kinda hijacking now , but saw this thread and reminded me of a problem i had while back with keyboard backlight ( still not solved cause wasn't bothered ) , then tried what Aravisian said in this topic ,and add command in ~.profile rather than .bashrc like i tried before and didn't work ...
now it's working perfectly !
as soon as i log in , i can toggle the keyboard light on/off with Shift+Scroll Lock like it's supose to work
PS : wanted to go back to old topic to post the solution for me , but topic closed ...
