<pre>Recently I found libinput supports multi-finger gestures as an alternative to
touchpad buttons. Most of the times it's amazing, except when it doesn't work.
Sometimes touching the touchpad with 3 fingers ends up with no visible effect,
othertimes its effect is as if I touched with two fingers (e.g. a context menu
pops up).
The evemu-record is done with a few attempts to make the triple-button gesture
over a terminal. Some attempts resulted in no visible effect, whereas when this
detected as a two-fingers click, I had to make a single click to dismiss the
menu.
Note: the very last triple click in the record did succeed.
laptop: SAMSUNG NP305V5A
touchpad: x=103mm, y=53mm. (I'm traveling, measures are done with a checkered
notebook)
libinput version tested: 1.9.901.r0.g0ac4a148 (git)
