X.org X11 and NVIDIA OpenGL problem

Rebuild the srpm they use to create the rpms.

For me, the livna.org rpm rebuilds well.. however you will have to modify it slightly to remove explicit dependencies on XFree86 in the specfile. Hopefully there will be a corrected version released soon if you don't know how to go about that... atm I can't construct a quality example to lead you through it.

Well, I almost gave up on this.
I recompiled the src package provides by Livna (couldn't find the place where to remove the XFree86 dependency, but it compiled and installed smoothly with a --nodeps..), but after installing the created nvidia-glx-*.rpm and kernel-module-nvidia-*.rpm I still got that stupid relocation error (symbol _nv000344gl, version LIBGLCORE not defined in file libGLcore.so.1 ...)

This time the rpm installed the binarys in /usr/lib/nvidia (rather than /usr/lib), so I could savely move the symlink from /usr/lib/nvidia/libGLcore.so.1.5336 to the one in the tls subdir without screwing my KDE installation (see above). Guess what, it still outputted the relocation error.

I asked Andy Ritger - a support guy from nvidia - for help, but after his last, unfortunately not very helpful suggestions, he didn't replied to my answers for over a week now. So I will probably wait for livna to supply valid Fedora Core 2 nvidia rpms (since core 2 ships with basically the same kernel version I compiled myself, 2.6.5).

Hi,

I had same problem as TommyD -- an error loading GLX module.
After few desperate days I decided the problem is not in nvidia module, but somewhe else - in module loader or some library loader.

To my surprise I found a version mismatch of glibc:
(I am a newbe so the surprise was't so big )

/var/log/rpmpkgs

glib-1.2.10-10.i386.rpm
glib2-2.2.1-1.i386.rpm
glib2-devel-2.2.1-1.i386.rpm
glibc-2.3.2-27.9.7.i686.rpm <-- 686 x 386
glibc-common-2.3.2-11.9.i386.rpm <-- !!! twice
glibc-common-2.3.2-27.9.7.i386.rpm
glibc-devel-2.3.2-27.9.7.i386.rpm
glibc-kernheaders-2.4-8.10.i386.rpm
glib-devel-1.2.10-10.i386.rpm

After removing wrong packages and installation of the right one the problem was SOLVED!
ATTENTION - removing of glibc-2.3.2 (or what ever you have) will destroy your system immediately! It is better to have some alternative as Knoppix prepared.

Yours, Richard

Anybody experienced similar problems? Any help is greatly appreciated!

Btw: Am I completly blind or has this forum no search?

Hi
Sorry for my english :-/

I had this problem after upgrade my xserver-xfree86 to 4.3.0. After installation nvidia drivers I see, that /usr/X11R6/lib/modules/extensions/libglx.so.1.0.5336
and NVIDIA-Linux-x86-1.0-5336-pkg1/usr/X11R6/lib/modules/extensions/libglx.so.1.0.5336

has different size, so I simply copy this file from unpacked nvidia drivers
to my /usr/X11R6/lib/modules/extensions/ (override it)

This opperation cause, that no errors are displayed and glxgears
work correct, (~800fps in window)

I don't no why, but before this upgrade I simply installed nvidia drivers
and they work fine.

You may or may not be blind, but the search is there. The search link is on the blue horizontal separator above the flash animation. (blind people could find it too you know)

My previous responses weren't all that useful. This problem looks very much like you're loading Mesa libs in conflict. The first thing to notice.. is that GLcore should not be loading at all. Remove Load "glcore" from the config file. If you still have issues with this.. just uninstall xorg-x11-Mesa-libGL and then install the driver package. Afterwards you can get the Mesa rpm and install it back in for dependencies... just without modifying the filesystem. Do that with: rpm -i --justdb xorg-x11-Mesa-libGL
