hyprctl keyword monitor cannot re-enable a disabled monitor

[slothish]

Description

After disabling a monitor via hyprctl keyword monitor "eDP-1, disable", attempting to re-enable it via hyprctl keyword monitor has no effect. The monitor stays dark. TTYs are also black (output disabled at KMS level). Only a full Hyprland restart restores it.

Steps to reproduce

hyprctl keyword monitor "eDP-1, disable"
sleep 2
hyprctl keyword monitor "eDP-1, preferred, auto, 1"
# or with explicit resolution:
hyprctl keyword monitor "eDP-1, 1920x1080@60, 0x0, 1"

Expected: monitor comes back on.
Actual: monitor stays off. TTYs also black.

Workaround

DPMS works as a substitute for simple blanking:

hyprctl dispatch dpms off eDP-1
hyprctl dispatch dpms on eDP-1

DPMS does not fully disable the output (workspaces remain assigned), so it is not a complete equivalent — but it restores the display reliably.

Context

• Hyprland 0.55.2
• Arch Linux, laptop internal display (eDP-1)
• Use case: lid switch binds — disable internal panel on lid close, re-enable on lid open
• Related: config/lua: allow re-enabling monitors #14447 fixed re-enabling monitors via the Lua config API (hl.monitor.disabled = false). The hyprctl keyword monitor IPC path has the same underlying problem but was not addressed by that PR.
