This question already has an answer here:

I have recently installed Ubuntu 16.04 on my Dell Inspiron 15 7559.


  • Intel® Core™ i7-6700HQ CPU @ 2.60GHz × 8
  • 1TB drive
  • 16GB memory
  • NVidia Geforce GTX 960M

Everything works apart from my nvidia card. I have tried installing many versions which all led to low graphics mode error. I recently tried the v384 driver and my system booted up normally and I thought I'd succeeded, but I was wrong. My Additional Drivers page shows that I have nvidia 384 selected but nvidia x server is empty and system info still shows that I'm running Intel Skylake.

How can I fix this?

I have finally found the answer on my own.

For those that are experiencing the same issues, you have to install bumblebee for optimus support. I used the instructions in this YouTube video, and it worked for me.

sudo apt-add-repository ppa:graphics-drivers
sudo apt-add-repository bumblebee/testing
sudo apt-add-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install nvidia-367 # or install the newest version if there is a newer one
sudo bumblebee-nvidia bbswitch-dkms prime-indicator
sudo prime-select intel
sudo reboot
