I use Ubuntu or Ubuntu Gnome 14.xx on NVIDIA GTX 750 TI. It requires the specific driver for booting. Even NVIDIA supports the driver on it's official website, sometimes installing it is not really stable specifically after you do update patches related to video drivers from Ubuntu archives.
After several trials, I realized that using ppa:xorg-edgers
is the best way to install and maintain the driver so far. It does not require you several additional steps but you just do the following.
You need to do the way in this link because you need to set nouveau.modeset=0
for the kernel option. You don't need to do it everytime or add it into somewhere such as init code.
Open terminal on your desktop with Ctrl+Alt+T
or click terminal icon then do the following.
sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-get install nvidia-343
And reboot your system. That's it. You would better read this article to know what is this.
