Problems after upgrading to 14.04 Show Only Black Screen

After upgrading to 14.04 few people face issue of really low graphics.

Need to do few steps :

On Black Screen,
Press ALT + CTRL + F1

sudo apt-get install –reinstall ubuntu-desktop
sudo apt-get install unity
sudo apt-get purge nvidia* bumblebee*
sudo apt-get install nvidia-prime
sudo shutdown -r now

 

After restart, it will be fine 🙂
