Really like it so far, they made it very easy to install with the newest release. Do I install the Linux x84 64 nvidia drivers for my gtx 1070? i am guessing yes, or does ubuntu do it automatically at install? how about the intel chipset? does it do that automatically? i have the i7-7820hk cpu and gtx 1070 gpu
All drivers are included in the kernel. The only driver needed is the Nvidia one, thanks to Nvidia not disclosing the information to have the free one working out of the box, like AMD and Intel does.
It's a bad practice to install the Nvidia driver from their page (the .run file) because you have a fixed driver version that doesn't update with newer kernel versions, and that could give you problems.
The way explained on the second link works fine, but it's no longer the 390 version, it's 410. If you are going to install from the terminal, type "sudo apt install nvidia" and then press the tab key twice so you get an autocompletion with the available options, use the latest one. Also, always check that the PPA you are adding is compatible with the version of Ubuntu you are using, the newest ones (18.10 for example) take some time to get added.
The easier way is to open "software & updates", go to additional hardware and select the Nvidia driver there, it's the "official" Ubuntu method.
Today I installed 18.10 on my notebook (thanks to having to donwgrade to a 32GB SSD). The new Gnome version with the performance patches and the new theme really help. Plus it seems I have a better wifi driver with it.
