I am new to Ubuntu and Linux, but am not new to installing other operating systems and software. I have been attempting to install Ubuntu 16.04 from DVD on a machine with the following hardware:
- ASRock Z170 OC Formula motherboard, with BIOS version P7.40
- Intel Celeron G3900 at 2.8 GHz (NOT overclocked)
- 8 GB DDR4-2133 SDRAM
- TWO nVidia GTX-1070 video cards
- Samsung 850 Pro SSD 512 GB
- Samsung Syncmaster 305T Monitor
Onboard Video and Secure Boot are disabled in BIOS.
When booting from the CD, and when booting the installed Ubuntu, I had to edit the linux command line in Grub to add nomodeset to avoid getting a black screen after the Grub display. The nVidia driver was NOT yet installed initially.
My application requires installation of the native nVidia display drivers. Therefore, I tried installing the nVidia drivers (version 384) through Ubuntu's Additional Drivers application. The installation appeared to proceed normally as far as I could tell. However, upon rebooting, the screen now briefly changes to the Ubuntu login screen background color, then my monitor loses the video signal, and the actual login screen is never displayed.
However, I am able to toggle into terminal mode by using CTRL ALT F1. I then attempted to resolve the above problem by trying various solutions listed at the following links:
The most commonly recommended solution in these threads seems to require running the following commands from a terminal session:
sudo apt-get purge nvidia-* sudo add-apt-repository ppa:graphics-drivers/ppa sudo apt update sudo apt-get install nvidia-384 sudo reboot
However, following that procedure has not changed my results. I suspect that I am missing some other important step, but can't figure out what it is. Can someone help?
