The Displax SKIN products work on every Operating System (including Linux) as long it has a HID driver for multi-touch devices.
Similar to what happens with generic devices such as keyboards, mouses, USB cameras, if the Operating System has the necessary driver the SKIN will work.
Displax does not control the driver as it is part of the Operating System.
Note: The Displax Connect software is not a driver. It is the software that allows you to change the settings of the touch controller, and it is available for a limited number of Operating Systems (check here).
