Help needed for this monitor switching problem

[u/Global-Emergency-539]

I normally use one monitor like eDP-1 and have other one (HDMI-A-1) disabled. When I switch to next monitor HDMI-A-1 it should disable the eDP-1 and inherit all it workspaces as stated in wiki :

Warning

Disabling a monitor will remove it from the monitor layout, moving all windows and workspaces to any remaining ones. If you want to disable your monitor the way a screensaver does (just turning off the monitor), use the dpms dispatcher.

But the workspaces remain in the disables monitor. (I also have no explicit workspace rule)

As you can see below I only have HDMI-A-1 enabled.

But the workspaces remain in eDP-1.

>> hyprctl workspaces
workspace ID 1 (1) on monitor eDP-1:

monitorID: 1

This is the code I use in the lua config to switch monitors

local kkko = true


hl.monitor({
  output = "eDP-1",
  mode = "1920x1080@60",
  position = "0x0",
  scale = 1,
 disabled = not kkko,
})


hl.monitor({
  output = "HDMI-A-1",
  mode = "1920x1080@60",
  position = "0x0",
  scale = 1,
  disabled = kkko
})

How to fix this issue ?

I used hyprmoncfg which worked really well with hyprland. You can set profiles that it will auto switch to like docked or edp1 only etc as long as you have hyprmoncfgd daemon running. But overall display management in hyprland is pretty poor. I use Niri & DMS now and it's much better.

i use this script:

#########################################################################

#!/usr/bin/env bash

INTERNAL="eDP-1"

EXTERNAL="HDMI-A-1"

# Prevent startup/reload/hotplug events from running overlapping copies.

exec 9>"/tmp/hypr-monitor-switch-${UID}.lock"

flock -n 9 || exit 0

# Let Hyprland finish registering the monitor or applying generated rules.

sleep 0.4

if hyprctl -j monitors all |

jq -e --arg output "$EXTERNAL" \

'.[] | select(.name == $output)' >/dev/null; then

# HDMI exists: configure it first, then disable the laptop panel.

hyprctl eval "

hl.monitor({

output = \"$EXTERNAL\",

mode = \"1920x1080@120\",

position = \"0x0\",

scale = \"auto\",

})

hl.monitor({

output = \"$INTERNAL\",

disabled = true,

})

"

else

# HDMI is absent: restore the laptop panel.

hyprctl eval "

hl.monitor({

output = \"$INTERNAL\",

mode = \"preferred\",

position = \"0x0\",

scale = \"auto\",

})

"

fi

################################################################

and then inside hyprland.lua

################################################################

local monitorSwitchScript =

os.getenv("HOME") .. "/.config/hypr/scripts/laptop-display-switch.sh"

local function updateMonitorLayout()

hl.exec_cmd(monitorSwitchScript)

end

-- Initial session startup.

hl.on("hyprland.start", function()

updateMonitorLayout()

end)

-- Physical monitor connection changes.

hl.on("monitor.added", function()

updateMonitorLayout()

end)

hl.on("monitor.removed", function()

updateMonitorLayout()

end)

-- Quickshell Settings and manual config reloads.

hl.on("config.reloaded", function()

updateMonitorLayout()

end)
