OLPC

  Information on this page is specific to the OLPC XO laptop.

OLPC (One Laptop per Child) is a non-profit association developing the low-cost laptop—the "XO Laptop". The Sugar project was originally started in support of the XO laptop, which has a number of features specific to Sugar, most notably, a number of keys dedicated to the interface.

Using Sugar on an XO

This section tries to capture a number of OLPC-specific hints to using Sugar.

Keyboard shortcuts

The XO laptop has dedicated keys that can be used in navigating the Sugar interface. Please see the keyboard shortcuts page in the OLPC wiki.

USB Ethernet adapters

See the USB Ethernet Adapters page for a list of options.

Click

To “click”, press once on the left-hand touchpad button—the button with the × symbol at the front of the touchpad.

Getting connected

Please refer to the Wi-Fi Connectivity page in the OLPC wiki for details about how to connect an OLPC XO laptop to the Internet.

Random Notes

Wireless Loss

XO machines may experience problems with Access Points not showing in network neighbourhood, or taking a long time to be shown, especially as the number of XO laptops in a room increases. This is now fixed: On XO-4 (8787), the problem does not occur, on OLPC OS 11.3.1 and earlier the problem should not occur, and the solution is to upgrade to 13.2.1.

On XO-1.5 machines, an aggressive suspend and resume may also cause wifi to stop working. The solution is to go to Control Panel, Power, and uncheck powersaving.

Mesh Networking Deprecated

XO-1.5's do not have Mesh networking support, so they use 802.11 Ad-hoc
networks.  XO-1's default to Mesh networks at the moment for compatibility,
because that is what they historically have done.
Once an XO-1.5 starts an Ad-hoc network, the XO-1's will spot that network
within a minute or two, and use the same Mayan numeral as the XO-1.5 to
indicate its presence.  If all the XOs leave an Ad-hoc network it
disappears; but Network Manager/Sugar cache its presence for a while in case
a scan accidentally missed a network.
When an XO-1 sees an Ad-hoc networks they are all filled in as "occupied",
because an XO-1 does not show the unfilled variants to allow an XO-1 to
start them.
This behavior has been around since OLPC build 10.1.3 (860) & Sugar 0.90,
and is described at Features/Ad_hoc_Networking
I believe XO-1's can be adjusted to default to Ad-hoc as well if desired
