I am using 64bit ubuntu 15.04 and in the hardwared; NVIDIA GeForce GT630 graphic card is attached. I have downloaded driver for this graphic card from the website given in the official website as shown in Fig.NVIDIA-GeForce GT630-website-screen shot, I have followed every method mentioned in different sites such as
- Type in,
sudo service lightdm stopand then
- to run as root
sudo service lightdm start
I have crashed my Linux 15.04 3 times in this way and now I am unable to even re-install it which is a separate story. Please, help.
