Sugar is the core of the OLPC Human Interface. Its goal is to turn the Laptop into a fun, easy to use, social experience that promotes sharing and learning.

Sugar running on Fedora


Getting Sugar

Sugar is available:

on the XO laptop
If you have an XO-1, it's running Sugar. Read Upgrading the XO to update to the latest version.
as OS images
You can install or upgrade an XO to a new OS image. You can also run a Sugar image using emulation on almost any operating system, including Windows.
as Live CDs
You can download a LiveCD .iso file and burn it to a CD, and then boot and run it on almost any x86 PC, including x86 Macintosh.
as packages for other Linux distributions
You can install Sugar from packages on other Linux distributions (Fedora, Debian, Ubuntu, etc.) using yum or apt-get, and run Sugar as an alternative UI.
as runnable source code for developers on Linux
Developers on Linux can install from the latest source code using Sugar with sugar-jhbuild.

Once you get Sugar running, take a picture of your desktop or laptop running Sugar, and leave a thumbnail and note in the relevant Talk page (the "discussion" tab) about what build you used and how it worked.

Getting started

You can explore the Sugar interface in our Getting Started guide. There are other Getting started resources.

Note the "Frame key" Key frame.jpg at the top-right corner of your keyboard, which toggles the presence of the Frame on and off the screen. (The Frame is the black border around the screen that holds the activity taskbar, clipboard, buddy list, etc.)

You can restart Sugar by pressing the Ctrl-Alt-Erase keys simultaneously.


Developers, once you've installed Sugar, you can go on to develop for the environment.
