@halla Hey, yes, I remember, but it was the generation before the MobileStudio, the Wacom Companion, right? (I know they made Companion 1 and Companion 2).
Sure, I remember launching an Ubuntu live ISO on your model with Animtim and @raghukamath at a Krita sprint. Many things worked out of the box, probably on a 16.04LTS days.
True for on-display keyboard on Linux. Probably now the touch keyboard support is better (but with what I saw on my SurfacePro3, not sure I can call it ideal 😺) .
