Change brightness of my laptop screen through command line

Unfortunately the Fn buttons for brightness don’t work with Lubuntu and my Acer laptop. Luckily, there is a command line solution for that:

xrandr --output LVDS1 --brightness 0.8

I’m pretty sure you can figure out that 0.8 means 80% right? Rest is simple 😀

I know that this is not a remarkable blog post but next time I’ll be sitting in the darkness blinded by my screen’s too strong brightness I’ll know exactly where to look for the command that changes it 🙂

Have a nice weekend!
