Ubuntu / Mint: Install latest Nvidia drivers

Constantly having trouble with the Nvidia drivers install.
Quick howto:
If there is already any NVdiai driver installed, then run :
telinit 1 #to go to single user mode sudo /usr/bin/nvidia-installer --latest
If to be installed freshly:
sudo su - cd /root wget ftp://download.nvidia.com/XFree86/Linux-x86_64/latest.txt cat latest
This tells you the latest version then you can
wget ftp://download.nvidia.com/XFree86/Linux-x86_64/304.43/NVIDIA-Linux-x86_64-304.43.run
I have no idea why
wget ftp://download.nvidia.com/XFree86/Linux-x86_64/`cat latest.txt| awk '{print $2}'`
doesnt work, I will need to look into this deeper.
Then:
telinit 1 cd /root apt-get remove nouveau* ./NVIDIA-Linux-x86_64-304.43.run
Reboot afterwards
