Note: Even after I followed the explanation in another question (as my question was identified as a possible duplicate of it) nothing changed of what I am detailing below.
I know there are myriad questions and how-to's about installing and using NVIDIA graphics card on Ubuntu, but my case is a bit different (probably due to using Ubuntu 19.04).
My laptop has a GeForce GTX 1050 NVIDIA graphics card besides the "default" Intel graphics card. (I am using the laptop's own display and nothing is connected to the HDMI port.)
$ lspci -k | grep -A 2 -i "VGA"

I already have installed the latest recommended NVIDIA driver (probably several weeks ago!):

However, system Settings | Details | About displays that the following graphics processor is active:
Intel® UHD Graphics 630 (Coffeelake 3x8 GT2)
I get the following output from nvidia-smi command:
$ nvidia-smi

The GPU seems idle.
And the nvidia-settings command just displays a simple window like this:
Considering all these, I believe that currently the Intel graphics card, and not the NVIDIA graphics card is active in my system.
Purging and reinstalling the NVIDIA driver does not help.
Certainly I am missing something. But what?

Nvidia needs a working Xorg installation to operate within. As your current Xorg Gnome desktop is broken you can try the Unity Desktop to get nVidia drivers working first.
I have a GTX 970M but I know this driver also works with the GTX 1060M which is one step above yours:
If you need sound turned on for your nVidia HDMI and most manufacturers these days have it powered off, then you need to use this:
Here is someone that has taken the
prime-selectcode and patched it because it wouldn't switch fromnvidiatointel. If his patch doesn't help you perhaps he can?Your reported symptoms exactly match the case of having an installed Nvidia driver, but logging in with wayland. At the login screen, click on the little gear next to the signin button, and select a non-wayland choice. Proceed to login, and the nvidia-settings should be fully functional.
