Unless you are running this command from a virtual terminal (tty0-ttyXXXX), chances are it wont work. setleds uses an ioctl (KDGETLED)on the file descriptor for stdin, and whatever is driving stdin responds as best it can. The tty devices know how to respond to KDGETLED, most other things ptys, pts, etc will return the above error (invalid argument). Cheers, Malcolm V.
