I don’t use drawing tablets I’m just here for the cute catgirl.
I have a Xencelabs pen tablet + their Quick Keys peripheral. I can’t seem to find any documentation regarding specific support for it on Linux.
The official driver does nothing for usability under Gnome on Fedora 42. Removing the driver made it work better, but it was still finicky. I’ve since switched back to KDE Plasma, and the tablet works pretty well out of the box. There’s no way to configure the buttons on the tablet, and I don’t know what they do, if anything. The pen has 3 buttons but the config only recognizes 2.
I’m hopeful this means better support is coming. It kills my motivation to use it sometimes when functionality hits a snag.
