@Taffer Which distro are you on? On ubuntu, you could try synclient TouchpadOff=1

Or you could try xinput list to get the list of devices, and then xinput disable <device> to turn it off?

@JeremiahFieldhaven xinput only works for X11; I’m using Wayland. And it’s not a Synaptics touchpad. 🤷

I think KDE Plasma 6 doesn’t have a way to do this, and it’s a weird thing to miss out on.

This is low-key driving me nuts.

Found the touchpad via /sys/bus/i2c/... and a tempting "inhibited" file with a 0 in it; this doesn't seem to inhibit the touchpad. 🤷

Progress(?) today…

Using kcfg, I re-enabled the touchpad. Then killall -HUP kwin_wayland… seems to have enabled the touchpad, but also behaved as if KDE had crashed and been restarted. My apps were killed. Not quite what I wanted.

Tried using PyQt6 to send a DBus message to KWin that I thought would reload all the configs; no apparent effect. Wonder if I need to be root?

The org.kde.KWin DBus has a /component/kcm_touchpad that has interesting
Get(interface, property) and Set(interface, property, value) methods. I
can't find any current kcm_touchpad info though, just ancient source repos.

@Taffer in case your environment uses Qt 6.6 or newer, your apps should survive a crash/restart of #KWin (on #Wayland):

@eliasp cool, not sure what version I’m using, I panicked and logged out/in to make sure everything was happy 😄
