Don’t know if anyone has tried or if it’s well known, but I did. There was a brief period where I could wake it with my Xbox series controllers but then valve pulled the feature for bugs which I never experienced.
I first tried with the dongle which wakes it as expected on my Linux desktop and my steam deck. Then I paired it with Bluetooth mode and was able to wake it without issue.


My 8bitDo Ultimate 2 wakes my Steam Deck.
Is it the LCD model? Because valve pulled an experimental feature. It momentarily worked on my Xbox series controllers but then it was pulled. I don’t know why, people claim the BT version can’t support wake but that’s obviously false.
Yes, it’s been reintroduced in the latest stable update (3.8)
Weird I still can’t wake with Xbox series controllers.
Yes, Gen1 LCD. Like the other person said has been working for a while but I’m on beta updates.
Ah, I’m on stable. My Xbox controllers still won’t wake it.
