Public bug reported:

I have a Wacom Intuos VT M tablet in a setting with two monitors (laptop
+ external). Under an up-to-date Ubuntu Focal running X, if I map the
tablet to a single monitor it fails to map it more often than not. A
reliable way of getting failure is first connecting the tablet via
bluetooth and then via USB. The only way to revert to a correct behavior
is reseting X (ALT+F2 r). This is necessary even after rebooting.

I've noticed that, when not working well, the problem is that Mutter
sends the mapping data to the "Wacom Intuos BT M Pad pad" device, while
it should be sending them to "Wacom Intuos BT M Pad stylus" (this is
what it does when it works well).

Under Wayland it works well (well, the tablet buttons don't work under
Wayland but this is unrelated).
