How to use

I3 Config

In order for the script to get workspaces owned by each monitor, we need to map your workspace names to numbers in the i3 config file

It will not have any effect on your current workspace names

Normally, we use follow lines to assign our workspace name

set $ws1 "Terminal"
set $ws2 "Chromium"

Now, we need to write lines in these way
Simply add number: in front of your workspace name

set $ws1 "1:Terminal"
set $ws2 "2:Chromium"

Also, you should add strip_workspace_number yes in the bar block

bar {
      strip_workspace_number yes
      ...
}

Config the script

Open the script you will find the class name Config, put your command line for setting background in the variable cmd_set_background
Class Config is at line 6
Example :

class Config:
    def __init__(self) -> None:
        # You need to put the command or script in <cmd_set_background>
        self.cmd_set_background = '/home/novel2430/.config/i3/background.sh'

Usage

Simply run the script by

python monitor-selector.py

or (need chmod +x monitor-selector.py)

monitor-selector.py

You can set key binding to this script

TODO

• Make no chages to the user's i3 config file
• Custom resolution
