Synaptics driver is installed

❯ eopkg info xorg-driver-input-synaptics
Installed package:
Name                : xorg-driver-input-synaptics, version: 1.9.2, release: 32

The touchpad is working, but not all functionality is working.These are not working:

Tap to click
Two finger tap for right click
Three finger tap for middle click

If you run this from a terminal does it show that it's not found? Mine for example with Plasma 6 and touchpad (my settings shows all the tickboxes etc)

kcmshell6 kcm_touchpad
kcm_touchpad: Touchpad found: "SynPS/2 Synaptics TouchPad" ("event6")

Here are my results:

Dell XPS - where problem reported

❯ kcmshell6 kcm_touchpad
qt.qml.typeresolution.cycle: Cyclic dependency detected between "qrc:/qt/qml/org/kde/desktop/private/TextFieldContextMenu.qml" and "qrc:/qt/qml/org/kde/desktop/MenuItem.qml"
qrc:/libinput/touchpad.qml:691: TypeError: Cannot read property 'supportsScrollFactor' of null

This brings up the touchpad settings pane, which says "No touchpad found"

Lenovo Flex - does not have the problem

On the Flex, the touchpad works as expected.

$ kcmshell6 kcm_touchpad
kcm_touchpad: Touchpad found: "ELN4690:00 04F3:304B Touchpad" ("event7")
qt.qml.typeresolution.cycle: Cyclic dependency detected between "qrc:/qt/qml/org/kde/desktop/private/TextFieldContextMenu.qml" and "qrc:/qt/qml/org/kde/desktop/MenuItem.qml"

This brings up the touchpad settings pane, with all settings showing

As seen by the output, kcm_touchpad has different errors on the two systems. On the Dell, it looks to me like the error from the back end is the issue

The system does detect the touchpad

I found an upstream issue which also has the solution. The bug I experienced may be due to Plasma dropping synaptics config

To reiterate the soluion here:

I had xorg-driver-input-synaptics installed because in Plasma 5, it was necessary to be able to see all options for my touchpad. (Otherwise, some checkboxes were not present)

After uninstalling xorg-driver-input-synaptics and rebooting, I now see all settings in the Touchpad settings. Closing this issue.
