System Freeze on External Monitor
When the lid is closed, an external monitor is connected and the lid is opened with the monitor in, the screen starts going on/off and the system freezes. If I disconnect the screen, it does not change back to the laptop view - system is frozen and needs a hard reset.
- If the lid is opened first, and a screen is connected afterwards, everyting works.
- If the computer went into sleep mode without closing the lid, everyting works.
- Disconnecting and connecting a display when the computer is running works fine too.
My laptop: Lenovo IdeaPad 1 14ALC7 (haven't tested on other systems)
Distro: Kubuntu 23.04, DE: Plasma 5.27.4(Wayland)
