I use ubuntu 17.10 and It works fine. In my case I think drivers came preinstalled. All I had to do was enable nvidia propiertary drivers on "additional controllers".
Let me know if that works for you. Maybe you need to install them.
Funny part is with another Rig was working fine with a 1060 3Gb with this second one 1060 6Gb give me hard time, I am upgrading the Mobo bios to make sure nothing is missing... Mobo is a Asus 970 pro gaming,aura ...I know it's old but I don't like waist
just for the news I try already the 387.34 and all the versions before like 384.90, 384.98 but nothing give me a log in access and I am getting in and bounc me back at the log in, then I have to Ctrl+alt+F1 and apt purge nvidia* and restart with xserver drivers
feeling hopeless ... I dig all possible online resources no solutions for now... maybe I should just try different Mobo... if so would sucks
thx
