Move all workspaces to one monitror and back

It sounds to me like you want to assign a number of workspaces to your external monitor. See http://i3wm.org/docs/userguide.html#w.... When the output is unavailable, workspaces will be moved to the first available monitor (your laptop monitor) and when it becomes available again, workspaces will be moved there again.

Sounds like the original poster wants xmonad behavior where whichever monitor is focused, by pressing mod-# that workspace would jump to the focused monitor (if not there already). The current behavior is to put the focus on the monitor to which the workspace is assigned and jump to it there.

I didn't have any luck unplugging my monitor, disabling the external display then re-enabling it. Once a monitor is unplugged it seems all existing workspaces just get moved to whichever one is left (the laptop display).

The documentation, though mentions, a command (that could likely be bound to a key) which will move the workspace to another monitor, that works like this:

$ i3-msg move workspace to output [xrandr output name]

or

$ i3-msg move workspace to output [left|right|up|down]

so if you have two monitors... bind a key to left and bind a key to right and you can just toggle a display between them:

bindsym $mod+v exec i3-msg move workspace to output left

bindsym $mod+b exec i3-msg move workspace to output right

I created a script that I run before I unplug my monitor that allows me to 'save' the workspace states... I can then run it again with 'restore' when I plug the monitor back in and it will restore the workspaces to where they were before: i3plug.py

I hope this helps you. The following will turn off your monitors when unplugging and turn them on again when you plug it in. Turning the monitor off will force i3 to put all workspaces on the remaining monitor. Turning it on again will simply create a new blank workspace, I'm working on a restore-script but wanted to share the progress so far.

Following Ikraav's comment, we will be using udev for this.

First check if unplugging your monitor actually results in an event. Look for (drm) in the output of the following command:

  #: udevadm monitor --property

Then create a new udev rule, on Ubuntu e.g. in /etc/udev/rules.d/80-monitor-hotplug.rules

  ACTION=="change", SUBSYSTEM=="drm", RUN+="/root/monitor-hotplug.sh"

Then create your script in /root/monitor-hotplug.sh. You will have to replace the adapters with the ones relevant to you, and of course your username.

  #!/bin/sh
  # Read the status of the relevant graphics adapter
  read STATUS < /sys/class/drm/card0-DVI-D-1/status
  export DISPLAY=:0
  export XAUTHORITY=/home/vk/.Xauthority
  if [ "$STATUS" = "connected" ]; then
    xrandr --output DVI-D-1 --above LVDS-1 --auto --screen 0
  else
    xrandr --output DVI-D-1 --off --screen 0
  fi

And that is it. Still todo:

• Not sure yet how to handle XAUTHORITY for multiple users
• Restore workspaces when plugging back in. The workspace setup could e.g. be cached in a file in the homedir and then restored.
