Brightness function keys won't work (SOLVED)
« on: November 26, 2017, 07:43:55 am »
So I just installed OS 8 and things are going very well... but the brightness function will not work. I have tried the fn keys and the power management settings but no change. Any thoughts? Thanks.

Code: [Select]
xbacklight -set 70Where the number is %of maximum brightness.

Humm...
Looking at the output you've posted, two things are sticking-out: 1) you are running the 4.8.0-53-generic kernel and 2) on your graphics card section you have FAILED: nouveau...
Getting the updates with
Code: [Select]
sudo apt-get update
Code: [Select]
sudo apt-get upgradewill get you to the current kernel.
Then, look to install the needed NVIDIA driver for your graphics card.

Hope this works. I don't really know how to find the correct driver for your card, but I'm sure that, if you have trouble, someone else here will be able to help.

I'm on PM7 and I adjust brightness using the slider in power management, it works just fine and it sticks after rebooting. As for the function keys, they don't work for me either. These key combinations have to be set to their function and I've never really cared enough to do that.

Yup I think you are on to something. Poking around last night I found the additional drivers, but ever time I try to change them to NVIDIA they revert. I am updating now. Thanks for the sugesstions...we shall see.

You could check section 1.2 on the following link,

EDIT: There are some nice tips and tricks on that link but, do not hold the kernel updates as it is suggested there.
