Are you looking for Bumblebee for supporting your Optimus hardware on Linux? We've moved!
Because we have fully rewritten the Bumblebee concept in C, we decided to start in a new repository. The bash version from the 2.4.x series has been superseded by the C version which can be found on http://Bumblebee-Project.org/. This repository is kept for historical reasons. Please report issues on http://Bumblebee-Project/issues and not here!
