You most likely still using the (open source) "nv" driver, not NVIDIA's
closed source "nvidia" driver (even though you installed the package
"nvidia-glx")!  You could conform this by running:
        glxinfo | grep direct
and see if the answer is "Yes".

To fix this run the following and choose "nvidia" when prompted "Select
the desired X server driver":
        sudo dpkg-reconfigure xserver-xorg
If you don't want to miss with the other options and you just want to
change the driver:  Edit the file "/etc/X11/xorg.conf" and search for
‘"nv"’ and change it to ‘"nvidia"’.

You need to restart GDM for the change to take effect.  Either reboot
your system (preferred solution), or log out of GNOME/KDE and run from a
console "sudo /etc/init.d/gdm restart".

See if that fixes your problem.  If not, just repost here again.
Ziyad.
