I tested again on Saucy, after having Raring running for some time and
afater updating Saucy to the newest state (still with X staging PPA) and
now touch operation seems to be stable. I did a lot of touch movements,
both clicks and drags and the touch screen keeps working.

A little hint to make touch operation of the Ubuntu desktop easier is to
turn off the overlay scrollbars. The classic scrollbars are much easier
to operate via finger-based touch screen.

Command to turn off overlay scrollbars

gsettings set com.canonical.desktop.interface scrollbar-mode normal

and to get overlay scrollbars back

gsettings reset com.canonical.desktop.interface scrollbar-mode

These changes get active immediately, even on already running
applications. The settings are also persistent (I tested by logging out
and in again).
