Wacom Intuos Pro tablet on Wayland: How we should get the initial mode using the Wayland protocol
I am actually checking the tablet support on Wayland for Kwin (Mutter) and Qt... and writing a patch for Kwin to add missing messages.
I don't understand in https://wayland.app/protocols/tablet-unstable-v2#zwp_tablet_pad_group_v2:event:mode_switch how an application can retrieve the initial tablet mode. Could someone check this point. If the protocol is missing something, then it must be fixed. I opened an issue about this on the Wayland issue tracker.
Currently, pen pressure seems to work as expected on Fedora 36/37 Kwin Wayland with the beta.
