Hi everyone. I'm using Xubuntu 12.04.1 (but the same happens on Xubuntu 12.10 alpha) on a Asus T91MT Convertible netbook (i.e. with a propietary touchscreen). Everything is nice and responsive, but the window bars are unresponsive to the touchscreen: no clicking "X" to close, no moving them around or rolling them up, no resizing. All of this works, if done with the touchpad.
PS: Found this link:
...but i can't get much more from it.
