In Bumblebee 2.4, VGL_READBACK=pbo was set in the configuration and may improve performance by 2 times.

For the Ubuntu 3.0-1~...ppa4 package, I've applied a patch to set this in optirun.c. Should this be applied in this way to the Bumblebee source too? Or should we make it a bumblebee.conf option? It can always be overridden by setting VGL_READBACK manually.

I agree on making it a configurable option in bumblebee.conf under [optirun]
Should be set to a safe default in the code

This has been set as default in develop.
