Most probably the "bumblebee daemon" service is not running, as it says.
Strange, as it should be started after the install of the bumblebee
package, which in turn should be pulled in by the install of
What you may try:
sudo service bumblebeed start
sudo initctl start bumblebeed
If it complains that there is no such service, then the package may be
sudo apt-get install bumblebee
Actually, the bumblebee daemon is started by upstart via
/etc/init/bumblebeed.conf so there are no links to
/etc/init.d/bumblebeed script from any /etc/rc?.d directories. If you
disabled upstart somehow, then you would need:
update-rc.d bumblebeed defaults
to make the demon start after boot.
If this will not help then I am at a loss; but which version of nvidia
drivers have you installed? I remember that I was unsuccessfull with
upgrade, but bumblebee with nvidia-304 works for me on ubuntu 14.04
