The touchscreen is useless at the moment, all I can do is move the mouse on the screen, but it won't handle clicks.
I also tried to install and configure easystroke, which will recognize 1-finger patterns, but 2+ fingers actions are not recognized.
If you had more success than me on touchscreen configuration, please share your recipe, thank you!
Maybe something with your desktop environment (KDE, Gnome) is the issue. I use Gnome 3 and, apart from the suspend issue for the touchsceen, both features work out of the box.
