Can't change brightness

[Ally9]

I noticed about a month ago that I can no longer change the brightness on my laptop, through the buttons or on the screen. I tried to google how to fix it but couldn't really understand it

Updating didn't help. I uninstalled the driver but I'm not sure what to reinstall since there are many things in the link you gave me
