X2X

X2X is a great program for users who have two computers and monitors, or a monitor and a laptop, and want to share mouse and keyboard between the two monitors. You have to be using X on both machines. In my case, I have Ubuntu Gustsy on both. To install X2X, on one workstation 1 do:

sudo apt-get install x2x

And on the laptop or second machine do:

sudo apt-get install x2x openssh-server

Now, on worksation 1, just do the following in the command line.
