Installing nvdia driver on linux
Downolad nvidia driver from nvdia website stop xserver to do this restart with init 3 or edit /etc/inittab file to change runlevel to 3 then restart if nouveau driver is used nvida will detect (we can manually disable this refer nvidia readme) this at installation and add an entry in /etc/modprobe.d/nvidia-installer-disable-nouveau.conf the entries in the file will be blacklist nouveau options nouveau modeset=0 this will disable nouveau but if os is taking this at boot level this wont be enough to disable, to disable this at boot level we have to edit boot configuration file to add an entry there or at the time of booting press e and go to kernel line and add this at the end rdblacklist=nouveau this will disable nouveau at boot level also go to /etc/Xorg and take a back up of xorg.conf file (incase if installation fails we can just restore and bring back the system to old condition) now go to the folder where nvdia driver is stored and run sh nvdia installer
