Bug

Description

I have the ThinkPad Basic Dock (40AG0090US) (and a ThinkPad P14s Gen 1) which provides DisplayPort (Passive) over USB-C and/or a proprietary connector.

This does not happen if the laptop is connected to HDMI directly.

When the laptop is asleep, I sometimes connect it to the dock and then wake it up from sleep. Every time I do this, Hyprland crashes.

How to reproduce

1. Run systemctl hibernate.
2. Connect monitor (details above).
3. Wake up laptop.
4. Observe getting kicked to TTY.
