Bug description:
My laptop has a touchscreen. It works fine in 14.04 until I plug in an
external monitor. When using an external monitor, input from the
touchscreen is remapped so that the touchscreen provides input to both
monitors. The result is that there is no longer a 1:1 correspondence
between moving your finger and the cursor. This is confusing and
difficult to use.
A touchscreen is a direct input device (vs an indirect one like a
mouse/touchpad); input from the touchscreen should be bound to the
physical display that it's attached to.
To reproduce:
1) On a computer with a touchscreen, use the touchscreen to move a window
around, including to the edges of the screen. Note that the window moves
exactly with your finger.
2) Plug in an external monitor
3) Try the same actions as in step 1
Expected results:
The touchscreen continues to operate as in step 1, allowing you to manipulate
items on the display that contains the touchscreen. The touchscreen does not
interact with windows, etc on the external monitor
Actual results:
The touchscreen is remapped across both displays. The result is that touch
events no longer happen 'under the finger'. Assuming the two displays are the
same size and resolution, moving your finger 1cm will cause the window or other
objects to move 2cm onscreen. It becomes impossible to use the touchscreen to
interact with widgets (menus, buttons, etc).
This is described in couple places:
