Already posted in Community, but got locked and moved, and got lost, sorry.

Here's the issue:

I'm using Ubuntu in a Sony Vaio SVF15A17CLB, which has a backlit keyboard, but it's not turned on by the System by default, so, every time I want to turn it on I have to manually change the value in: /sys/devices/platform/sony-laptop/kbd_backlight from -1 to 1 with sudo vi

But that resets every time I restart the computer.

Is it a setting somewhere else handling that? Can I make it permanent?

  • Have you tried adding an echo 1 >> /sys/devices/platform/sony-laptop/kbd_backlight line to /etc/rc.local (above exit 0). – dsstorefile1 May 1 '18 at 23:00
  • That looks like the answer. But now I have the problem that I don't have a rc.local file – Mauricio Machado May 2 '18 at 13:16
  • Just added the file and boom! like a charm. Thanks! One detail, though, changed the >> operator to a >, since I want to write, not append. – Mauricio Machado May 2 '18 at 13:44
  • You're welcome! I'm glad things worked out for you. – dsstorefile1 May 2 '18 at 19:11
