So… as I want to have tapping on my touchpad, i had to enable it via synclient.
I followed the instructions on https://wiki.archlinux.org/index.php/Touchpad_Synaptics .
To enable tapping i used the command: “synclient TapButton1=1”.
After that tapping worked for me… too good. So whenever i typed, i pressed a button. To fix that i had to use “synclient PalmDetect=1” and for it to work properly “synclient PalmMinWidth=8”.
After that it worked for me (on my thinkpad a275).
To make the changes permanant i had to edit the config file located in
The touchpad section config was edited like that:
Section "InputClass" Identifier "touchpad catchall" Driver "synaptics" MatchIsTouchpad "on" Option "TapButton1=1" Option "PalmDetect=1" Option "PalmMinWidth=8"
So after that the touchpad was working with tapping and i could move on to config the other things.
