[Solved?] Optimus & libgl - Is this doable?

So my ultimate goal here is to be able to switch between graphics cards by switching sessions in the display manager (kind of like the Ubuntu implimentation of Optimus support).

Using scripts I can unload and switch off the NVIDIA card; however, when starting X with Intel I'm not able to load GLX (obiously, because nvidia-libgl and mesa-libgl can't coexist).

If those two libgl packages are just symbolic links (pretty sure they are), can't I just set the appropriate libraries with somthing like "export libgl_drivers_path" or even create the symlinks myself with the switch scripts?

Is there a better way to impliment libgl switching? Is this even possible without messing with code/packages? Should I give up?

(Not sure if this is the right section. I'm new to the forum, not Arch.)

OK, I've taken apart the nvidia-libgl and mesa-libgl packages, and started making a script to swap between the symbolic links. This should work, but it's kind of hacky. If anyone knows of a more elegent way to do this I'm all... eyes.

Re: [Solved?] Optimus & libgl - Is this doable?

OK, everything seems to be working. Just have to figure out how to make the Intel graphics stop tearing, and intigrate these scripts into a display manager - then the dream will be complete.

Thanks for the moral support, or somthing like that. Here's the ugly horrendous hack:

If you see something horrible (besides the obvious) and/or make changes... do share. Marking as solved I guess.
