I followed the suggestion but with no luck. Here is what I’ve done:
I checked my /usr/share/X11/xorg.conf.d/50-synaptics.conf and nothing out of the ordinary, tapping should work. Installed gpointing-device-settings and it shows as if tapping was enabled…
Then on the page you gave me, I stumbled on this:
Then it hit me. During Gnome 3.20 update they moved from synaptic drivers to libinput so I installed it but didn’t get rid of synaptic drivers. Can this be the cause? I tried the solution from arch wiki and added MatchDevicePath “/dev/input/event*” to my /etc/X11/xorg.conf.d/50-synaptics.conf file. No change
So I decided to remove synaptic xf86-input-synaptics. Rebooted and… no change… Pad is working, two finger scrolling is working but no tapping is detected.
At the moment I’m out of ideas.
