Have you checked to see if you are loading the glx module?  Never used ubuntu, 
but every distro I have used with nvidia drivers has required me to edit 
the /etc/X11/xorg.conf to not load the dri module and load the glx module.

Example from /etc/X11/xorg.conf on this box:

Section "Module"
        Load  "ddc"  # ddc probing of monitor
	Load  "dbe"
#	Load  "dri"
	Load  "extmod"
	Load  "glx"
        Load  "bitmap" # bitmap-fonts
	Load  "type1"
	Load  "freetype"
	Load  "record"
EndSection

$ glxinfo
name of display: :0.0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4
<cut a bunch more output>
