Bug Description
Binary package hint: xorg
Description of the problem:
By default composite is enabled in xorg. However unless it is disabled or an extra option added, GL applications will be unable to run when using the binary nvidia-glx-legacy drivers.
Steps to reproduce:
1. Install Feisty (Herd 5).
2. Install
nvidia-glx-legacy
on a GeForce 1.
3. Restart gdm .
4. Run
glxgears
.
Expected result:
Spinning gears to be displayed.
Actual result:
Xlib: extension "GLX" missing on display ":0.0".
Error: couldn't get an RGB, Double-buffered visual
Additional information:
The following is reported in /var/log/Xorg.0.log :
(EE) GLX is not supported with the Composite extension
This can be worked around by adding either of the following to /etc/X11/xorg.conf :
Section "Extensions"
Option "Composite" "Disable"
EndSection
or (Under Section "Device")
Option "AllowGLXWithCo
With regard to the later option the README has this to say:
[AllowGLXWithCo
(this option has often worked for me but I don't do too much GL stuff)
This problem has also been documented over in the wiki:

Version information:
xorg 7.2-0ubuntu6

Not dissimilar to Bug #90688 which was for fglrx . Behaviour might be different for the other two NVIDIA drivers.
