This is a long shot.
Clients like xdpyinfo use XF86VidModeGetModeLine() to get the
video timings, which include the current screen resolution.

I'm used to using this to see whether the resolution has been 
changed with <Ctrl><Alt><Num+> and <Ctrl><Alt><Num->.

That sort of resolution change leaves you with a virtual desktop,
so I don't know if it makes sense with a touch screen, but if so
XF86VidModeGetModeLine *doesn't* report the viewing window,
which makes the returned values less helpful.

XF86VidModeGetModeLine is specific to XFree86 (and derivatives)
and, more significantly, is a client call.
You would have to trace the code back to find a way to get the
equivalent information from within the server.
