Hello,
I'm using KDE neon, a very eligent desktop with lots of customization and modern look. So far so good. The only limitation is my touchpad stops working frequently. See the below screenshot,
It was working...

but then it stoped working,

When it stops working I only lose edge scrolling, tap to click option everything else works fine though. A restart always solves the problem but it's not very practical all the time. It also happend when I was in Manjaro KDE, but didn't happen in linux mint. I'd really appreciate if anyone can give light to this problem.

best regards,
Sobuj
