Comment 2 for bug 1676102

I found a way to fix my issue. I ran the following commands to remove pre-existing nvidia drivers and downloaded and installed the drivers from your repository. After rebooting, Xsession became visible. Finally a success.

Press Ctrl+Alt+F1 to go into tty1.
Login to tty1.
sudo apt-get purge nvidia-*
sudo add-apt-repository ppa:graphics-drivers/ppa -y
sudo apt-get update
sudo apt-get install nvidia-375 -y
