When I tried this:
>> xinput set-button-map 11 0 2 3 4 5 6 7

It also disabled tap to click.

Is there a way to disable the physical left button of the touchpad without disabling the tap to click as well?

Nope as tap-to-click simulates a left-button click…

You can do the reverse though! I.E. disable tap-to-click and leaving the left button intact by setting the hysteresis of the tap-to-click so high that it would take one of these to activate it:

I thought it was possible since I manged to do it in Windows thru the driver’s settings. :thinking:

Here is the driver’s settings on windows.

That doesn’t mean anything: Linux is all about the hardware: if your hardware supports it, it’s supported. If your hardware doesn’t, it doesn’t…

E.G.

  • WiFi networks can be shared as a hotspot in Windows, but they can’t in Linux if your WiFi card cannot be set to Infrastructure mode: Windows “fakes it”
  • Left-click cannot be disabled on ElanTech, but can be on a Synaptic as there are 2 wires…

:sob:

I just tried Synaptics driver, left button doesn’t work anymore, which I want, but it can still accept hold event. :thinking:

I’ll try to look for disabling all the events passed to Left Button.
