Today I installed the latest KDE version ( kde-18.0.4-stable-x86_64) on my Asus X455L laptop, after the installation I noticed that the touchpad was kinda jumpy, imprecise and drifty (sorry for the choose of words to describe it). It is very difficult to use the touchpad.
I tried to configure the touchpad using the settings but most of the options were grayed out.
After googling my issue one of the answers said to use synaptic instead of libinput, so I installed synaptic using pacman, this helped with the greyed out options but the issues on my touchpad still persists, even after trying to tweak the values.
At the moment im kinda lost and dont know what else to try, so any help is appreciated.
