Which NVidia proprietary driver for GT 745M (Ubuntu 14.04 - Toshiba laptop)

Solution 1:

Generally it is recommended to use the NVIDIA drivers from the official Ubuntu repositories.
When there are problems with these drivers, you can install the latest official NVIDIA drivers.

NVIDIA released the final long-lived branch drivers version 361 this month.
The drivers 361.28 already are available in the Proprietary GPU drivers PPA.

Step 1 : Uninstall the currently installed NVIDIA drivers.

Highlight the Ubuntu entry in the GRUB boot menu.
Press the E key.
Add nouveau.modeset=0 to the end of the linux line.
Press F10 to boot.

On the login screen press Ctrl+Alt+F1.
Enter user name and password ... execute :

sudo apt-get purge nvidia*  
sudo reboot  

Step 2 : Install the latest official stable NVIDIA drivers.

Highlight the Ubuntu entry in the GRUB boot menu.
Press the E key.
Add nouveau.modeset=0 to the end of the linux line.
Press F10 to boot.

On the login screen press Ctrl+Alt+F1.
Enter user name and password ... execute :

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-361 nvidia-prime
sudo reboot  

Personal experience note and opinion :

I installed these drivers when they were released and they are working great without any issue.

Update addressing the question on how to revert back to the drivers from Ubuntu repositories :

Step 1 : Uninstall the currently installed NVIDIA software.

Execute these commands :

sudo apt-get install ppa-purge  
sudo ppa-purge ppa:graphics-drivers/ppa  
sudo apt-get purge nvidia-361 nvidia-opencl-icd-361 libcuda1-361 libxnvctrl0 libvdpau1 nvidia-prime nvidia-settings  
sudo reboot  

Step 2 : Install the NVIDIA drivers from Ubuntu repositories.

Execute these commands :

sudo apt-get update  
sudo apt-get install nvidia-352 nvidia-prime  
sudo reboot
