[clug] Nvidia Optimus non-support for Linux

[George at Clug]

    For anyone interested in Nvidia Optimus in Linux, I did get as far
a the below output suggests. Not being knowledgeable in this area, it
is my best attempt. I can say that many solutions suggested on the
internet did not work for me. And I could only get "xrandr
--listproviders" to list one provider. I also did not want to hack my
Linux installation all that much, I was willing to do a few config
changes but things like recompiling the kernel, etc, were beyond where
I wanted to go.

xrandr --listproviders
