I hope they implement it better than MS did for Windows 10/11. I recently setup a Windows 11 machine for work and had to enable hibernate specifically because S0 sleep is incapable of staying asleep for more than 30 seconds despite me disabling literally every device from being able to wake it up.

New Runtime Standby ABI Proposed For Linux Akin To Microsoft Windows' "Modern Standby"
(www.phoronix.com)
I feel this. Initially I just closed the lid on my work laptop, but I kept waking up to my work monitor just sitting there shining in the middle of the night, because despite having put it in hibernate, it decides to spontaneously wake up and sit at the login screen. Couldn't ever fix that, so now I unplug it when I quit my workday.
Modern Standby is a low-power mode on Windows 11 for letting systems remain connected to the network and appear "sleeping" but will allow for instant wake-up for notifications, music playback, and other functionality. The display is off, the network remains online, and background tasks can wake-up the ystem if needed with Microsoft Modern Standby.
So we can add napping to sleep and hibernate
I was forced to use a mac recently. I believe this may be what it also does. It's absolute insanity and I hate the behavior with passion. If I put it to sleep I want it to stay sleeping, dead, not running, not using the network, not draining my Bluetooth headphones that were connected and I expected for them to turn off.. or to keep receiving slack notifications on it instead of them routing properly to the other really connected device....
I hate this timeline.
Well the good thing is that we usually have a choice on Linux. I really hope the term napping for this catches on.
Modern Standby is the thing that causes your notebook to heat up when closing the lid and putting it into your backpack.
It only really works on my Surface, on my work's ThinkPad it merely mostly works, on my private Asus gaming notebook it's entirely broken.
Old standby on my Steam Deck is what works most reliable in my household.
We don't need this crap on Linux. Sleep is meant to be a low power mode where everything except ram is powered down, and you can pick up near instant where you left off. Not this kind of "sleep" where about everything is running like before. A desktop/laptop isn't a mobile phone where this behavior is the standard.
- Not every Linux device is a desktop or laptop.
- Something similar was recently added to the Steam Deck to download updates before going properly to sleep.
Adding this doesnt mean removing sleep. Linux isnt only used for laptops and desktops.
On a semi-related note, does anyone know if there's any modern laptops that still support regular S3 Sleep? Or did they all switch to S0ix?
