Hello, I just recently installed ubuntu 16.04 on my Dell inspiron laptop and I can’t adjust the screen brightness using my function keys or the screen brightness applet in my panel. As I am new to this forum, I’m not sure what I need to include in my topic so please be gentle with me:slight_smile:. Just for information purposes, when I first switched over to ubuntu (from linux mint 18) I downloaded the 16.10 version first and my screen brightness could be adjusted using my function keys but I wanted a version that had long term support which caused me to do a clean install of 16.04. I have so far really enjoyed this system but can’t get a handle on this issue. Thanks to everyone who can assist me on this. I’ve included my system info below for information. Thanks to all again for any assistance.
