I've had an intermittent problem with my laptop touchpad
It doesn't stop working completely, but after my laptop has been on and running for an hour or so this problem starts. When I first touch the pad the mouse cursor won't move for a couple of seconds. I have to keep my finger on the pad for about 2 seconds, and then the cursor moves. After I restart the problem goes away and cycle starts again, similarly if I log out and back in again it can solve the issue temporarily.
Pad clicks work fine, as does the touchscreen, but scrolling with two fingers does not.
I have reinstalled the driver. I've also tried using procexp to search for 'hook.dll' in case I could spot a program using it.
Recent changes are installing Windows 11 (in October, about a week before this started), and uninstalling Touchpad Blocker (a couple of days after this started to see if it was the problem).
Laptop is a Dell XPS 15 7590 purchased in June last year.
Can anyone suggest anything else I can try to diagnose this?
