Ubuntu 22.04, gnome-shell 42.05.
Three monitors are attached to an Nvidia TU106 GeForce GTX 1650 graphics card, and two monitors are attached to a GA107 GeForce RTX 3050 (6 GB) graphics card. I'm having very strange problems with this, this stuff is beyond my understanding,
Under the "Supported Products" tab on this web site, https://www.nvidia.com/Download/driv.../223426/en-us/ , it says that the two graphics cards I have installed should work with Nvidia's 550.67 driver.
This web site, https://9to5linux.com/nvidia-550-67-...-wayland-fixes , indicates that the 550.67 driver should work with Wayland.
Here are the problems/issues I'm having:
A) When I boot into "Ubuntu" using X11, everything seems to work. But, when I boot using "Ubuntu Wayland", only the three monitors attached to the GTX 1650 graphics card work, the two monitors attached to the RTX 3050 graphics card are black.
B) Both xrandr and ARANDR report a phantom monitor: In ARANDR it is identified as "None-3-1", and in xrandr "None-3-1" is shown as connected. (This is in addition to the five monitors.)
C) As you can see in the screenshot below all my questions of Ubuntu's "Software & Updates" window, under the "Additional Drivers" tab, the RTX 3050 graphics card is shown to be using the most current 550 series driver - but that graphics card is not properly identified, instead for some strange reason it is listed as "Unknown". The GTX 1650 graphics card is correctly identified, but the 550 series driver is not even listed as an option. And as you can see, all drivers for the GTX 1650 graphics card are greyed out, so I can't select any of them for this graphics card. The only driver that can be used with this graphics card on that tab is something called "Continue using a manually installed driver."
My questions:
1) Why is the RTX 3050 card not properly identified on the "Additional Drivers" tab, and how do I fix that?
2) What is the mystery "manually installed driver" on the "Additional Drivers" tab for the GTX 1650 graphics card? Who installed that driver, and how?
3) Why are all the other drivers for the GTX 1650 graphics card greyed out? How do I enable them to be selected?
4) Why is the 550 series driver not even listed on the "Additional Drivers" tab for the GTX 1650 graphics card? How do I get it to be available for that graphics card as well?
5) Why do I have this phantom monitor of "None-3-1", and how do I get rid of it?
6) How do I get all five monitors attached to these two graphics card to work under Wayland?
