# Add the setup for a simple i3 configuration. It´s pretty easy to use and
# functions super well. Very easy to get going and does not need a whole lot of
# work to change things around. Good alternative to DWM and so lightweight that
# it doesn´t even matter if both are installed!!

# TBD: Automate getting the brightness keys to work.

# User is already part of the video group. Just need to configure udev rules.
#
# Get the folder name from here: `ls /sys/class/backlight/`
#
# That is your <DEVICE> for the following lines, which go here: /etc/udev/rules.d/backlight.rules
# ACTION=="add", SUBSYSTEM=="backlight", KERNEL=="<DEVICE>", RUN+="/bin/chgrp video /sys/class/backlight/%k/brightness"
# ACTION=="add", SUBSYSTEM=="backlight", KERNEL=="<DEVICE>", RUN+="/bin/chmod g+w /sys/class/backlight/%k/brightness"
#
# So, for example:
# [18:12:20 root@device ~]# cat /etc/udev/rules.d/backlight.rules
# ACTION=="add", SUBSYSTEM=="backlight", KERNEL=="intel_backlight", RUN+="/bin/chgrp video /sys/class/backlight/%k/brightness"
# ACTION=="add", SUBSYSTEM=="backlight", KERNEL=="intel_backlight", RUN+="/bin/chmod g+w /sys/class/backlight/%k/brightness"
# [18:12:21 root@device ~]#
#
# It then required a reboot. Doing the commands below was not enough.
#
# # sudo udevadm control --reload-rules
# # sudo udevadm trigger
