plugins:Description
Got crash during plugging external monitor to laptop, plugged that monitor many times with the same hyprland & hyprlock configs, worked fine. I also have systemd service which runs during monitor plug/unplug to update hyprland monitor config, crash happened during that service execution.
How to reproduce
Create monitor_setup.sh script:
#!/usr/bin/env bash
# Check if HDMI is connected
if ! hyprctl monitors | grep -q "HDMI-A-1"; then
# If HDMI not connected, check if eDP-1 is disabled
if ! hyprctl monitors | grep -q "eDP-1"; then
# Enable built-in display if it's disabled
hyprctl keyword monitor "eDP-1, 1920x1200@60.00, 0x0, 1"
notify-send "Monitor Mode" "Switched to built-in display (HDMI disconnected)"
eww close-all && sleep 1 && eww open bar-win
exit 0
else
notify-send "No external monitor detected"
fi
exit 0
fi
# Check current state (is eDP-1 disabled?)
if hyprctl monitors | grep -q "eDP-1"; then
# Currently in EXTENDED mode → switch to EXTERNAL-ONLY mode
hyprctl keyword monitor "eDP-1, disable"
hyprctl keyword monitor "HDMI-A-1, 1920x1080@100.00, 0x0, 1" # Center external
notify-send "Monitor Mode" "HDMI-A-1 Only (eDP-1 disabled)"
eww close-all && eww open bar-win
else
# Currently in EXTERNAL-ONLY mode → switch to EXTENDED mode
hyprctl keyword monitor "eDP-1, 1920x1200@60.00, 0x0, 1"
hyprctl keyword monitor "HDMI-A-1, 1920x1080@100.00, 1920x0, 1"
notify-send "Monitor Mode" "Extended (eDP-1 + HDMI-A-1)"
eww close-all && eww open-many bar-win bar-win-ext

Try to plug/unplug external monitor
