Xorg Ryzen with bundled AMD + Nvidia RTX 2060 (mobile) HDMI interface not detected

Graphics / Linux Linux
1

I bought a new laptop a few days ago (Asus TUF with RTX 2060), performed a clean install of Kubuntu 18.04 and after having connected a second screen via HDMI, nothing happened.

I have a dual boot with grub (with Win10) and everything works fine on Windows.

I performed multiple steps trying to make this work, e.g. Secondary monitor via HDMI.

When running without any nvidia drivers installed, second screen was recognized but there were only some colorful pixels rendered there and I couldn’t use it anyway.

I tried installing the newest nvidia driver 440.64, tried installing some previous releases as well (440.44, 440.46).

When I installed the newest driver (440.64) having connected my HDMI cable, my second screen finally worked, but then I couldn’t use my laptop’s base screen (was not discovered, xrandr displayed no other interface than HDMI). Then I couldn’t revert my config to make my basic screen work (even tried purging all nvidia packages). After rebooting with disconnected HDMI cable, I just couldn’t render graphical interface and only text was available.
Reinstalled OS to make my basic screen work again.

I tried using lightdm, tried switching to gddm3.

After a few OS reinstalls (multiple versions - 18.04, 19.10, 20.04 multiple times) and some different Xorg config solutions, I gave up after 3 days and decided to ask for help over here.

Currently, I have Kubuntu 20.04 installed with recommended drivers (440.59).

Snippets below present some common data / configs and here’s the link to nvidia-bug-report.log.gz.

Here are also my /usr/share/X11/xorg.conf.d/ configs - xorg.conf.d.tar.gz.

I’m a pretty new Linux user and there are many things, I can’t figure out myself yet.

A little update.

All I did today was apt-get update, apt-get upgrade and xrandr recognizes HDMI output now.

I can’t yet use my monitor, though.
When I want to extend the screen, all I can see on the second screen is the cursor. When I move any window to the second screen, it just isn’t displayed there. If I aim the window borders, though, cursor changes and I can change the window size or move the window on the second screen. It just isn’t displayed and all I can see is the black screen with cursor.

So, I played around with xorg.conf.
I used nvidia-xsetting to create basic xorg.conf, which enabled HDMI, but completely disabled my laptop basic screen.
After having modified the file a little, my both screens finally work!

That’s how my /etc/X11/xorg.conf looks like:

Is there a solution for Wayland instead of X.org?

The better way to do this on xorg and ubuntu would be:
https://forums.developer.nvidia.com/t/nvidia-xconfig-doesnt-do-what-i-want-it-to-nor-does-nvidia-settings/107883/7?u=generix
Regarding wayland, this would be up to the compositor used, nothing configurable.
