This is a cumulation and culmination of several posts now.
I recently was successful installing the latest NVIDIA drivers (v1.0.9269), which support AIGLX.
The next thing that must be done is an edit of the X.org configuration file to enable AIGLX. I have already done this once before.
One final adjustment is necessary for using AIGLX with the NVIDIA drivers. The following line needs to be added to the X.org configuration file in the “Screen” section.
Option “AddARGBGLXVisuals” “true”
Once that change has been made, you should be able to start an ordinary session (now using AIGLX) and then start Beryl. If you need to install Beryl as well, you can see how I did it a while ago.
You may need to stop the XFCE window manager (xfwm4) first, using these commands.
killall xfwm4
beryl-manager &
Enjoy!
