Comment 1 Nate Graham 2024-06-19 18:55:27 UTC
Did you remove or mask the Libinput drivers, and you were previously using the Synaptics drivers? If so, that's the cause: Synaptics drivers are not supported in Plasma 6.
Comment 2 J Vernet 2024-06-19 19:26:44 UTC
Sorry, I uninstalled Synaptics per this:

<https://discuss.kde.org/t/settings-says-no-touchpad-found/14139>

(even though my issue differed, as my touchpad wasn't working and not 
just undetected)

There was no result, so I didn't include it in the report. My mistake.

Does the issue reproduce in a new clean user account on the same machine?
Comment 4 J Vernet 2024-06-20 17:34:31 UTC
Created new, clean account. Hard restarted. No change.

Comment 5 Nate Graham 2024-06-20 18:10:28 UTC
Ok, so this suggests a missing package or a root-level configuration issue on the machine.

To rule out other possibilities, when was the last time this worked? And when id did work, was it showing the old Synaptics UI (with a test area and configurable inertia) or the Libinput UI with a "left handed mode" checkbox?
Comment 6 J Vernet 2024-06-20 20:16:39 UTC
Sorry, the last time it worked was when it was running Win10 previous to 
the neon install (this was the first Linux install on this machine)

So given your request, I'll try another install, and if it starts 
working again, I'll try to reverse engineer why and update

Thanks for your help!

Aha, if it has never worked on Linux, then I think it's more likely this is a driver issue, I'd recommend reporting it at https://gitlab.freedesktop.org/libinput/libinput/-/issues/.
Comment 8 J Vernet 2024-06-20 21:20:32 UTC
(I had a feeling about that)

Thank you, Nate!
