Ok,
I've installed ubuntu 16.04 on my 2015 Imac (Geforce 700 series). Installation was a succes on first sight. Anything works.
So I proceed to go further with my project to install some Machine Learning software. Ofcourse I need my Nvidia Geforce 700 series to work for computing everything. So by default it installed the Nvidia x server 'driver'.
Next step was to install the proper nvidia drivers, cuda & cuddn. But to do that I need to access the tty console. And that just gives me a black screen. I've already follow three different SE answers with no result. This one for the driver = here
Whereas sudo service lightdm stop
stops my imac from working, until I reboot (bla(n)k screen)
Also tried changing the grub file = here
I've tried it all in this question, no results. Other than when booting into ubuntu it doesn't recognize video mode. But afterwards It shows me a big Nvidia logo.
So how do I get this tty terminal to work on a 2015 Imac/Ubuntu installation (refind)
following to list my tty gives me this:
ps aux | grep tty

Thanks ahead.
