[Dri-users] Bad textures in glquake, tdfx dri driver - Mesa 6.4.2

[Francisco L. F. <flu...@gm...>]

Hello,

I have been testing lately OpenGL games with tdfx DRI driver, both with
3DFX voodoo banshee and voodoo3.
In both cases the Linux setup is Ubuntu Dapper with Xorg 7.0/Mesa 6.4.2
and corresponding DRI drivers.
First of all, I need to patch tdfx to work, because with unpatched
sources, the driver segfaults in any OpenGL app other than glxgears
(see: https://bugs.freedesktop.org/show_bug.cgi?id=7574).
But even with the patch applied some applications don't work properly.

Compiling two different glquake engines, that are the closest to the
original game engine sources:
1. TyrQuake 0.54
(http://disenchant.net/files/engine/tyrquake-0.54.tar.gz)
2. GlQuake (http://mfcn.ilo.de/glxquake/, patch in
http://www.wh-hms.uni-ulm.de/~mfcn/shared/glxquake/glxquake.tar.gz).
and running them with the shareware data files, the textures are
corrupted, made of big blocks of random colours, with pink-like colors
more predominant.

With a Slackware 10.2 setup (Xorg 6.8.2 /Mesa 6.2.1) both engines work
flawesly.

Quakeforge opengl client (last version) does work, as far as we speak on
textures, but I can't make it to work in full screen, nor receive
keystrokes.

My OpenGL skills are close to none, but I think that the problem would
be related to the GL_EXT_shared_texture_palette extension (paletted
textures) that is used by default with drivers that support it (as tdfx
does). Quakeforge could be using another method to apply textures.
