How can I fix a bug that wouldn't let me turn the backlight on after it turns off automatically when I close the lid or when powersave settings kick in?
I also can't adjust the brightness of the screen through the Fn + Left/Right Arrow button combination, how can I make this work?
And one last thing, when I try to follow some of the fixes that are being suggested in forums, like editing the etc/x11/xorg.conf by using the terminal command sudo gedit, the file that I'm supposed to edit is totally blank. And when I look at the folder I didn't see a file "xorg.conf" but I saw "xorg.conf.failsafe" I tried creating a xorg.conf but I can't save the file. What shall I do in this kind of scenario, just in case the solution for my first 2 question requires sudo gedit? Thanks!
