Is this an official / supported Linux driver from Wacom?
Wacom provides technical resources to help keep the linuxwacom driver up to date, but leaves it ultimately in the hands of the community. Wacom makes no guarantees about the timeliness or availability of any specific updates. If you have questions or need support, please file a bug report at the linuxwacom site. IT departments using the linuxwacom driver across a fleet of systems may consider contacting their Wacom sales representative for other support options.
Do I need to install all the driver components for my tablet to work?
Your system will need many of the driver components in place for your tablet to work, but only rarely will you have to install anything. Most Linux distributions install all necessary components by default, allowing Wacom tablets to work out of the box. If one component needs updating (e.g. libwacom) only that component needs to be manually installed; you should continue to use the system-provided version of all other components.
What is the difference between input-wacom and xf86-input-wacom?
input-wacom is a backport of the upstream Linux kernel driver. xf86-input-wacom is a userspace driver for the Xorg display server.
What are the system requirements? Is there special software I need to install to build the driver?
System and software requirements are covered in detail on the linuxwacom site. Please follow the links from the Basics page for more info.
