I have an Acer ET322QK monitor. It works with Windows 10, Ubuntu 18.04 and Linux4Tegra. However, when connecting my computer with newly installed Ubuntu 20.04, it cannot seem to use the monitor properly. In "joined" mode it is black. If I mirror it, it will show the desktop on one fourth of the monitor but I am not able to control anything with the mouse. When I tried to use it as the only display it put me in some kind of state where I had to restart the computer by pressing the power button to gain control again.
It should be noted that the settings recognizes the display just fine. It lists it as "Acer Technology 32 inch" and the list of resolutions I can choose from looks right.
I see that there are many posts about monitors not working and usually it is resolved by updating a driver or something. However, I am not good with these things. Could someone advise me what I should do in my situation? If it is a driver I need, how do I know which one?
As for the additional drivers in the settings:
The default was "Using X.Org X server" and that is the one that seems to work best. The one selected in the image didn't seem to recognize the monitor, as it wouldn't show up the displays menu.
Running dpkg -l *nvidia* in the terminal yields this:
