xorg.conf multiple users compiz issue

OK, here's the deal. I figured out how to turn off the TV "Unknown" and it worked.
I tested it in an alternate user logon.
Thing was, I couldn't get compiz to work -- but compiz works on just on ONE login. Mostly, it was "Can't do that" or "checking for XGL not present" on the other login. Making multiple changes back and forth... nothing.

Well, the answer is stupid and *for me* has absolutely nothing to do with drivers, even though I have an "unsupported" Intel card. The answer was staring me in the face from a little other error message: "No GLXFBConfig for default depth". Why this login and not the other?

The answer: alternate switch-user logons have new display numbers (see /var/log/Xorg.#.log) and by default, you don't have an Xorg.20.conf. Sure, sure, xorg.conf is supposed to handle it for you, right? nah. I have to put this to the test, but in the mean time, additional Section "Screen"s are the likely fix in xorg.conf.
