Sounds like your sensitivity maybe too high? https://askubuntu.com/questions/483707/14-04-touchpad-is-too-sensitive May be of value?
I saw that. And something's weird is going on with this thing.Yesterday, before I tried to disable tapping I wanted to get the middle button emulation to work.
"xinput list" told me that device "id=12" was something called "PS/2 wheeled mouse", and it offered a setting called "libinput Middle Emulation Enabled".
xinput set-prop 12 'libinput Middle Emulation Enabled' 1did what I wanted, and made both touchpad buttons emulate a middle button click.
I know I wasn't imagining this because I saved this command in the XFCE session manager to run at login.
I hunted around, and I saw nothing about disabling tap to click, so I gave up and went to sleep.
So, after reading your message, this morning I went back in. For some inexplicable reason:
1) xinput now tells me that id=12 is an "ETPS/2 Elantech Touchpad"2) This device does not have a 'libinput Middle Emulation Enabled' setting, and the command that I saved to run at session startup simply reports an error. The touchpad emulates the middle button click without this setting.
3) The touchpad no longer responds to taps, so the only thing for me to do is remove the session startup command, that no longer does anything.
I did not install any updates since yesterday. I'm fairly certain I'm using the same laptop today, that I used yesterday.
