Ubuntu mouse sticking to the left edge, how to fix it?

Question

ubuntu

I installed ubuntu, maybe of course I put some kind of tick on the wrong one. The mouse sticks to the left edge, where the page scrolled. I think this is in order not to take the cursor out of this area, but this does not suit me, or who knows how to fix it?
Moreover, when it "sticks" the scroll of the page does not react (the mouse is to the left)
The issue was resolved by turning off the second screen, for some reason it was turned on
