3.so didn't help, also re-emerging of libglide3-3.10-r3 or libglide3-3.10-r4 didn't help. I also reemerged my whole xorg-x11-6.7.0-r1, but it didn't help at all .

The whole sh*t worked for a long time, with several versions of XFree and it worked also after I moved to Xorg, it stopped working after I updated libglide3 to a newer version.

Here are some messages:

My box uses gcc-3.3.3, a self patched 2.4.27 kernel with the patchset of Con Kolivas (it had worked with this kernel before updating libglide3 ).

Who is willing to assist me tracking this thing. Otherwise I'll file a bugreport.

Thanks in advance

The glide-v3 package in Gentoos repository is buggy, definitively.

I d'loaded the binary package from http://glide.sourceforge.net/ , moved the 2 files libraries into /usr/lib

-rw-r--r-- 1 42 root 717198 Aug 28 2003 /usr/lib/libglide3.a
-rw-r--r-- 1 42 root 585607 Aug 28 2003 /usr/lib/libglide3.so

ran a 'ldconfig -v' and all worked well. The framerate of glxgears went up approximately 4 times, glxinfo also works well:

----
direct rendering: Yes
...
OpenGL vendor string: VA Linux Systems, Inc.
OpenGL renderer string: Mesa DRI 20021125 Voodoo3 x86/MMX/3DNow!/SSE
OpenGL version string: 1.2 Mesa 5.0.2
----

Don't know how to exactly locate this bug inside the sources, otherwise I'd like to volunteer tracking down the bug/s

for me (with a voodoo 3000)

Hi plasmagunman,

correct me if I'm wrong, but this means to compile glide-v3 without 3dnow support ?!

If this is correct, wouldn't it be better to automate this, that whenever glide-v3 is emerged, that this is done without 3dnow support by storing
