I was working on my stuff, the screen blocked itself due to inactivity and when I logged in again, only the screen on the left is active.
I’m using XFCE as DE and it is not detected from its display settings.
In Nvidia X Server Settings there is an entry for the screen in the menu but I cannot enable it for some reason.
Here I attach the bug report: nvidia-bug-report.log.gz (435.6 KB)
Thank you for your help :)
