In my ubuntu, the Asus Pen that came with my Asus T103H was not supported. It is not shown in Gnome Control Center (Wacom Tablet) but it is listed in
xinput as a Pen. In the Xorg log, it shows that there is no available driver for the Pen installed.
What driver do I need to install, or what configuration to I need to add for the Asus Pen to work in applications such as GIMP and Xournal?
