Leave a comment

This worked perfectly on a Asus Zenbook Pro Ux501Jw running GTX 960M in secondary GPU mode (Optimus).

Steps:-

1. First step after installing Ubuntu is to install all updates. You may use the software updater or simply run: 

sudo apt-get update && sudo apt-get upgrade


2. Add the Xorg-edgers ppa using 

sudo apt-add-repository ppa:xorg-edgers/ppa
sudo apt-get update

Important Step => 

sudo apt-get upgrade && sudo apt-get dist-upgrade

3. Now Install bumblebee and Nvidia drivers using 

sudo apt-get install bumblebee bumblebee-nvidia primus nvidia-352

4. Add the current user to the bumblebee security group. 

sudo useradd -G bumblebee yourusername

For Ubuntu 15.04 only: you need to manually enable to bumblebee daemon using 

sudo systemctl enable bumblebeed`

5. This will take care of the Installing the required software on your system. We need to configure it.We start by enabling bbswitch and intel i915 Driver. 

sudo -H gedit /etc/modules

Ubuntu 15.04: the file is /etc/modules-load.d/modules.conf

Add these two lines to it 

i915
bbswitch

6. Edit the bumblebee configuration file. 

sudo -H gedit /etc/bumblebee/bumblebee.conf

1. line 22: 

Driver=nvidia

2. line 55: 

KernelDriver=nvidia-352

3. line 58: 

LibraryPath=/usr/lib/nvidia-352:/usr/lib32/nvidia-352

4. line 61: 

XorgModulePath=/usr/lib/nvidia-352/xorg,/usr/lib/xorg/modules

7. In addition to this there is another file that needs to edited. 

sudo -H gedit /etc/modprobe.d/bumblebee.conf

Add this line at the end. 

blacklist nvidia-352

Now you may reboot. After reboot, check using sudo apt-get install mesa-utils if mesa-utils is not already installed.
