Dextrose - Deployments' XO Operating System

Dextrose is a Sugar distribution for the XO-1 and XO-1.5. It is being developed jointly by Activity Central, Paraguay Educa, Plan Ceibal and Sugar Labs, in collaboration with members of the OLPC and Sugar community.

The focus of this build is stability and usability in a classroom environment. While there wasn't much time for new development, we've merged a few features contributed by other deployments and freelance contributors.

New features in this release

Installation

XO-1

  • First, ensure that your laptop is unlocked.
  • Download osNNNpy.img and osNNNpy.crc to the root directory of a USB stick
  • Drop to the "ok" prompt by pressing ESC repetedly during boot
  • Type the command: copy-nand u:\osNNNpy.img followed by ENTER
  • During the next reboot, keep the charger connected to allow OFW to self-update

Also check these detailed instructions.

XO-1.5

Using this build

A few customizations make this image somewhat deployment-specific:

  • Limited language support: to save space, we've included only English and Spanish translations.
  • Image signed with the Paraguay deployment keys. Laptops from other regions need to be unlocked in order to accept this image.
  • The software update control panel icon checks for new activities on our wiki rather than on laptop.org.
  • The Browse home page contains the Paraguay Educa logo and a few links to our website.

We may find the time to release slightly modified images to meet the needs of other OLPC deployments interested in upgrading to Sugar 0.88.

More importantly, we're happy to help other deployments produce their own OS images independently of us, thus exploiting the Freedom #1 provided by Free Software.
