I got nice laptop with a touchscreen (HP Envy TM m7). It came pre-installed with Windows 8 and I promptly put Ubuntu on it. Due to some issues, 13.04 wouldn't work so I went with the 12.04.02 LTS instead.
The touchscreen worked out of the box when it comes to clicking, but I wonder if there is a way to add more tablet-like gestures such as 2-finger pinch zooming, or scrolling with a one-finger swipe, or cycling through open applications by swiping from the screen edge etc.
Google results are in most cases only concerned with touchpad gestures.
Here is the weird thing: Two-finger gestures work on the touchpad (e.g. the two-finger scrolling) and can be changed in the "Mouse and Touchpad" panel. Three-finger gestures such as pinch to maximize or Four-finger tap to open dash do only work on the touchscreen.
What I cannot seem to configure is two-finger scrolling on the touchscreen, as there is in general no settings panel for the touchscreen.
