Comment 16 for bug 1121379

I have been testing with Ubuntu 13.04 and 3.9 rc kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline for a couple of weeks. The kernel drivers seems to work good. No error messages or bug traces appear in logs. evtest properly reports BTN_TOUCH events all the time.

But I think I now have stuck on this unity(?) bug also reported on other devices: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1099289 : Randomly, after some time using the touchscreen unity stops registering click events on tapping. Click with tap continues to work on some application parts (e.g. gnome-terminal tabs, or unity shutdown/logout dialog), but launcher, window titlebar and most applications' windows cannot be clicked with tapping. I have also tested with gnome-shell and kde from 13.04 repositories and seem to have similar issues. After some time (especially when doing fast subsequent taps on the screen or trying to drag a scrollbar or type on the on-screen keyboard) the main components of the desktop environment (panels, dialogs etc) do not accept a click with tapping, while the cursor continues to move properly at the tapped point and evtest properly reports BTN_TOUCH events.
