How to find video display name for xrandr

I’ve just installed Zorin 16. The video display is wrong. In “settings”, my display name is shown as “Unknown display.” The resolution is set to 1024x768. I have generated the modeline the “1920x1080 60,” but I can’t add it with xrandr because I can’t find the name of my display. This is a deal breaker. I am not willing to install the proprietary Nvideo drivers. I’ve used the generic x-windows driver on half a dozen other didtros, and on one of them had to manually set the resolution, but can’t remember how I got the display name. I don’t get it. The Live CD configured the display fine. What did it do wrong during the installation?


sudo ubuntu-drivers autoinstall

To install the Nouveau drivers you need, then try setting your resolution.
If that does not work, you can try the x-swat repo:

sudo add-apt-repository ppa:ubuntu-x-swat/updates

sudo apt update && sudo apt full-upgrade

Then test resolution settings.
