Nvidia 304 driver install in 18.04

Try to install v304 driver on Ubuntu and it will fail due to xorg version
try to downgrade to older version of xorg and will be more dependencies from that need attention

If really need to keep old GPU running, consider switching to Debian that still has this driver available

I have been happy using a GT730 for a while
Get a later card version with Kepler core GPU and can use latest v396 driver
