I’m trying to get this external USB touchpad to work because it eases my carpal tunnel. It works perfectly on a PC running Kubuntu. On My Pi4 running Manjaro it’s not useable. The pointer works for a bit but then randomly jumps around or simply doesn’t respond for a few seconds.
I’m using Wayland and have changed everything under Touchpad in System Settings but with no difference. I also tried an X11 session and that was much, much worse.
I believe the touchpad is a Windows precision compatible touchpad. On Kubuntu (X11) it’s recognised by libinput and I had to modify a file in xorg.conf.d to get tapping to work. Tapping works on Manjaro without modifying any files, indeed the equivalent file doesn’t even exist. It seems like Manjaro recognises it better, but the randomness suggests a kernel or hardware problem?
