Issues in saving screen brightness

Question

I have Ubuntu 14.04LTS and a HP Pavilion dv6500. My computer doesn't remember the amount of brightness everytime I turn it on. Can somebody help me with some terminal command lines?

Thank you.

Answer 1

Please try this command:

echo 2500 | sudo tee /sys/class/backlight/intel_backlight/brightness

More info, please look in this thread How to change LCD brightness from command line (or via script)?

Answer 2

I use xbacklight to do this, which is simple and works perfectly.

Install it via terminal:

sudo apt-get install xbacklight

Then, I have a command set to run on startup:

xbacklight -set 0

(replacing 0 with whatever brightness level you'd like, 0 to 100)

Hope this helps!
