Can confirm. I have similar problems with very long uptimes on my MBA M1. By long, I mean two months or more. The most common recurring problem is the Mac forgetting it's connected to a monitor. But the problems are often very random. I've had most of the ones you described.

Though I shouldn't use the word "common" as the occurrences are rare. My guess is 4-6 times a year over the past five years. Would love to know what causes it but the randomness of the symptoms would make investigating a bit difficult.
