Keyboard backlight fix
Source for this information can be found here
The link has a file called kb-light.py. I set up this file in /usr/local/bin.
I then opened my i3config file and added the following:
bindsym XF86KbdBrightnessUp exec python /usr/local/bin/kb-light.py + bindsym XF86KbdBrightnessDown exec python /usr/local/bin/kb-light.py -
And now when I press the keyboard brightness up and down key, the keyboard lights change as expected.
Screen brightness fix
For this I wanted to use xbacklight. The problem I got was that when I tried
xbacklight -inc 10
I got the error "No outputs have backlight propery".
To fix this, I installed the intel driver
sudo pacman -S xf86-video-intel
And after rebooting it worked well. So to set up the keyboard keys for screen brightness, I added this to my i3 config file:
bindsym XF86MonBrightnessUp exec xbacklight -inc 10 # increase screen brightness bindsym XF86MonBrightnessDown exec xbacklight -dec 10 # decrease screen brightness
Media Keys Usage Fix
For this, I first had to install pulseaudio.
sudo pacman -S pulseaudio
Then I added this to my i3 config files:
bindsym XF86AudioRaiseVolume exec --no-startup-id pactl set-sink-volume 0 +5% #increase sound volume bindsym XF86AudioLowerVolume exec --no-startup-id pactl set-sink-volume 0 -5% #decrease sound volume bindsym XF86AudioMute exec --no-startup-id pactl set-sink-mute 0 toggle # mute sound
Now audio can be increased / decreased using my media keys.
