So I have been trying to get my Lenovo y50-70 laptop, which has both the intel integrated GPU and a GTX860M, to run Linux Mint Rebecca 17.1.
I have installed the ppa repository

```
sudo add-apt-repository ppa:xorg-edgers/ppa

```

and the drivers

```
sudo apt-get install nvidia-343

```

as well as the bumlbee switch that supposedly I need as well.

```
sudo apt-get install bumblebee bumblebee-nvidia primus

```

I have tried a couple of other methods as well and always after these installs when I reboot Mint I get "Cinnamon just crashed. You are currently running in Fallback mode".

Does anyone know how to successfully install and run the nvidia drivers on a laptop that implement this graphics switch?

(Also I have followed the guide with the rebecca distro 17.1 notes that say I need to change the grub boot to add "nomodeset" but to no avail).

Any Help would be great!
