systemctl reboot

Troubleshooting

If your distribution does not packages i3-gaps (check by running sudo apt policy i3-gaps) you can either:

Install i3-gaps from source.
Install i3 (without gaps) and remove the gaps settings from the config file.
- sudo apt install i3-wm i3status i3lock
- cat ~/.config/i3/config-no-gaps.bak > ~/.config/i3/config

Once in an i3 super+enter to open a terminal, see the shortcuts here.

Notes

home/.homemade is a directory for my custom resources, scrips, etc.
Some scrips from home/.homemade/bin might not work properly.
To set up the latest color scheme run nohup set-global-color-scheme $HOME/.config/xresources/color-schemes/x-default &>/dev/null && exit.
