When I try running xbacklight -inc 10 I get an error message "No outputs have backlight property"
I've searched the issue and found several answers usually suggesting some form of modifying /etc/X11/xorg.conf which I have previously done on this laptop to get backlight working in the first place
# /etc/X11/xorg.conf
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "Backlight" "intel_backlight"
EndSection
the unique thing about my situation this time around, is xbacklight was working fine until after I installed the intel graphics drivers through the oibaf PPA
sudo add-apt-repository --remove ppa:oibaf/graphics-drivers
sudo apt update
sudo apt install xserver-xorg-video-intel
after running the above commands and rebooting I found my mouse and keyboard didn't work so I had to reinstall the drivers by running
sudo apt install xserver-xorg-input-all
after all this the game I was trying to play still didn't work so I removed the PPA and uninstalled xserver-xorg-input-all
I couldn't scroll with my Touchpad after this as well so I had to reinstall that package as well(sudo apt install xserver-xorg-input-synaptics).
This is why I suspect the xbacklight issue isn't a problem with the config, but instead when I was removing the drivers I removed xbacklight drivers. Is there another package I need to install to restore xbacklight?
