Autoswitch to optirun

[datacompboy]

Hello!

what about automatic switch of programs, using some of LD_PRELOAD ways?
If we inject .so library, that will analyze calls, and if it detect access to 3D -- automatically runs optimus & replace ENV variables to use secondary video card?

That will allows automatic switch by heuristics, with allowance to override using ~/.bumblebee, /etc/bumblebee.conf in somethinkg like:
[/usr/bin/glxgears]
force=intel

[/usr/bin/glxspheres]
force=nvidia

This would be a very nice thing to have and also take some efforts to implement. Maybe someone with a background on OpenGL programming can do something here?

Any updates?

A proof-of-concept was implemented in October 2012 as https://github.com/amonakov/libgl-switcheroo, but even back then the interest was minimal (understandably, I guess: explicit per-run control via optirun would satisfy most practical needs, and of course the approach used there, LD_LIBRARY_PATH pointing to a FUSE tree, is far from ideal).
