I've been trying to install bumblebee but I have been unable to get it to install properly. I have added the proper repos to dom0 by copying the rpms over to it and installing them. But then I get a "Failed to synchronize cache for repo 'bumblebee', disabling" error when attempting to update dom0 or install bumblebee. How did you get it to work?
