I am using Ubuntu 16.04 in dual boot settings on my Legion Y520. However, I am unable to set/change brightness of the screen and it remains 1005.
I have tried all the available solutions on the forums but to no avail.
When I enter the command
on command prompt, it doesn't output anything.
I also tried the solution given by here but that also didn't work.
Full brightness is really hurting my eyes so please help me.

What you tried only works for intel cards.
I think your computer is not the case.
Try to read the following article:
When you enter the command
what is the output?
If there is no output, it means the folder is empty.
Then you cannot follow the steps in the solution you found.
