I've been using Qubes on and off on a touchscreen device for a while, and while dom0 more or less supports touchscreens (although onl by emulating mouse events) guests only see mouse events. While that's fine for laptops it limits Qubes utility on the increasingly common 2 in 1 devices. While I understand that this is likely a fairly low priority, near as I can tell (as a non-programmer) it should be fairly simple to improve the situation by adding touchscreen messages to the Qubes GUI protocol. The idea would be that touchscreen events generated in an area of the screen rendering part of the guest would get passed directly through to the guest, similar to mouse events currently. That should allow for guests that support it (e.g. running an HVM fullscreen, multitouch supporting applications in a guest) to respond appropriately to inputs such as multitouch gestures and touch events on text boxes. Is this something that would be feasible to add?
