Workspace output multiple values

I'm trying to bind workspace 5 to output VGA1 and DP1 too. (I have display port at home and vga at work)

I currently have this, but the second entry obviously overwrites the first one so when I plugin the VGA monitor it gets workspace 2.

workspace 5 output VGA1
workspace 5 output DP1

What would be the best way to do it?

There is no builtin feature to do this. But with some scripting it should not be too difficult.

First set a variable in your configuration file for the output(s) and reference it in your workspace definitions:

set $OUTPUT1 LVDS
set $OUTPUT2 VGA1

workspace 1 output $OUTPUT1
workspace 5 output $OUTPUT2

Then you need a script that changes the variable definitions for you and reloads the configuration

#!/bin/bash
OUT2=$(xrandr | awk '/(VGA1|DP1)/ connected/{print $1}')
OUT2=${OUT2:-LVDS}
sed 's/^set\s\s*$OUTPUT2\s.*/set $OUTPUT2 '$OUT2'/' -i "${HOME}/.i3/config"
i3-msg reload

Now you can set a keybinding for this script.


WARNING: UNTESTED

You could even run this script directly from your configuration file

exec --no-startup-id /path/to/outputcheck.sh

As exec statements are not executed when reloading the configuration it should not lead to an endless loop. I am assuming that the statements are also only run after i3 has fully parsed the configuration file (for the first time) and reloading can thus be done without risk, but I am not sure.
