Is anyone aware of the state of modern standby (S0ix/S2idle) in ubuntu?
From what I can gather, there is support for it in the kernel, but I couldn’t find any specifics regarding ubuntu (there is a post on reddit but the subreddit is set to private…).
I have a device (convertible) that only supports S2idle and it works just fine with Ubuntu 23.04 if I configure properly its webcam, so I’d say it’s more a problem of if all hardware is supported than if the kernel supports it.
You may want to check if your device has any problems going to this website and searching for your actual model:
