That would be a very welcome change, without doubt, thank you.
However, I can't help wondering, would it be more productive to allow libwacom
to work with just any basic tablet, without the need to add each one to the
Actually, libwacom is not tight to Wacom devices at all (or should not
be). It is just a database of devices to add what the kernel doesn't or
can not provide. The things that are in the db are for example how the
buttons are physically mapped on the device, what is the actual layout
(one svg file), if there are LEDs attached to the tablet.
All this needs a fine per-device tuning. We can add a generic
Huion/UClogic tablet too, but having a specific per-device definition
allows to show the exact mapping of the buttons on the overlay when
setting the functions.
I agree, that's a nice feature. However, I think being able to configure all
the applicable Wacom driver features relatively comfortably, even if the
tablet on screen doesn't exactly match your tablet, is still a win, compared
to not being able to do it.
For the unknown tablets we can just draw abstract tablets, emphasising that
control locations on the screen don't map to the actual locations. For
example, have the tablet drawn like an exploded diagram: surface, buttons,
dials - all separate. Something like this:
Buttons: * * * * * * *
Dials: O O
Work area: +------------+
I think the users will be able to figure out the mapping by experimentation.
While it's just about possible to keep an up-to-date database of Wacom
tablets, I don't think we'll ever be able to list all those generic tablets
out there. Meanwhile a lot of people are left in the cold of xsetwacom and
not a reason to give up, IMO. most of these generic tablets are relatively
simple, so adding a libwacom entry should be a matter of minutes.
we'll never get full support of everything, but perfect is the enemy of good
