Comment 11 for bug 1268217

You can have both bumblebee and nvidia-prime installed. Even nouveau + PRIME would work, it just requires appriopriate configuration. This could be useful for experimenting or if you want to use bumblebeed/bbswitch to save power and to use nvidia-prime at other times (requires restarting X though).

Detecting whether bumblebee is enabled or not probably requires checking for checking whether `/etc/init/bumblebeed.conf.override` contains `manual`. Upon installation the daemon is always started, but it might fail to start in some cases (when the graphics card is hidden via BIOS settings for example).
