No keyboard backlighting
Solution 1:
Open Terminal then type:
xset led
enter, and see the magical happen!
Solution 2:
Run this command in termial (ctrl+alt+t):
xmodmap -e 'add mod3 = Scroll_Lock'
However, you have to do that each time you open a session.
Therefore, I suggest you define this command as a startup application, so that it's run automatically upon login :)
