Установил bumblebee на Fedora 20 x64 с официальной Wiki-страницы. Установка прошла успешно, правда выдает вот такое вот:
[evgen@localhost ~]$ optirun firefox [ 1620.840459] [ERROR]The Bumblebee daemon has not been started yet or the socket path /var/run/bumblebee.socket was incorrect. [ 1620.840656] [ERROR]Could not connect to bumblebee daemon - is it running?
