Brightness is reset to Maximum on every Restart
- by Bhargav
The brightness of my laptop is reset to Max on every restart. I tried the solution provided at this website but had no luck.
http://ubuntuguide.net/how-to-save-screen-brightness-settings-in-ubuntu-12-04-laptop/
This command
cat /sys/class/backlight/acpi_video0/max_brightness
Returns
cat: /sys/class/backlight/acpi_video0/max_brightness: No such file or directory
Then I go on to find that I don't have any folder named
acpi_video0
but a folder called
intel_backlight
Every time I increase or decrease the brightness using the Brightness Control Keys the "brightness" and the "actual_brightness" values get updated.
Is there any method I could follow to set the brightness to a fixed value on everyboot and vary it as and when I need it using the Brightness Control Keys.
