No touchpad found

Dear Archers,

Recently I ran into a problem after an update that all of the sudden my touchpad on my Dell XPS was not working anymore (reboot after the update due to new kernel updates...)
I'm also using KDE Plasma and noticed in the System Settings that indeed the touchpad is not detected anymore (at least according to KDE).
It says "No touchpad found".

However, according to xinput list it detects it:

 Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ Microsoft Microsoft 5-Button Mouse with IntelliEye(TM)	id=10	[slave  pointer  (2)]
⎜   ↳ ELAN Touchscreen                        	id=11	[slave  pointer  (2)]
⎜   ↳ PS/2 Synaptics TouchPad                 	id=18	[slave  pointer  (2)]

Also in the Xorg.0.log I find the following entries:

grep -e "Using input driver 'libinput'" /var/log/Xorg.0.log
[     7.236] (II) Using input driver 'libinput' for 'Power Button'
[     7.321] (II) Using input driver 'libinput' for 'Video Bus'
[     7.481] (II) Using input driver 'libinput' for 'Power Button'
[     7.522] (II) Using input driver 'libinput' for 'Sleep Button'
[     7.584] (II) Using input driver 'libinput' for 'Microsoft Microsoft 5-Button Mouse with IntelliEye(TM)'
[     7.798] (II) Using input driver 'libinput' for 'ELAN Touchscreen'
[     8.008] (II) Using input driver 'libinput' for 'Integrated_Webcam_HD: Integrate'
[     8.088] (II) Using input driver 'libinput' for 'Intel Virtual Button driver'
[     8.129] (II) Using input driver 'libinput' for 'Intel HID events'
[     8.167] (II) Using input driver 'libinput' for 'Intel HID 5 button array'
[     8.207] (II) Using input driver 'libinput' for 'Dell WMI hotkeys'
[     8.311] (II) Using input driver 'libinput' for 'AT Translated Set 2 keyboard'
[    12.125] (II) Using input driver 'libinput' for 'PS/2 Synaptics TouchPad'

So this gives me at the very least the hope that the touchpad is not broken.

My config in /etc/X11/xorg.conf.d/50-libinput.conf looks like this:

Section "InputClass"
    Identifier "touchpad"
    Driver "libinput"
    MatchIsTouchpad "on"
        Option "TapButton1" "1"
        Option "TapButton2" "3"
        Option "TapButton3" "2"
        Option "VertEdgeScroll" "on"
        Option "VertTwoFingerScroll" "on"
        Option "HorizEdgeScroll" "on"
        Option "HorizTwoFingerScroll" "on"
        Option "CircularScrolling" "on"
        Option "CircScrollTrigger" "2"
        Option "EmulateTwoFingerMinZ" "40"
        Option "EmulateTwoFingerMinW" "8"
        Option "CoastingSpeed" "0"
        Option "FingerLow" "30"
        Option "FingerHigh" "50"
        Option "MaxTapTime" "125"
EndSection

I have the following packages installed:

aur/libinput-touchpad 1.0-3 (+0 0.00%) (Installed)
extra/xf86-input-libinput 0.28.2-1 (33.9 KiB 155.0 KiB) [xorg-drivers] (Installed)
extra/libinput 1.13.1-1 (205.2 KiB 878.0 KiB) (Installed)

However, the touchpad is still not working at all.

Anything specifically missing here?

Do you have some hints what the problem could be related to, or what else should I try?
I'm pretty desperate at this point (and yes I have read the wiki post of libinput)

thanks a lot in advance,
theresa

Re: No touchpad found

Did you rebuild libinput-touchpad?

Moving to AUR Issues...

Re: No touchpad found

Why are you using a package that just installs 1 file  to usr/share/X11/xorg.conf.d/30-touchpad.conf ?

Try removing libinput-touchpad package.

Re: No touchpad found

Ok, this can be closed now.
It seems this was fixed with the latest kernel update.

I'm now running
4.19.37-1-lts
