Hi, guys
I hope smarter people that me can help with my touchpad buttons not working.
Ibinput, I know is the default for input devices and combined with libinput-gestures,
I’ve managed to get touchpad working with single and double taps.
And xf86-input-libinput thinking it might add to the solution.
However, still no button functions. Any suggestions welcome.
Test with:
$ xev
make sure cursor and focus is in the appearing window, keep the terminal behind it, then press the touchpad buttons. If there’s an output in the terminal, then it’s actually detected, maybe just incorrectly mapped.
You can give it a go with the older synaptics (I use this)
sudo pacman -Syu xf86-input-synaptics
(unless you have set some config somewhere … it should take precedence over libinput once installed)
I qam not familiar with it … but I would suppose not - it seems to work through xinput.
Here is what I did:-
sudo pacman -Rs touchpad-indicator
Thinking this might cause some conflict, then:–
sudo pacman -Rs xf86-input-libinput
checking dependencies...
error: failed to prepare transaction (could not satisfy dependencies)
:: removing xf86-input-libinput breaks dependency 'xf86-input-libinput' required by xorg-server
But as you can see, I cannot remove “xf86-input-libinput”.
But I did:-
sudo pacman -S xf86-input-synaptics
>>> xf86-input-synaptics driver is on maintenance mode and
xf86-input-libinput driver must be prefered over.
:: Running post-transaction hooks...
(1/1) Arming ConditionNeedsUpdate...
But as you can see xf86-input-synaptics driver is on maintenance mode and xf86-input-libinput is used.
Now I must be missing something but it is beyond my ability.
Are you sure?
After a restart check
xinput list
Then, depending on the number associated with your touchpad, ex, 12:
xinput list-props 12
You were right. However both buttons still don’t work.
Trackpad One finger tap = Left Click
Trackpad Two finger tap = Right Click
xinput list-props 19

That does show it using libinput.
If you want to try and force synaptics then maybe you can use a conf file … heres mine:
/etc/X11/xorg.conf.d/71-synaptics.conf
Section "InputClass"
Identifier "touchpad catchall"
Driver "synaptics"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Option "TapButton1" "1"
Option "TapButton2" "3"
Option "TapButton3" "2"
Option "VertTwoFingerScroll" "on"
Option "HorizTwoFingerScroll" "on"
# Option "VertEdgeScroll" "off"
# Option "HorizEdgeScroll" "off"
# Option "CircularScrolling" "off"
# Option "CircScrollTrigger" "2"
# Option "EmulateTwoFingerMinZ" "40"
# Option "EmulateTwoFingerMinW" "8"
# Option "CoastingSpeed" "0"
# Option "FingerLow" "30"
# Option "FingerHigh" "50"
# Option "MaxTapTime" "125"
EndSection
Section "InputClass"
Identifier "touchpad ignore duplicates"
MatchIsTouchpad "on"
MatchOS "Linux"
MatchDevicePath "/dev/input/mouse*"
Option "Ignore" "on"
EndSection
(obviously the commented out options have no effect … they are left for convenience for you to tweak)
Hi @cscs,
Thanks for the config file. I’m setting up laptop for my sister and it came to me with no OS. You would not believe it! A bit more searhing and ths dell model has a battery problem.
The battery is located under the tackpad and buttons. Over time the battery case swells[still works] and prevents the pad keys from working.
Solution:- Remove battery plugin A/C and trackpad and button work. Now she will have to spring for a new battery. Thanks again for your help.
