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.
