Didn't work for me either, I think it is something
about SELinux.

I think I had a problem with glx in the beginning and
fixed it. My problem was that in
/usr/X11R6/lib/modules/extensions there was the
libglx.a (part of xorg) and X was finding that instead
of the nvidia/libglx.so so I:
#cd /usr/X11R6/lib/modules/extensions/
#mv libglx.a xlibglx.a
#ln -s nvidia-graphics-1.0-7174/libglx.so.1.0.7174
libglx.so
#telinit 3; telinit 5
#grep -i glx /var/log/Xorg.o.log
(II) LoadModule: "glx"
(II) Loading
/usr/X11R6/lib/modules/extensions/libglx.so
(II) Module glx: vendor="NVIDIA Corporation"
(II) Loading extension GLX
(II) Loading extension NV-GLX
(II) Initializing extension GLX
I just installed 6629 via apt-get and now I have my
1080i modeline working, thanks. I changed my ln -s
line above to:
ln -s nvidia/libglx.so libglx.so
that way it will still work if I ever change nvidia
drivers again.
