[SOLVED] 2-finger tap causes middle click instead of right click

I have just re-installed Arch and discovered that I can't open contextmenus with the touchpad. It used to be that 2 finger tap would fire RMB but it fires MMB.

This depends on your config and general environment, what are you using?

Re: [SOLVED] 2-finger tap causes middle click instead of right click

i3 with Xfce4 settings daemon and a few Gnome apps installed.

I always had an issue with tap to click not working. I fix it by adding this to /etc/X11/xorg.conf.d
```
Section "InputClass"
  Identifier "touchpad"
  Driver "libinput"
  MatchIsTouchpad "on"
  Option "Tapping" "on"
  Option "TappingButtonMap" "lmr"
EndSection
```

to enable tap to click. I never had a problem with it. I may actually disable it and relogin to see if it's any different, but I doubt it will have an effect. It seems like the default changed from 2 finger tap causing RMB to 2 finger tap causing MMB.

And this is the current configuration for the touchpad:
```
Device 'DLL0665:01 06CB:76AD Touchpad':
    Device Enabled (177):    1
    Coordinate Transformation Matrix (179):    1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000

    libinput Send Events Mode Enabled Default (300):    0, 0
    Device Node (301):    "/dev/input/event10"
    Device Product ID (302):    1739, 30381
    libinput Drag Lock Buttons (331):    <no items>
    libinput Horizontal Scroll Enabled (332):    1
    libinput Scrolling Pixel Distance (333):    15
    libinput Scrolling Pixel Distance Default (334):    15
```

I don't see an option here that would relate to this.

I have noticed that tap right-click works actually, but it's set backwards. A 3-finger tap will trigger right-click. 2-finger tap will trigger middle click. It should be vice versa.

Re: [SOLVED] 2-finger tap causes middle click instead of right click

Solved. it seems like TappingButtonMap does not work anymore. I changed my config file from:

Section "InputClass"
  Identifier "touchpad"
  Driver "libinput"
  MatchIsTouchpad "on"
  Option "Tapping" "on"
  Option "TappingButtonMap" "lmr"
EndSection

to

Section "InputClass"
  Identifier "touchpad"
  Driver "libinput"
  MatchIsTouchpad "on"
  Option "Tapping" "on"
  Option "TapButton1" "1"
  Option "TapButton2" "2"
  Option "TapButton3" "3"
EndSection

for reference, this is a file in xorg config. I.e. /etc/X11/xorg.conf.d/31-touchpad.conf

by the way, I found inspiration from this wiki page: https://wiki.archlinux.org/title/Touchp … ed_options - and in that config file 2-finger tap was the middle click also . It's weird how it's suddenly a default. I have never seen it earlier, it was always 2-finger tap triggering right click.
