Снес nvidia* bumblebee* bbswitch* + убил репозиторий x-swat.
Поставил все заново:
sudo apt-get install nvidia-331 (nvidia-settings не было в стандартном репозитории "выругался", но при установке в консоли было видно, что он его установил как зависимость)
sudo apt-get install bumblebee bumblebee-nvidia primus virtualgl
После установки в bumblebee.conf изменил nvidia-current на nvidia-331
в результате получилось:
KernelDriver=nvidia
LibraryPath=/usr/lib/nvidia-331:/usr/lib32/nvidia-331
XorgModulePath=/usr/lib/nvidia-331/xorg,/usr/lib/xorg/modules

# If the X server does not automatically detect your VGA device,
# you can manually set it here.
# To get the BusID prop, run `lspci | egrep 'VGA|3D'` and input the data
# as you see in the commented example.
# This Setting may be needed in some platforms with more than one
# nvidia card, which may confuse the proprietary driver (e.g.,
# trying to take ownership of the wrong device). Also needed on Ubuntu 13.04.

# Setting ProbeAllGpus to false prevents the new proprietary driver
# instance spawned to try to control the integrated graphics card,
# which is already being managed outside bumblebee.
# This option doesn't hurt and it is required on platforms running
# more than one nvidia graphics card with the proprietary driver.
# (E.g. Macbook Pro pre-2010 with nVidia 9400M + 9600M GT).
# If this option is not set, the new Xorg may blacken the screen and
# render it unusable (unless you have some way to run killall Xorg).
