Stuttering mouse and black screen on the left side of the screen

A greeting to everyone, I’m Italian, and I’m using an online translator. I hope I’m clear!
I am an inexperienced and occasional user of Linux. I have installed Zorin 17.1 on an old and slow Gigabyte mini PC (with 14nm Intel® N3150), and overall, it works quite well and fast. Unfortunately, I am encountering an issue: when I move the mouse cursor toward the left edge of the screen, right near the edge, the cursor freezes for a few seconds and then resumes, effectively causing stuttering. Additionally, sometimes the screen goes black for 2-3 seconds.
Hoping that there is a solution, and that it is within my reach, can you help me?

Have you tried Xorg instead of Wayland (default) at Login. Click on your login then look for gear wheel icon on screen and click that to change.

Thank you for the response; as soon as I get home, I’ll try

“I followed your suggestion: indeed, in Xorg now when I move the mouse cursor to the left side of the display, the mouse still stutters, but it no longer turns the screen black. At this point, the PC is much more usable. Is there anything else I could try to resolve the mouse stuttering?”

Have you looked at Settings>Touchpad and Mouse and had a play there to see if anything in set-up helps. You can also test mouse operation there.

certainly, it was the first thing I did, but there is no voice that solves my problem: the pointer stops at 1 or 2 centimeters from the left edge then continuing to move the cursor unlocks and seems to snap then resumes. At least now (since I use xorg) there are no more black screens!!!
