I have a problem similar to this:

I'm using a Lenovo s10-3t with Xubuntu 12.04, and everything is great except that xfwm doesn't respond to touch screen taps. The only response I get is if I hold down the alt key and move the window, but even then I can only move it using the window border..?

Does anyone have a tip on how I can resolve this, or at least proceed to figure out what the problem is? Apparently it doesn't happen on all touch screens.
