=== OLPC XO-1 touchpad mode selector ===
=== OLPC XO-1 touchpad mode selector ===
The original version of the [http://en.wikipedia.org/wiki/OLPC_XO-1 OLPC XO-1] laptop ("CL1") included a dual-mode touchpad manufactured by ALPS, where the center section could be used as a regular capacitive, finger-based mouse device, or the full width of the touchpad could be used as a resistive, tablet-style input device. Unfortunately, when used as a capactive, finger-based input device, the mouse cursor is often jumpy and difficult to use. This is due to hardware bugs, which the driver attempts to work around. However, some users report that when the mouse is used in the resistive mode, no such jumpiness is present.

Unfortunately, when used as a capactive, finger-based input device, the mouse cursor is often jumpy and difficult to use. This is due to hardware bugs, which the driver attempts to work around, with only limited success. However, some users report that when the mouse is used in the alternative resistive mode, no such jumpiness is present.
Sugar-0.92 adds a new icon to the devices section of the Sugar frame, which allows the user to switch between the two modes. By default, the laptop boots in the regular capacitive/finger mode, where the mouse can be manipulated ordinarily with a light touch of the finger. In this state, the icon appears as follows:
