Touchpad Tap problem Ubuntu 18.04 and Lenovo L340

by Tjax   Last Updated October 20, 2019 03:02 AM - source

I have installed Ubuntu 18.04 on Lenovo L340 notebook. Everything works fine, but time to time tapping on the touchpad does not work properly. I mean I tap on the touchpad but it does not do anything and I have to tap again. It does not happen too much I would say it happens 10 or 20 times within 8 hours work. Is this some kinda bug? Does anyone have the same experience? What can I do for this problem?
The output of xinput:

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ Synaptics TM3336-004                      id=10   [slave  pointer  (2)]
⎣ Virtual core keyboard                     id=3    [master keyboard (2)]
