TouchPanel.GetCapabilities() failing on Linux with an exception

This might be a special case... I have a chromebook which I installed Linux on (GalliumOS). It does not have a touchscreen (but some do).

My code works fine on Windows (OpenGL) and Android, but fails to run on the chromebook with the following exception:

Unhandled Exception:
System.EntryPointNotFoundException: GetSystemMetrics
at (wrapper managed-to-native) Microsoft.Xna.Framework.Input.Touch.TouchPanelCapabilities:GetSystemMetrics (int)

I have Mono 4.4.2 installed.

If I comment out the code which checks for / uses touchscreen, then the game runs fine on the chromebook.

Any suggestions on how I can solve this?

It would be great to support both touch and mouse input on these hybrid platforms, since I suspect there will be a lot more of them in the near future.

Thanks!
