However as soon as I toggle that switch to on, it works perfectly, the monitor goes into low power mode exactly as intended. The problem is, it locks my desktop and I keep having to enter a password which is driving me insane
I just want my monitor to turn off WITHOUT screen locking!
I can confirm this symptom too. Because after manually screen locking & shutting monitor down with Super+L it wakes up and stays awake all because of any stupid random notification
