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.

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.

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.

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 Activities software update uses http://wiki.laptop.org/go/Activities/G1G1/ preinstalled activity list for 11.3.0 XO-1.5: http://dev.laptop.org/git/projects/olpc-os-builder/tree/examples/f14-xo1.5.ini XSCE on XO-4
