  • It does send a keycode
  • How do you change the backlight brightness from a program (rather than the keyboard buttons)?
  • How is the brightness level being changed? Some embedded EC? OF? Do we get a userspace signal/event when the user changes it?
  • DPMS seems not to work. "sleep 1 && xset dpms force off" does nothing.
