Based on my research, the steam deck lcd should be able to wake when a controller connects with it. Yet when I paired and enabled wake on Bluetooth for any of my controller it doesn’t work or connect.
Am I doing something wrong?
The controller I’ve tested are
Xbox One
Xbox Series X
PS4
PS4 V2
All controller have been updated by their respective systems.


Oh, the ones who made the last steam machine and controller and supported them for 10 minutes
Valve made no Steam Machine before the upcoming one. Are you confused and meant the 3rd party devices that were branded Steam Machines? Those were not by Valve and not by the Half-Life development team in particular.
Steam Controller 1 is still fully supported and got Bluetooth firmware several years after release: https://store.steampowered.com/news/app/353370/view/3931035846865617357
