Description Matthew Wilcox 2018-04-05 18:10:41 UTC

I have an HP Envy x360 with a synaptics Clickpad.  The right and middle buttons used to be faked but after a reboot are no longer being faked.  This is current Debian testing with libinput 1.10.3-2, kernel 4.15.0-2, 

libinput debug-events --device /dev/input/event1 --set-click-method=buttonareas shows BTN_LEFT BTN_RIGHT and BTN_MIDDLE

libinput debug-events --device /dev/input/event1 --set-click-method=clickfinger shows only BTN_LEFT.

$ sudo libinput debug-events --device /dev/input/event1 --set-click-method=buttonareas

libinput list-devices shows you the libinput defaults, the default for the click methods is marked with *. What does that command show? 

If it's still on button areas, the issue is higher up in the stack. GNOME 3.28 changed the defaults from button areas to clickfinger, so this is likely the source of the problem. gnome-tweak-tool should let you change, the gsettings commands are:

To fetch the current value

  gsettings get org.gnome.desktop.peripherals.touchpad click-method 


To see the options available:

  gsettings range org.gnome.desktop.peripherals.touchpad click-method 

To change:

  gsettings set org.gnome.desktop.peripherals.touchpad click-method $OPTION


Closing this bug, please re-open if it turns out to be a libinput bug after all.
