Missing touchpad settings after update

Support System Updates

After last update (which upgraded plasma from 5 to 6), I missed touchpad settings in System Settings program and it says:

No touchpad found

But my touchpad is actually working!

Here is list of my inputs:

$ xinput list 
   Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ ETPS/2 Elantech Touchpad                  id=12   [slave  pointer  (2)]
⎣ Virtual core keyboard                         id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]

Let me know if you need any further information.

I can change the settings of touchpd using synclient without any problem. Also I enabled tapping for touchpad by creating following file and it worked successfully:

cat /etc/X11/xorg.conf.d/70-synaptics.conf                                                     ✔ 
Section "InputClass"
    Identifier "touchpad"
    Driver "synaptics"
    MatchIsTouchpad "on"
        Option "TapButton1" "1"
        Option "TapButton2" "3"
EndSection

I’m just wondering why System Settings could not detect my touchpad. Besides that, I prefer to change the settings of touchpad graphically.

I believe this thread may explain the systemsettings problem.

I agree with you :smiley:
Thank you, I’ll give it a try.

Though be aware that this will mean your xorg.conf.d config file won’t work. It’s a toss-up which is more useful. For me being able to configure the various buttons on my mouse in a config file was more useful than the more limited options in systemsettings.

Hmmm :thinking:
I agree with yout, I just wasn’t aware that systemsettings give me less options.
I think your answers were complete and mark this thread as answered. Thanks.
