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.
 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.
 Running X applications
You can install and run some graphic Linux software that displays using X. You can start these X applications from Terminal Activity (note they do not work from the console as they need at least DISPLAY and XAUTHORITY environment variables).
Unlike Sugar Activities
- X programs appear as a gray circle icon in The Frame.
- Sharing and collaboration don't work
- Your work doesn't appear in the Journal, you have to explicitly navigate the file system to save and open files.
