Install xf86-input-wacom from source
masterIf your Wacom device is not working out-of-the-box, you may be using a newer device than what your distribution provides, running an older operating system, or requiring a specific bugfix. In these cases, you should install the driver from source. Detailed instructions for building and installing the driver can be found in the project wiki.
