It seems to have been an incompatibility with the xf86-input-evdev-git package. Installing the package from the repos lets it work.
Does GfxTablet give you a Touchscreen or a Tablet?
I’m trying to get Krita working with GfxTablet. Presently it doesn’t on my system, because the input driver gets recognized as a touchscreen instead of a tablet. I’m interested to know if this is distro level weirdness - I am preparing a patch to the driver to fix it, but I want to know if it’s going to mess with non-Debian distros.
So, can any users quickly check
most /var/log/Xorg.0.logafter they start
networktablet, and tell me if the thing is being detected as a touchscreen or a tablet?
