Description Marc Krämer 2018-08-11 13:32:57 CEST
If you do a suspend/hibernate, all powerparameters are reset to default.
powertop --auto-tune should be rerun after resume operation.

Thanks for reporting, but I think you are wrong : this tunes only kernel-parameters that are kept after both suspend and hibernate. I have just ensured in my system :

- display TUNABLES in powertop : all are GOOD
- suspend / awake
- display TUNABLES in powertop : all are GOOD
- hibernate / poweron
- display TUNABLES in powertop : all are GOOD

Feel free to reopen if you have further information.

Resolution: (none) => INVALID

Hi José,
here on my thinkpad many tunables are in bad shape after resume.
Before suspend I checked all values and tuneables are all good.
The using suspend (via lxde) and resuming via powerkey tuneables for ~20 devices are bad.

Did you check your values are in bad shape before using powertop?

I think this can be done via systemd-sleep target.

Yes. Maybe you have something interesting in your hardware. Feel free to contribute a trigger for systemd-sleep, but it should be ignored by default as most hardware does not have this problem and powertop is huge in RAM.
