Mouse cursor goes off screen - Kubuntu 20.04, tried to change xorg.conf nothing changed, how can I fix this?

Question

X.Org

Good afternoon, I recently encountered such a problem as moving the mouse beyond the right edge of the screen, which did not really interfere until I decided to play the "stasis" toy and it turned out that part of the interface just went to the right in it. After rummaging through the Internet, I came to the conclusion that the trouble lies in several monitors, or rather the system thinks so, I have one monitor on my laptop, mesa firewood. They advised to look at xorg.config along the path etc/x11/xorg.config. The file was not there, according to this

instructions:

created from the logs, it turned out how I realized that I already have 16 monitors displayed. I removed all mention of them, except for one, but alas, it did not help.
