This driver supports GLX_EXT_texture_from_pixmap and therefore AIGLX and Compiz should work now.
Another amazing feature is “the new “Display Configuration” page for nvidia-settings. NVIDIA’s new display configuration options are similar to ATI’s dynamic display management options. TwinView can now be enabled real-time without restarting X (Xinerama requires X restart). TV-out on NVIDIA cards can also be enabled real-time. The screenshots below demonstrate these display options”.
