I'm running Ubuntu 13.04 on my Samsung RV520 with Nvidia GT520M but it looks like my screen's brightness is set to a value close the minimum! Even though I can see the brightness bar increase or decrease by pressing Fn up or Fn down, or by trying to manually adjust it, it never really changes...

There is command like xbacklight, but not all displays resp. drivers of graphics cards work together with this command. As I see in manpages xbacklight probably is referring more to intel-chipsets. But if your machine has an intel-processor with hybrid-chipset of nvidia like GT 520M ( mine here is GT 540M ) - this should work to use xbacklight cautiously as command like explained here at top of :
