I would like turn on/turn off some of my leds running a command on linux.

I use Ubuntu 12.04 LTS.

I tried

xset led named "Scroll Lock"
xset led named "Num Lock"
xset led 2             (this is the number of Scroll Lock as `xset q` says)
xset led 1

but nothing works.

Tried

setleds +num
setleds +scroll

but I got a error message saying Error reading the current settings of flags. Maybe you're not on the console? (I was in a terminal).

So, how can I perform this?
