X Window System

X, or the X Window System, is the software that enables the XO's Sugar graphical user interface — windows, icons, and menus that you interact with using a pointer.

It is standard open source software provided with nearly all Linux distributions.

Restarting X

You can press Ctrl+Alt+Backspace to restart the X server without rebooting your XO.

Determining X version

In the Terminal Activity, type xdpyinfo and press Enter to display lots of information about the X Window System server on your laptop. Enter

 xdpyinfo | grep version

just to see the version.
