Attempting to use Wayland results in monitor and other problems

[goodstuff9]

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?

It says they are recognized and are using the NVidia driver.

What does your /var/log/xorg.0.log say?

Sorry, I don't know how to interpret all the stuff in that file, so I present it here as a file attachment (*.tar format) hoping you can make some sense out of it.

Your NVIDIA GeForce GTX 1650 (TU106-A) at PCI:1:0:0, ID'ed as GPU-0
It is using NVidia driver 550
It has:
DFP-0 connected to an HP Inc. HP 27 QD
DFP-1 connected to a BBY NS24D310CA21
DFP-2 connected to a UPG DP2VGA

Your NVidia GeForce RTX 3050 (GA107-A) at PCI:6:0:0, ID'ed as GPU-1
It is using NVidia Driver 550
It has
DFP-1 connected to an Acer S271HL display
DFP-3 connected to an Acer KA242Y

Those "are" the five displays you said you had connected. But the it gets weird with the RTX 3050.

On that card, a ghost port ID'ed as "none-3-1" does not say if it is connected or not, nor did it find any EDID, BUT on a probe of that port, determied a modeline of

Modeline "1920x1080"x60.0  124.42  1920 1920 1920 1920  1080 1080 1080 1080 (64.8 kHz eP)

So (somehow) kept setting up that invalid port.

It did not ID that ghost port as a valid port name, nor could it recognize things there in a manner that makes sense.

I would post that file on the NVidia forum. Seems to me that it is either a problem with the card, or the driver...

^^^ You could rule out a problem with the driver if you uninstalled 550, and installed 540, to see if it has the same error.

Agreed with opting out of driver 550, this is unusal:

[  5461.085] (II) NVIDIA(GPU-1): Renaming GPU-1 to GPU-0
[  5461.085] (II) NVIDIA(GPU-0): Deleting GPU-0

With my driver current

 NVIDIA-SMI 550.67                 Driver Version: 550.67         CUDA Version: 12.4

and GPU "NVIDIA GeForce RTX 3050 Ti Mobile" I run more than 2 Displays and I get a lot of tearing and on wayland just a tiny bit better.

And older driver is my second as MAFoElffen suggests.

Thanks again for helping. A couple followup questions:

1) Your last post focused on the ghost port/monitor problem. Do you think that is related to the other problems I listed in my original post?

2) My main concern is why Wayland will not work with these graphics cards and drivers. I am not married to these particular graphics cards, I'm close to someone who purchases things like used graphics cards, so if I were to replace them, I'd be reimbursed. My main goal is to be able to have these five monitors working without problems under wayland. (I am not into gaming.) So, before I spend a lot of time in an Nvidia rabbit hole, do you know, are there alternative graphics cards I could get that would likely work for what I wish to achieve? Because then in that case I'd rather just install those alternative graphics cards and related drivers and happily carry on, and just unload the Nvidia stuff.

3) Where do I find that "Nvidia forum" you're referring to???? When I look at all the forums within "Ubuntu Forums", I don't see anything with that title? What am I missing?
