Using two mis-matched video cards for OpenGL.

[rubin427]

I have an onboard intel video card, and a pci-e nvidia card. Ideally, I'd like to be able to use both cards at the same time in a mode that provides hardware opengl acceleration (GLX, etc).

For the time being, I am less interested in the specifics about particular hardware. I am still trying to understand the big picture.

It seems to me, at very least this will involve two instances of the X-server, each with a custom xorg.conf file.

The issue I am trying to understand is dependencies and interactions between the video driver and opengl and glx libraries (.so). I know that when we install the proprietary nvidia driver, it also goes through the system and modifies opengl libraries so they are optimized for the nvidia card. I have to imagine this precludes the use of those same libraries on the other intel card.

My question here is, is it feasible to have the intel and nvidia card running opengl side by side, or would a hack like building one X11 install in a chroot environment be necessary to isolate incompatible versions of OpenGL libraries?

Thanks.
