After last monitor gets unplugged from the system, hotplug detection may no longer work on Intel GFX. This is because we didn't trigger a modeset to disable CRTCs, and i915 requires it to make hotplug detection continue to work [1]. Ensure disabled CRTCs are unset and post a modeset to disable them.
