I recently had some serious problems with my right mouse button on my Lenovo X240 touchpad. Out of a sudden I wasn’t able to use the right button… That’s not something I really liked and although I’m not the kind of person trying to resolve problems with reboot, that’s what I did.
Unfortunately it didn’t help.
Research on the net didn’t reveal anything useful and I tried to run
libinput-debug-events to get some more insight. It looked like the button
-event1 POINTER_BUTTON +23.08s BTN_RIGHT (273) pressed, seat count: 1 event1 POINTER_BUTTON +23.33s BTN_RIGHT (273) released, seat count: 0
gsettings set org.gnome.desktop.peripherals.touchpad click-method 'fingers'
but that was already set…
I then tried to use two fingers to tap-click and it worked as a right click. Hmmm, OK, maybe I need to set
gsettings set org.gnome.desktop.peripherals.touchpad click-method 'areas'
and yes, that was it.
No idea how this got changed, but it’s working fine now, again. Hooray!
