Did you make sure to set Edit → Input Devices → NetworkTablet to Screen? Other devices like a mouse can’t be used together.
Wayland and MIR
So considering that x.org is going out the window fairly soonish I guess is there any intent to support Wayland on distros using that and possibly for Ubuntu folks the MIR display server?
The display server shouldn’t matter. GfxTablet only uses the Linux uinput subsystem.
Oh yeah I forgot about how things are changing used to be X.org did the input and all that crap but that’s going away Wayland ain’t it?
