For my wife I setup an 2010 old HP 8100 Elite CMT with latest KDE Neon.
She is using it for group videoconferencing for dance lessons with up to 15 people.

I provided this integrated keyboard+touchpad (acting as mouse) since she is not on a desk so is easier to have just one thing in hand.

Problem is is working fine as the PC start, but after the videoconf started she didn't touch it anymore and after some minutes stopped reacting to keys or touchpad.
The only way to resume it is unpug and re-plug the wireless received on the USB port.

This is a problem for she since it's really not comfortable and also I fear breacking the small receiver, not used to being pulled and pushed all the time (already broken one in the past in this way)
