Hello,
I bought a new labtop dell 5481 installed netrunner 2019.04 rolling release. After initial install I activated tapping from setting -\> input devices -\> touchpad. After upgrade of all system via octopi, tapping is no longer working. Some of the debugging command output are below. As far as I understood, there are more buses or touchpad devices. Synaptic vs. dell. Help much appreciated.
xinput --list command output is below

Did you reboot after the upgrade?
Did you install xorg-xinput as it’s not installed by default?
Which dell 5481 is this?
(inspiron or vostro)

Hello thank you for the response
I restarted many times.
Dell vostro 5481.
I did not install xorg, it was available, but I installed only the x tools xev and xinput…They were small downloads with octopi.

OK, but I didn’t ask if yoou installed xorg, that’s a given ATM.
I asked about xorg-xinput, which is the full package name for xinput.
At any rate, xorg uses libinput for touchpads by default, to use the evdev or synaptics drivers you would first need to edit and/or add some xorg files.

Hello,
Again thank you for the fast response. All I want is to use KDE Touchpad interface. Touchpad interface in KDE Settings does not comply currently. I have no bios options for simple touchpad settings as well.
Yes now I am using libinput conf file placed in /etc/X11/xorg.conf.d, it took some time to get it right to solve the problem temporarily. It did. It uses libinput driver and options. However I have another, older dell latitude labtop running latest netrunner which does not need such a tweak. I do not want to maintain files…
Do you have suggestion? Is it a bug?

More than likely they are using different chips (aka dell, synaptic, alps, etc.).
It’s probably more of a game of catch up between kernel drivers, and/or libinput, etc.
Could also be a bug (aka regression) somewhere as well.
