I have recently installed a fresh gentoo linux setup. When installing the nVidia
drivers according to the instructions on the web-site, I encountered problems
getting OpenGL programs to run correctly. glxinfo returned "Direct rendering:
no", frame rate was bad and some programs wouldn't run. Great help from people
at #gentoo-irc and a "ldd -d glxgears" revealed that the libGL.so drivers used
by the applications were the ones that come with XFree86. ld loaded the drivers
from /usr/lib, and there were symlinks to /usr/X11R6/lib/libGL.so from there.

I noticed from the ebuilds that it was made a point to put /opt/nvidia/lib
before /usr/X11R6/lib in ld.so.conf to avoid this problem, but as (to my
knowledge at least) ld loads by default from /usr/lib first even though /usr/lib
isn't listed in ld.so.conf, there are still issues with the default setup.

To get around the problem I changed the libGL-symlinks in /usr/lib to point to
the nVidia provided ones, and all problems were resolved.

Another solution (and prehaps better) might be to remove the libGL-symlinks in
/usr/lib alltogether, so that control over which drivers is loaded can be
reestablished in ld.so.conf.

Best regards
