I’m using KDE. For past 2-3 weeks I stopped using touchpad and switched to wired mouse. Now after this time I tried to use touchpad and it has gone laggy. I’m not talking about pointer speed here. It literally feels laggy. If I move my finger from one point to other pointer doesn’t go to corner immidiately (You know what I’m saying right? I can literally see it lagging behind the input, which was not the case earlier.)
I’ve tweaked setting, increased pointer speed but still I can notice the lag. Even the two finger tap doesn’t work.
I’ve cleaned the surface of the touchpad with alcohol (Spirit) and removed the dust fin the gap with blower but got no result.
Can anyone help me out to fix this? Also is there anything we can do to get windows likke gestures features for touchpad?

I’ve been having the same issues your talking about forever. Just randomly out of nowhere the touch pad just “stutters” when moving it. Then after a little bit without doing anything it will go back to normal. I’ve also switched to mostly using a wired mouse when I can but I can’t always use it in every place. Makes me wonder if it’s just bad drivers. I have an Asus Q524UQK laptop.

@Fabby Hmmm… it’s not a windows precision touchpad?

Does it happen if the USB mouse is disconnected? Please try the following:

sudo rmmod hid-multitouch && sleep 2 && sudo modprobe hid-multitouch

both with the USB mouse connected and disconnected and see if changes anything.
