OLPC XO-1
From Wikinomial
When the OLPC XO-1's software is upgraded, it installs a fresh image rather than upgrading individual components. Here are my notes on how to restore my settings.
* Power Management
* In the control panel in the center of the apps page, uncheck the power management options
* To prevent suspend when closing the lid, sudo touch /etc/ohm/inhibit-suspend
* run "init 3" to disable all of the GUI sugar stuff
* when I run pandora, sometimes it stutters because sugar is doing stuff
* turn off the screen backlight:
* echo "0" > /sys/class/backlight/dcon-bl/brightness
* turn it back on by writing "15" to it
