x2x is an utility to share the Keyboard and Mouse between more than one computer. So you can configure your Desktop PC with its regular Keyboard and Mouse to write and move the pointer cursor on the XO. This is very useful to me, so I'm going to explain here what I did (on Fedora 17) to set it up.

  • Download the source
git clone git://
  • Install required dependencies to build it
sudo yum install libXtst-devel.x86_64
  • Configure and compile it
cd x2x
  • Go to the XO and connect to your Desktop PC via SSH and run x2x
ssh -X yourusername@yourdesktophostname / yourdesktopip
cd x2x
DISPLAY=:0 ./x2x -to `echo $DISPLAY` -west

Now you can move the mouse up to the left side of the screen and if you keep moving it in that direction the cursor will appear in the XO screen. Once you have focus on the XO when you type on the Desktop Keyboard you will be typing in the XO. It's magic!

NOTE: I used -west because I have my XO at the left of my Desktop PC
