When Gnome isn't able to detect a Wacom pen there is no way to change the buttons on Wayland
On my Wacom tablet the tablet is detected by the gnome-control-center correctly and I can properly configure it via the GUI, but my pen doesn't get recognized.
The pen is a standard pen, which libwacom-list-local-devices lists as generic fallback. There is no way to configure the 2 buttons that exist on this pen on Wayland, which possibly creates a new bug, detailed below.
Because my problem is that the pen never issues left mouse clicks on dropdowns/menus/etc. and that seems to be an old issue discussed here. The solution provided is, to use the xsetwacom commandline utility to remap the button 1 as left click (which should be default but who knows whats going on here), but this is not supported under Wayland, since everything moved into libinput, etc. So now my pen doesn't send the right signals and since gnome-control-center provides no way to remap my generic pen, I can't remap my pen on Wayland, which leaves the pen in a highly broken state. On Xorg the pen also isn't recognized but works fine out of the box, but afaik X uses the old wacom input driver and not libinput as backend.
Steps to reproduce:
- Open GNOME Settings
- Go to the Wacom settings
- There is no pen showing up even though I have it layout on the tablet
Information to my setup:
- Lenovo Thinkpad Yoga 3rd gen
- Wacom Tablet isdv4-5146
- Thinkpad Pen Pro (which comes integrated in this machine)
- Fedora 29 Gnome Wayland
