Wacom Tablets on Dualhead
May 9 2011
In the past, defining the screen area you want to map to the tablet was a matter of defining the active rectangle with bottomx, bottomy, topx and topy per device using xsetwacom.
In Fedora 15 you only need to set the target screen ID with MapToOutput. You can learn the display ID by running xrandr. The tablet devices you get by running xsetwacom list devices. For my setup I use:
xsetwacom set "Wacom Cintiq 21UX2 stylus" MapToOutput DVI-I-2
xsetwacom set "Wacom Cintiq 21UX2 eraser" MapToOutput DVI-I-2
Hope this helps anyone struggling. This was the TL;DR version, Wacom project documentation is pretty useful.
