The 6106 driver, for x86 and x86-64, includes the nvidia-settings
gui configuration utility. Just run `nvidia-settings` once you
have the driver installed and have X running.
A brief user guide is available here:
nvidia-settings uses the NV-CONTROL X extension to communicate with
the X server. nvidia-settings is GPL.
Details on the NV-CONTROL X extension, as well as source code to
nvidia-settings is available here:
Feedback is very welcome.
