lost ability to detect second monitor

Question

I know there are plenty of threads on this topic, but apparently you need 50 rep to comment. I have, however, tried all the things in those threads.

Running Ubuntu 18.04 with nvidia-driver-430*. The asterisk is that when I tried downgrading to nvidia-driver-390 my additional drivers tab now shows "continue using manually installed driver" and the options for 390 and nouveau are greyed out. So I'm probably using 390?

Anyway, the problem is the same regardless if I use nouveau or any of the nvidia drivers. The second monitor is just not detected. It was working but when I tried to fix a completely different problem, tearing in videos, it stopped detecting it after I set my prime profile to intel. Switching back to nvidia didn't fix it.

I'm currently running: i7 8750H, RTX 2070, 1080p 144hz built in display, some benq 1440p 60hz external connected via hdmi

When I reboot to Windows, the monitor works fine. So it's not a problem with the wire nor the monitor.

Update: output of nvidia-smi :

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. 
Make sure that the latest NVIDIA driver is installed and running.

Update:

Switched back to 430, output of nvidia-smi :

I formatted your text by highlighting and clicking the {} button at top of question edit window. Now can you include the output of xrandr? — WinEunuuchs2Unix, Aug 12 '19 at 10:39
I suspect I've been abandoned...or, given the time of year, he may have gone on vaca... — gord0, Aug 19 '19 at 19:35
I wish I had a real vacation! No I ran out of ideas back then but now try dmesg | grep -i nvidia Also note I run version 384 in Ubuntu 16.04, 18.04 and 19.04 and never had a problem. So it's harder for me (versus someone who has had problems) to help you debug. — WinEunuuchs2Unix, Aug 19 '19 at 22:35
I misread your previous post not seeing you asked me to try something. I'll do that when I'm sober. Probably tomorrow after work. — gord0, Aug 20 '19 at 00:27
Ah. "...but I'm not a computer.". I'll try that when I get a chance, if it's the wrong syntax I'll wait for you. — gord0, Aug 20 '19 at 22:23
not on a computer lol. I was typing on my tiny phone without reading glasses. I'm home now with 17" laptop, 43" TV and 50" TV so I'm good to go. I want to dig up lots of stuff and post it in an answer below. — WinEunuuchs2Unix, Aug 20 '19 at 22:35
Unfortunately most times we've conversed I've been on my phone at work on breaks. At home I've been busy writing new software that checks retailer websites daily for price changes on big ticket items I want to buy on sale. I've finally posted an answer to help track down information you need to know to solve the problem. It's a WIP answer and I'll add to it as we go along. — WinEunuuchs2Unix, Aug 20 '19 at 22:58

Work In Progress Answer

Some items have been dealt with in comments and I'll roll them up into this answer later. This answer is destined to become a "How to I setup nVidia from A to Z" solution.

Xorg.0.log

This file is usually located in /var/log/ if not use: locate Xorg.0.log to find it.

After finding the file list it's contents which normally should look like this:

Prime Select

Type this to ensure nVidia is turned on for Optimus Laptops:

$ prime-select query
nvidia

If the answer is "intel" type sudo prime-select nvidia and reboot.

Ubuntu drivers

Type this to see what drivers are used:

$ ubuntu-drivers list
nvidia-384

To help others support you type:

$ ubuntu-drivers devices

== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==
modalias : pci:v000010DEd000013D8sv00001028sd00000708bc03sc02i00
model    : GM204M [GeForce GTX 970M]
vendor   : NVIDIA Corporation
driver   : nvidia-384 - distro non-free recommended
driver   : xserver-xorg-video-nouveau - distro free builtin

Check running drivers

See what drivers are running in memory with:

lsmod | grep nvidia
lsmod | grep nouveau

One or the other should return results, not both.

Check your hardware

Optimus Laptops should have two hardware devices:

$ lspci -nn |grep -E "VGA|Display|3D" 
00:02.0 VGA compatible controller [0300]: Intel Corporation HD Graphics 530 [8086:191b] (rev 06)
01:00.0 3D controller [0302]: NVIDIA Corporation GM204M [GeForce GTX 970M] [10de:13d8] (rev a1)

Check Xrandr

Xrandr should show both screens once they are plugged in:

$ xrandr | grep " connected"
HDMI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 1107mm x 623mm
eDP-1-1 connected primary 1920x1080+3840+2160 (normal left inverted right x axis y axis) 382mm x 215mm
DP-1-1 connected 3840x2160+1920+0 (normal left inverted right x axis y axis) 1600mm x 900mm

Note some newer laptops only support the HDMI jack through the nVidia GPU. They are hardwired unlike old days when the HDMI jack could be switchable between nVidia discrete GPU and Intel Integrated GPU.

Also note some newer laptops power off HDMI sound channel on boot to save electricity and only Windows was smart enough to turn on sound until Kernel 5.3 or something like that. If an older kernel you need nvhda.ko driver and newer laptop with no HDMI sound you need.

Grub modeset and blacklisting

Check dmesg (device messages):

[    1.406480] nvidia: loading out-of-tree module taints kernel.
[    1.406496] nvidia: module license 'NVIDIA' taints kernel.

Notice the last line? In question update yours appear missing.

When nouveau appears above or in Xorg.0.log or stop it from loading in grub with:

$ sudo -H gedit /etc/default/grub
# Find this line and add nomodeset
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nouveau.nomodeset=0"
# Your CMDLINE may have extra or fewer entries
# Save file, Exit editor and type command below
$ sudo update-grub
$ reboot

Don't type the lines with # above they are your instructions. Type what appears after the $ in the terminal.

nVidia or Nouveau can be blacklisted somewhere. I'll use my custom command but your command is:

locate blacklist | grep -Ev '/src|/usr|/lib'

For my custom command notice the dates will help you target which files to check:

$ llocate blacklist | grep -Ev '/src|/mnt|Sdk|/usr|/lib'
