I am running a jenkins instance on a headless ubuntu server. For some of the GUI tests, I get the following error 

org.assertj.swing.exception.ActionFailedException: The component to click is out of the boundaries of the screen

How can I set my screen resolution?

If you are using xvfb this might be what you are looking for:

xvfb-run --auto-servernum --server-args "-screen 0 1024x768x24" ant test

This will adjust the virtual screen size. Replace "ant test" with your own command.
