- Change the value in /sys/class/backlight/acpi_video0/brightness each time OS boots.
- Create /etc/rc.d/rc.local (Fedora no longer ships it since release 16).
- Edit the file so that it looks like this.
- Make /etc/rc.d/rc.local executable.
- Add kernel parameter (to be investigated).
$ cat /etc/rc.d/rc.local
#!/bin/bash
echo 7 > /sys/class/backlight/acpi_video0/brightness
$ sudo chmod a+x /etc/rc.d/rc.local
