One more idea - check the permissions:
ls -l /var/run/bumblebee.socket

On my system it says:

srw-rw---- 1 root bumblebee 0 pa┼║ 23 08:27 /var/run/bumblebee.socket

what basically means that only the members of bumblebee group are able
to use this service (and the nvidia card).
If the "groups" command does not list "bumblebee", you need to add your
login name to this group; either by editing /etc/group or by the command

sudo usermod -aG bumblebee yourloginname

Then logout and login again to make this effective.
