I would like turn on/turn off some of my leds running a command on linux.
I use Ubuntu 12.04 LTS.
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.
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?
