I want to activate tap to click on my Lenovo e525 trackpad using libinput.
I have list-devices saying that its not activated.
I'm on Kubuntu 22.04.

How do I do this?

  • Could this question https://unix.stackexchange.com/questions/732153/xorg-conf-options-not-staying#comment1389403_732153 (and comments) help you finding your way (between xorg.conf settings / xinput command / DE settings) ? – MC68020 Jan 25 '23 at 16:56
  • BTW, Kubuntu means that your DE is KDE-Plasma. Right ? => System-settings > Input Devices > Touchpad – MC68020 Jan 25 '23 at 17:01
  • Yes - its KDE-Plasma – Greg Jan 26 '23 at 18:17
  • The Plasma UI touchpad tap section is disabled - this is soooo frustrating. – Greg Jan 26 '23 at 18:47
  • Then you might have a problem with the driver. Check into your bootlogs for infos regarding this particular device enumeration. Should in final be attached to some HID driver. – MC68020 Jan 26 '23 at 20:26

Assuming you're using Xorg, a simple way would be to create a new file under /etc/X11/xorg.conf.d :

sudo vim /etc/X11/xorg.conf.d/30-touchpad.conf

and add a basic configuration for the trackpad, like:

Section "InputClass"
Identifier "touchpad"
Driver "libinput"
  MatchIsTouchpad "on"
  Option "Tapping" "on"
  Option "NaturalScrolling" "on"
  Option "ClickMethod" "clickfinger"
EndSection

Worth checking that there is not already a file there for the touchpad, in that case simply add Option "Tapping" "on" to it.

The config should kick in after rebooting.

I'm sure however that there is a graphical way in KDE. If you go in Settings and search "Tap" you'll probably find it the correct switch.

  • There is a touchpad UI option but the "tap to click" option is disabled. Does that mean it cant be set? – Greg Jan 26 '23 at 18:41
