Bug#830312: xserver-xorg-input-libinput lacks right-click support on touchpad!

[Francois Gouget <fgouget@free.fr>]

Until xserver-xorg-input-libinput gets fixed a workaround is to 
reinstall the xserver-xorg-input-synaptics driver and then adjust the 
Xorg configuration to get tap-to-click to work..

To get tap-to-click with synatics, copy 
/usr/share/X11/xorg.conf.d/70-synaptics.conf to /etc/X11/xorg.conf.d and 
add TapButton lines to the "Default clickpad buttons" section. That 
section will look something like this:

# This option enables the bottom right corner to be a right button on clickpads
# and the right and middle top areas to be right / middle buttons on clickpads
# with a top button area.
# This option is only interpreted by clickpads.
Section "InputClass"
        Identifier "Default clickpad buttons"
        MatchDriver "synaptics"
        Option "SoftButtonAreas" "50% 0 82% 0 0 0 0 0"
        Option "SecondarySoftButtonAreas" "58% 0 0 15% 42% 58% 0 15%"
        Option "TapButton1" "1"
        Option "TapButton2" "2"
        Option "TapButton3" "3"
EndSection

This should get you both tap-to-click and (regular) right-clicks.
