Comment 6 for bug 133430

The problem with having xrandr or the driver hardcode the policy is that it wouldn't work properly with other wacom hardware (not all wacom devices are built into screens, and it's unclear what to do when there are multiple displays, and the user rotates one of them...).

Perhaps some sort of event notification thing would make more sense. xrandr could generate events like acpi and hotplug do. Then the wacom rotation script could be registered with an event notification daemon, just like the gnome power management stuff... That would make it easier to write quick and dirty scripts that "do the right thing", and let the gnome people try out a few GUIs (and maybe a graphical calibration tool...) until they're happy with it...
