Try to install:
sudo pacman -S xf86-input-libinput
If it doesn’t cure the problem, it is always possible to uninstall it with:
sudo pacman -Rcnsu xf86-input-libinput
@just actually i shouldn’t have deleted the “Wifi not working” part. Tthe first time i started the OS, i had internet connection. when i turned it off and then on, no connection. It’s one problem after another…
Neither the topic’s title nor the OP speaks about Wi-Fi.
Mixing two or more problems in one post (topic) is a bad practice.
