Enable a Key

Hi team,

Print Screen key is disabled in my machine. How can i enable it?? How do i do that via command line?? Or tell me in GUI.. Am using Linux Fedora 14 OS.

Not disabled as much as unused; print-screen handling is a software thing, not part of the OS, not built in.

Some linux WMs responds to print-screen. Which do you use?

Am not sure about it..
