1. Create a chroot with X11:
   $ sudo sh ~/Downloads/crouton -r trusty -t x11
2. Enter the chroot:
   $ sudo enter-chroot -n trusty
3. Install i3:
   $ sudo apt-get install i3
4. Add exec i3 to ~/.xinitrc:
   $ echo "exec i3" > ~/.xinitrc
5. Launch i3 directly from the crosh shell:
   $ sudo enter-chroot xinit
6. Create an alias for starting in i3:
   add alias starti3='sudo enter-chroot -n trusty xinit' to your /home/chronos/user/.bashrc (chromeos)

• To change themes easily without installing to many other packages try: sudo apt-get install lxappearance
• For a proper Delete key, use bindsym $mod+BackSpace exec xdotool key Delete in your i3 config

Install crouton with XFCE and log in into XFCE with sudo startxfce4. Download i3: $ sudo apt-get install i3

Go to 'Session and Startup > Application Autostart' settings and '+ Add' a new command with the following field values:

• Name: i3
• Description: i3
• Command: /usr/bin/i3

Go to 'Session and Startup > Session', select the 'xfce-desktop' (amongst other xfce desktop related items -- all I have running is Xfsettingsd, Power Manager, and pulseaudio) and click 'Quit program'. Save session and restart chroot.

i3 should be up and running at this point.

If you haven't installed xiwi (or used it), you can follow the page below to install:

https://github.com/dnschneid/crouton/wiki/crouton-in-a-Chromium-OS-window-%28xiwi%29 (Note: To install xiwi target, e.g. sudo sh ~/Downloads/crouton.sh -t xiwi ...)

Then make sure we have i3 installed (additionally may need dmenu installed): sudo apt-get install i3 dmenu (note: actually i3 is already installed with the defaul xiwi target, but in case not, you can use the command above, follow the instructions above to install. )

1. Run i3 after entering in a crouton prompt: $ sudo enter-chroot $ XMETHOD=xiwi xinit /usr/bin/i3 (i3 would be happily running within xiwi under crouton)

2. Alternatively, create the following script to start i3 (modified based on startxfce4 etc), for which I named as starti3: `

  #!/bin/sh -e
  set -e
  APPLICATION="${0##*/}"
  
  USAGE="$APPLICATION [options]
  
  Wraps enter-chroot to start a i3 session.
  By default, it will log into the primary user on the first chroot found.
  
  Options are directly passed to enter-chroot; run enter-chroot to list them."
  
  exec sh -e "/usr/local/bin/enter-chroot" "$@" exec xinit /usr/bin/i3
`

• Currently, mod+1, 2, 3 ... doesn't work to switch workspace. For which I suspect chromebook system intercepts these keys as they are default shortcut key on chromebook ... don't know if there's a fix for it yet.
