[ATrpms-users] Re: Quake3 Broken After nVidia Upgrade

Thanks Axel,

But this still doesn't work for me.  I deleted the libGL entries from 
the /usr/lib/tls directory.

And when I use nvidia-graphics-switch, the lines in ld.so.conf get 
replaced properly.  Like right now I'm using 5336 and my ld.so.conf file 
looks like this:

/usr/lib/nvidia-graphics-1.0-5336
/usr/X11R6/lib/nvidia-graphics-1.0-5336
/usr/X11R6/lib
/usr/lib/sane
/usr/lib/mysql
/usr/lib/qt-3.3/lib

Here is the output of glxgears:

[root at homer root]$ nvidia-graphics-switch 5336
0: nvidia: loading NVIDIA Linux x86 NVIDIA Kernel Module  1.0-5336  Wed 
Jan 14 18:29:26 PST 2004

[root at homer root]$ ldd `which glxgears` | grep libGL
        libGL.so.1 => /usr/lib/nvidia-graphics-1.0-5336/tls/libGL.so.1 
(0x00bc1000)
        libGLcore.so.1 => 
/usr/lib/nvidia-graphics-1.0-5336/tls/libGLcore.so.1 (0x001ef000)

[root at homer root]$ nvidia-graphics-switch 6106
NVRM: loading NVIDIA Linux x86 NVIDIA Kernel Module  1.0-6106  Wed Jun 
23 08:14:01 PDT 2004

[root at homer root]$ ldd `which glxgears` | grep libGL
        libGL.so.1 => /usr/X11R6/lib/tls/libGL.so.1 (0x00111000)

Note that the 5336 reports the correct output, but Quake3 still won't 
start, and reports the exact same error as before.  The Quake3 "wrapper" 
script doesn't mention anything about over-writing library paths:

#!/bin/sh
# Needed to make symlinks/shortcuts work.
# Wrap Quake III binary
cd "/usr/local/games/quake3"
./quake3.x86 $*
exit $?

Here is something interesting from the Quake3 README:

NOTE:  Linux Q3A will try to load "libGL.so" before using other drivers,
and it will ignore libraries from the quake3/ directory if executed
with root privilege. This can cause problems if you have a software or
third party OpenGL driver installed.

You can specifically target e.g. the included 3dfx based Mesa driver,
by using the following command line:

        quake3 +set r_gldriver libMesaVoodooGL.so.3.2

Do you think I could specifically target the nvidia driver with the 
above command?  If so, what would be the driver file to name?

Thanks for the help!
