Cody, the current version of my script works only with one graphical adapter (its brightness file is named /sys/class/backlight/acpi_video0/brightness). You can customize this value in my script at row 16 BRIGHTNESS_CONTROL=/sys/class/backlight/acpi_video0/brightness to path which is *correct* for your hardware.
Correct path may be determined by the following steps: 1. List all paths with brightness file in /sys/class/backlight dir with the command ls /sys/class/backlight/*/brightness example: /sys/class/backlight/acpi_video0/brightness /sys/class/backlight/acpi_video1/brightness 2a. Read values of brightness from files with the command: cat /sys/class/backlight/*/brightness example: 3 8 2b. Change backlight level with hardware keys (Fn+...) and read again: cat /sys/class/backlight/*/brightness example: 4 8 2c. The *correct* path to brightness control file corresponds to the changed value. example: /sys/class/backlight/acpi_video0/brightness # first value changed, so first file 3. Try to write brightness level manually to *correct* brightness file: sudo su echo 3 > /sys/class/backlight/acpi_video0/brightness # example on my hardware 4. Change BRIGHTNESS_CONTROL variable to the *correct* path in /etc/init.d/brightness with the command sudo gedit /etc/init.d/brightness I'll update my script soon to do all steps automatically. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1270579 Title: Ubuntu should have an upstart job for saving/restoring backlight level on laptops To manage notifications about this bug go to: https://bugs.launchpad.net/elementaryos/+bug/1270579/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
