Hi,

Are you still using Ubuntu? (I noticed Dapper Drake in your email.)

Ubuntu allows for having the libraries installed side-by-side and then use
the alternatives
system to set the OpenGL at your choice. Bumblebee sets the default driver
to Mesa
(necessary for the Intel GPU) and sets the ModulePath to the one containing
the nvidia
drivers.

For the Bumblebee project, see
https://github.com/Bumblebee-Project/Bumblebee.
