Multi-touch touchpads are the standard these days. I searched around for good support, ideally out of the box, on modern Ubuntu. To be more specific: I'm on Kubuntu 20.04 without any relevant PPAs.
Most solutions seem to involve libinput-gestures which, to be honest, is a super hacky solution. It calls
libinput debug-events under the hoods and reads its STDOUT. I'm happy to hear that this works for many people, but I would prefer to not have to use this.
I also found packages
xserver-xorg-input-mtrack but both of them have not been touched in many years and they seem to rely on synaptics, not the more modern libinput.
I wonder if someone knows of any modern (ideally KDE-based) solutions for getting swipes and pinches etc. to work. Or if there are any KDE tickets to follow that deal with this.
