That's then the unsupported use case. Maybe it's not a problem, because 
actually Nvidia's driver doesn't use glamor, so libGL is just loaded 
into the X server doing nothing.

Maybe the problem is the other way around. You have integrated Intel 
graphics and an Nvidia card: Multi Head, Optimus, whatever. If you now 
enable glamor acceleration in the Intel driver (they invented glamor 
after all, but it's optional and not the default there) it will use 
Nvidia's libGL for 2D via glamor -- which I'm sure will fail horribly.

Maybe one should ask Nvidia for clarification here. Or just wait and see. :)
