I have a problem with my 530U4E/540U4E Samsung Ultrabook Backlight settings; the system doesn't seem detect the change in brightness settings. To fix it I tried the "Intel backlight Fix" because my hardware is mainly Intel based.
Heres a list of my ultrabook's hardware Specifications followed by how I tried to implement the following fix.

My first attempt I used the
sudo command like in this article. I was told that using
sudo could be bad so I tried what @zanna recommended to use
sudo -i instead, but still doesn't work, maybe I did it wrong?
I tried it through
nano and a
No metadata error message came up but nothing changed. Is there anything else I can try?
If you know one id be happy to give it a shot, thank you in advance.
I Apologize in advance as I'm still learning to use the terminal, I'm a quick learner so no worries!
Edit: Just checked to see if I needed a specific from Intel if they had one and I found this https://01.org/ (for linux specific Drivers) though Ubuntu comes with this by default so it might not be the driver like some post suggest?
Update: Just tried another fix in this link This one doesn't work either, same metadata error appeared, like in the first one. I'll see if I can find more I can try and I'll post an update if I find something.
