My experience has been that Nvidia 304.x will not work on Ubuntu 18-based systems, such as LL 4.x. that's because of the kernel being upgraded. AFAIK, kernel 4.4 is the last that supports that driver.
now the OP suggest that he did succeed in doing this. I have heard from the Ubuntu forum that it may be possible. I would love it as I could then also update from LL 3.8. however at least on my system I am doubtful.
LL 3.8 will work with 304, and is supported until April 2021. Another system that will work, and is still supported, is Ubuntu 16.04. You can also get extended security support for that, good till 2024. and kernel 4.4 is supported at least to 2024 as well.
