Jumping mouse pointer on 24.04 makes browsers unusable

My mouse cursor moves all on its own and disrupts web pages. My Dell Latitude 3120 has a touchscreen and touchpad (two pointers) but my xinput list shows 4 slave pointers so there may be a conflict. I do not have a mouse and I am not sure of which pointer is for the touchscreen.

mm@mm-dell-lpt:~$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ DELL0A33:00 04F3:3082 Mouse id=10 [slave pointer (2)]
⎜ ↳ DELL0A33:00 04F3:3082 Touchpad id=11 [slave pointer (2)]
⎜ ↳ WDHT1F01:00 2575:0907 id=12 [slave pointer (2)]
⎣ Virtual core keyboard

I have read "Dell Precision and XPS Ubuntu Touchpad Fix: Solutions for Touchpad and Mouse Issues on Ubuntu" but this article references different devices and the solutions suggested do not function on my machine.
Is their a simple way to block some of these pointing devices because there seems to be some conflicts?
Thank you, Larry

Well, have a look at

IMHO, that looks like a hardware problem. I am using USB mouse and I have disabled my touchpad via System > Preferences > Hardware > Mouse dialogue

Hopefully, disabling touchpad would help to isolate a source of your problem.

Good luck!

P.S. Just for a reference

Hi, @LWilliams and welcome to the Ubuntu MATE Community!

Actually, one of my side hustles is repairing older Dell's, specifically Latitudes, and it is common to see problems with the touchpad. The 3120, however, is just a couple years old so I would be surprised if it is a hardware issue but it is certainly possible.

I would do as @ugnvs suggested and hook up a USB mouse, disable the touchpad and then test it and see if you are still having the same problem.

Thank you, I tested the touchscreen and it is faulty. I disabled the touchscreen on the bios and the touchpad works great.
