Public bug reported:
This bug concerns all versions of the nvidia-packages I have tested so
far, actually since ubuntu 8.something...
If I install the proprietary nvidia drivers, I can properly set up my
xorg.conf and the Xorg driver as well as the kernel module load
correctly. However, when using unity or anything requiring libglx.so, X
simply crashes. The reason is that X is loading the wrong libglx.so:
grep glx /var/log/Xorg.0.log
[ 11312.722] (II) "glx" will be loaded. This was enabled by default and also
specified in the config file.
[ 11312.722] (II) LoadModule: "glx"
[ 11312.722] (II) Loading /usr/lib/xorg/modules/extensions/libglx.so
[ 11312.722] (II) Module glx: vendor="X.Org Foundation"
My first solution was to move /usr/lib/xorg/modules/extensions/libglx.so
out of the way and to replace it with a symlink to /usr/lib/nvidia-
VERSION/xorg/libglx.so. However, as you might imagine, this quick-and-
dirty fix has to be redone each time that MESA gets updated, as my
symlink is destroyed. I have now found a better solution, which consists
in telling Xorg where the right library is in /etc/X11/xorg.conf
Section "Files"
ModulePath "/usr/lib/nvidia-VERSION/xorg"
ModulePath "/usr/lib/xorg/modules"
...
EndSection
nvidia-VERSION has to be replaced by the proper nvidia version (such as
nvidia-current). As a result, X loads the right libglx.so.
This solution could be included in all nvidia- packages, so that the
problem does not occur any longer. I have found other bug reports from
other distributions about this, but most are solved by moving libglx.so
out of the way.
Just for information, here's some details about my system:
