wacom one tablet linux dual monitor setup
View gist:ef00d7667b2ba221f444b4aea35749c8
### Requirements ###
* X Server 1.8 or later
* xf86-input-wacom-0.10.9 or later
## MapToOutput ##
Tip: The '''MapToOutput''' [[xsetwacom]] parameter requires at least xf86-input-wacom-0.11.99.1 to work with the NVIDIA binary driver. See [[Coordinate Transformation Matrix|Dual-and-Multi-Monitor-Set-Up#coordinate-transformation-matrix|]] instead.
The wacom driver does not support multi-monitor setups directly - handling of such setups is handled by the X Server. [[xsetwacom]] does however provide a parameter to easily map a tablet to a screen
