SUMMARY

When scrolling with two fingers (sometimes three, when the third get tired and touches the touchpad) the context menu opens (unwanted/contra-productive). I use hardware button(s) for that (Thinkpad). Currently, one has to chose "Middle click" or "Right click" and both are "problematic", they trigger the context menu.


So in brief, am requesting an option to do nothing under "Two-finger tap".
STEPS TO REPRODUCE
1. Use two fingers for scrolling
2. 
3. 

OBSERVED RESULT
Context menu opens

EXPECTED RESULT
No unwanted/unexpected context menu

You can already turn off taping entirely. Do I understand that you want to be able to do single-finger taps but not two-finger taps? Or is it acceptable to turn of tapping entirely (as I do, personally)?

Yes, I would like to be able to single-finger tap, but disable two-finger-tap. Two-finger-scrolling is often being interpreted as two-finger-tap.

Thanks. Unfortunately that isn't something that I believe Libinput currently supports. You'd need to request support from them before we can add a setting to toggle the behavior.

You can do so here: https://gitlab.freedesktop.org/libinput/libinput/issues
