I installed Ubuntu 22.04 LTS on an Acer Nitro 5 AN515-55 with Nvidia Geoforce GTX which worked fine for about 3 months. Yesterday I shut it off; when I powered up again, the second monitor is not recognized. Tried several ideas with no luck, so finally reinstalled the whole thing... After a few tries, I finally got the second display to be recognized by using the X.org driver.
Now when I try to move the display side in settings-Displays, after clicking on Apply, my laptop goes to the start login screen and nothing is changed. I tried to run sudo ubuntu-drivers autoinstall
and see:

I installed from the same live USB stick I did originally AND updated the system a couple times (With Software updater and with console). Acer's support have not been helpful.
