You will need to interface to C libraries like SDL.
Not necessarily any beyond the operating system libs. In fact, for a screensaver, you might want to use lower level calls. I don't know how they are made anymore, but in Windows 95 (showing my knowledge's age...) there were a few special screen saver functions you needed to implement for it to be recognized by the properties sheet.
I don't know about Ubuntu at all though.
