Thanks @tusch001 this was very helpful and worked on the stable Focal channel with Snapz0r installed. I would recommend one change: the sed command should read-
sudo snap run libinput.list-devices | sed -n '/himax-stylus/,+20p'
instead of:
sudo snap run libinput.list-devices | sed -n '/himax-stylus,+20p'
A few practical questions for you or anyone else:
What kind of daily battery life are you seeing for the stylus, over how many hours of use?
Do we know if it's compatible with other UT devices?
In Libertine, is there a convenient way to anchor the stylus' nib to things like scroll bars? I've been trying to scroll up/down on VS Code but it's quite cumbersome and feels like I have to press it multiple times then do a small flick to get it to scroll by a little bit every time. Kind of much like using my finger (it's just that the nib is so much more small and thus more of a precision instrument compared to anyone's finger!). Unfortunately I need to figure out how to get my Volla Keyboard accessory working again and thus I don't have access to its touchpad and a mouse cursor (I've been using a bluetooth keyboard instead), so this would be a great workaround for the time being if it's possible.
On an OS level:
Hopefully someone can formally implement this into an OTA upgrade for the tablet on Noble and potentially even a maintenance release on Focal? The code changes look straightforward if they're just about changing the udev rules and such. I have been working on contributing to app development on and off but as a) the tablet is a bit of a daily driver for me and I like to keep it on the stable channel and b) contributing to OS patches is something I'm not really familiar or comfortable with, it would be excellent to see this happen if someone else can help out.
