[[Category:Feature|Touchpad section for Control Panel]]
</noinclude>
== Summary ==
This is an enhancement to the Control Panel that enables the section of mode for the Touchpad on the OLPC XO-1 CL1 laptop.
== Owner ==
* Name: [[User:Walter|Walter Bender]]
* Email: <walter at sugarlabs dot org>
== Current status ==
* Targeted release: (0.88x)
* Last updated: (19 May 2010)
* Percentage of completion: 95% (awaiting review; awaiting corresponding patch to olpc-utils)
This feature is being tracked in [http://dev.sugarlabs.org/ticket/2006 Ticket 2006].
== Benefit to Sugar ==
There are approximately 1000000 XO-1 CL1 deployed. Many have very flaky capacitive touchpads, which makes the Sugar experience very tedious. This patch would enable users to switch to the resistive touchpad and in theory have a better experience. (Tests are being conducted in Peru, Paraguay, and Nigeria.)
== Scope ==
To implement this feature:
* two new icons were added to share/icons/sugar/scalable/devices:
::capacitive.svg and resistive.svg
* a new section was added to sugar/extensions/cpsection
:: touchpad
* a new icon was added to sugar/data/icons
::module_touchpad.svg
We still need a script to be added to olpc-utils that is executed at boot time to: (1) change the mode of
/sys/devices/platform/i8042/serio1/ptmode to 666; and (2) write a 1 to that node if a flag file exists ("/home/olpc/.olpc-pentablet-mode").
== How To Test ==
{{:{{PAGENAME}}/Testing}}
== User Experience ==
Anyone who has used Sugar in a high-humidity or dust environment on the CL1 hardware has probably experienced the jumping cursor due to the malfunctioning capacitive touchpad. Using a stylus is a different experience, but more predictable and robust in these situations.
Note that the section only will appear on CL1 hardware. There is no change to user experience with Sugar on other hardware platforms, including the more recent versions of the XO-1.0.
== Dependencies ==
No additional dependencies are required to implement this feature.
== Contingency Plan ==
None necessary, revert to previous release behavior.
== Documentation ==
== Release Notes ==

''The Sugar Release Notes inform end-users about what is new in the release. An Example is [[0.84/Notes]]. The release notes also help users know how to deal with platform changes such as ABIs/APIs, configuration or data file formats, or upgrade concerns. If there are any such changes involved in this feature, indicate them here. You can also link to upstream documentation if it satisfies this need. This information forms the basis of the release notes edited by the release team and shipped with the release.''
