In Xinerama, any type of GLX rendering will not work on screens other
than zero in any implementation. If you have all NVIDIA cards, it
will work on screen zero only. I don't know if DRI will work on screen
zero.
In NVIDIA's "TwinView" capable dual head cards we support a Xinerama-like
mode that is not strictly Xinerama. OpenGL works on both heads in
that case. I don't know if the DRI based solutions have such a mode
(that is, a single logic screen that's not implemented with Xinerama).
