Change screen size in knoppix

[SomeProgr]

Im new to linux and i just finished installing knoppix 3.4. How do I change the screen resolution from its default (1024x768) to a different size (1280x1024)? I also may need to change the refresh rate so how would I do that? Thanks.

Did you get the little icon on the taskbar that looks like a picture frame? Close to the clock.
