How can I display the waybar on only one of the monitors?

[steveoriol]

I have three screens, one of which is in portrait mode, and the waybar doesn't fit on it and isn't useful on two of the screens. Ideally, it would be good to have different, smaller waybars that only show the name of the monitor and its workspaces, for example.
Do you have any idea how to do this without breaking future updates?
Thank you.

I don't believe that you can b/c of how waybar works.

The trick would be to be able to manage ‘waybar’ and associate them with the monitor defined in ‘monitors.conf’.

monitor = HDMI-A-1, 1920x1080@60, 0x0, 1 
monitor = HDMI-A-2, 1920x1080@60, 0x0, 1, mirror, HDMI-A-1
monitor = DP-1, 1600x1200@60, 0x1080, 1 
monitor = DP-2, 1920x1080@60, -1080x0, 1, transform, 1

It works well, but you need a configuration file for each ‘waybar’ like this:

waybar_DP1.jsonc :

{
  "layer": "top",
  "output": "DP-1",
  "position": "top",
  "height": 30,
  "modules-left": ["hyprland/workspaces", "hyprland/window"],
  
  "hyprland/workspaces": {
    "format": "{name}",
    "on-click": "activate",
    "on-scroll-up": "hyprctl dispatch workspace e+1",
    "on-scroll-down": "hyprctl dispatch workspace e-1"
  },
  "hyprland/window": {
    "format": "{title}",
    "swap-icon-label": false
  }
}

waybar_DP2.jsonc :

{
  "layer": "top",
  "output": "DP-2",
  "position": "top",
  "height": 30,
  "modules-left": ["hyprland/workspaces", "hyprland/window"],
  
  "hyprland/workspaces": {
    "format": "{name}",
    "on-click": "activate",
    "on-scroll-up": "hyprctl dispatch workspace e+1",
    "on-scroll-down": "hyprctl dispatch workspace e-1"
  },
  "hyprland/window": {
    "format": "{title}",
    "swap-icon-label": false
  }
}

waybar_HDMI-A-1.jsonc :

{
  "layer": "top",
  "output": "HDMI-A-1",
  "position": "top",
  "height": 30,
  "modules-left": ["hyprland/workspaces", "hyprland/window"],
  "modules-center": ["clock", "custom/my_module"],
  "modules-right": ["mpris", "pulseaudio", "network", "cpu", "memory", "tray", "custom/power"],
  
  // MODULES
  "hyprland/workspaces": {
    "format": "{name}",
    "on-click": "activate",
    "on-scroll-up": "hyprctl dispatch workspace e+1",
    "on-scroll-down": "hyprctl dispatch workspace e-1"
  },
  "hyprland/window": {
    "format": "{title}",
    "swap-icon-label": false
  },
  [...]
  "cpu": {
    "format": "{usage}% 󰍛",
    "interval": 5,  // Update every 5 seconds instead of 1
    "min-length": 5,
    "format-alt": "{icon0}{icon1}{icon2}{icon3} {usage:>2}% 󰍛",
    "format-icons": ["▁", "▂", "▃", "▄", "▅", "▆", "▇", "█"],
    "on-click-right": "gnome-system-monitor"
  },
  [...]
}

and you have to start each waybar independently, and it works very well...

exec-once = waybar -c ~/.config/waybar/waybar_HDMI-A-1.jsonc
exec-once = waybar -c ~/.config/waybar/waybar_DP1.jsonc
exec-once = waybar -c ~/.config/waybar/waybar_DP2.jsonc

In fact, if you simply add the line "output": "HDMI-A-1" to your ‘/.config/waybar/config’ file,
you can already choose which monitor the Waybar is displayed on ;-)

Glad you found a working solution but that's not something we are going to add to this project

[steveoriol]

In fact, even "output": [ "HDMI-A-1", "DP-1" ], works to display it on only 2 of the 3 monitors...
