      Hello everyone,

      I've got pfSense running on an old laptop, now I'm having this issue that the backlight of the display always stays on.
      I installed and enrollen green_saver successfully, no more text is being displayed on the screen, but that's the least of the power-eaters. Is there any way to switch off the backlight?

      Thanks in advance,
      T

      P.S.: sorry if this is in the wrong section.

        There was a thread about this previously. If I recall there were some additional modules required. Have a look through the forum if you haven't already.

          Hello Stephenw and thanks for your answer.

          After a while of playing around I seem to have found the issue, it now disables the backlight when the lid closes, SUCCES! :D
          I don't know which command actually did it, so I'll post them all:
          vidcontrol -t 1 < /dev/console
          vidcontrol -t 1 < /dev/ttyv0
          vidcontrol -s 1 < /dev/ttyv0

          So a combination of green_saver.ko module and one of the above commands helped me disable the backlight.

          Thanks for your support,
          Cheers

          EDIT:
          Or not … I just pushed on the screen and the backlight disabled itself, so either the commands are working as intented or the switches are somewhat broken...
          I just put an heavy object on the screen and it's disabled, works anyway.
