For laptop owners: What is the landscape of linux sleeping policy like 2026, i.e. S0ix vs S3? (lemmy.world)

I read how most laptop vendors nowadays force S0ix (Modern Standby). You can no longer pick S3.

On Linux the names for these policies in the kernel are:

  • deep, aka the S3 sleep or suspend to ram

  • s2idle, aka the new Modern Standby or S0ix or suspend to idle.

I am thinking of getting the new Framework laptop, but after talking with their CS, they mention that all Framework will run on S0ix and will not support S3 sleep.

There was a video of LTT bashing S0ix/Modern Standby years ago and he was correct. I had a Thinkpad and it defaulted to S0ix: resume and suspend were very unpredictable. Luckily that laptop also supports S3 so i can just switch to it.

Is resume / suspend getting better on Linux with this forced S0ix? Or i better hold on to an old laptop with S3 lol?

BTW, those with Framework, is resume/suspend reliable? Almost Mac like?

S0ix is fine. LTT doesn't know shit about shit. I use it on first gen Framework. It works way more reliably than S3 since there's little nees for special handling in drivers and firmware. The Framework already consumes 3W when idle. S0ix brings that down to 1-2W. The first gen suppprts S3 and that doesn't consume less power. So either way I need suspend-then-hibernate or suspend-to-both and that's what you want as well. You'd have to forgo Secure Boot to enable hibernate. If root is on Ext4 on encrypted LVM, hibernate works even with a swapfile (default on modern Ubuntu). For fancier setups like root on ZFS you'd need to use encrypred swap partition for it. That's what I currently use. If you want to know more details, have Qs, ask away.
