Sleep/hibernate works fine in linux as long as you use fully FOSS components like a thinkpad x200. Stop being such a nigger OP.

Do more research.

>>822762

The info on this topic is very sparse. Most people who run Linux are just happy that the shit boots up and runs (pretty much a given these days), and never even think of reporting whether suspend mode works.

>>822743

>fully FOSS components

>thinkpad x200

You're a delusional cuck if you think any commercially-available hardware is "fully FOSS"

>>822767

Libreboot, and even a Russian re-implementation of the EC is available. Fuck off officer FUD

>using Linux

just install Microsoft Windows if you want hibernation to work

>>822740 (OP)

They can't even get hibernate working on popular i3/i5 chips, you think Ryzen stands any chance?

>>822740 (OP)

use systemd wew

>systemd was planned by microsoft to implement features on windows that should werk

>task scheduler, services, hibernate, encrption, stuff made simple

Problem is youll likely end up in data corruption with linux file systems so you have to shutdown every once in a while

My x220 works with both, and my desktop works for sleep and maybe hibernation (I never use it on either).

I did see a PC that crashed when you tried to hibernate and wouldn't wake up from sleep, don't know what that was about.

>>822740 (OP)

One of the reasons I'm so happy with the Void is the hibernation.

It's just a small script:

#!/bin/sh
# zzz - really simple suspend script

USAGE="Usage: ${0##*/} [-nSzZR]
   -n   dry run (sleep for 5s instead of suspend/hibernate)
   -S   Low-power idle (ACPI S0)
   -z   suspend to RAM (ACPI S3) [DEFAULT for zzz(8)]
   -Z   hibernate to disk & power off (ACPI S4) [DEFAULT for ZZZ(8)]
   -R   hibernate to disk & reboot
   -H   hibernate to disk & suspend (aka suspend-hybrid)"

fail() { echo ${0##*/}: 1>&2 "$*"; exit 1; }

export ZZZ_MODE=suspend
export ZZZ_HIBERNATE_MODE=platform

case "$0" in
  *ZZZ) ZZZ_MODE=hibernate;;
esac

while getopts hnSzHRZ opt; do
  case "$opt" in
    n) ZZZ_MODE=noop;;
    S) ZZZ_MODE=standby;;
    z) ZZZ_MODE=suspend;;
    Z) ZZZ_MODE=hibernate;;
    R) ZZZ_MODE=hibernate; ZZZ_HIBERNATE_MODE=reboot;;
    H) ZZZ_MODE=hibernate; ZZZ_HIBERNATE_MODE=suspend;;
    [h?]) fail "$USAGE";;
  esac
done
shift $((OPTIND-1))

case "$ZZZ_MODE" in
  suspend) grep -q mem /sys/power/state || fail "suspend not supported";;
  hibernate) grep -q disk /sys/power/state || fail "hibernate not supported";;
esac

test -w /sys/power/state || fail "sleep permission denied"

(
flock -n 9 || fail "another instance of zzz is running"

printf "Zzzz... "

for hook in /etc/zzz.d/suspend/*; do
  [ -x "$hook" ] && "$hook"
done

case "$ZZZ_MODE" in
  standby) printf freeze >/sys/power/state || fail "standby failed";;
  suspend) printf mem >/sys/power/state || fail "suspend failed";;
  hibernate)
	echo $ZZZ_HIBERNATE_MODE >/sys/power/disk
	printf disk >/sys/power/state || fail "hibernate failed";;
  noop) sleep 5;;
esac

for hook in /etc/zzz.d/resume/*; do
  [ -x "$hook" ] && "$hook"
done

echo "yawn."
) 9</sys/power

Buy known-good stuff online, or go to a store and make sure there's not a single Broadcom chip in anything bought new. Broadcom is what Theo de Raadt warned us of: an OEM-friendly early-to-market company that does it at the cost of doing it in badly, in software that then needs firmware updates to actually work properly.

You're fucked with x86, it's inherently backdoored.

On topic: gonna try Debian on my ThinkPad X31 soon-ish, making a USB stick for it atm.

>>822740 (OP)

Has worked fine on 2 Dell Inspirons for me, with both i5 and i7.

I've never had any issues with sleep on my systems, most OSes got that together awhile ago

>>822997

>what is management engine

Intel ME is wiped completely off with libreboot being flashed externally. What are you on about.

>>822811

That's nice and all, and it IS an improvement, but it's not "Fully FOSS components."

>>822997

>inherently backdoored

>inherently

I don't think you know the definition of the word "inherent".

>>823043

Libreboot doesn't support any systems with ME. It's one of the main reasons it's stuck on ancient hardware.

Maybe this will change soon, people have supposedly found a vuln to run user code on ME.

Seems like HP and Dell are more reliable than modern Thinkpads, at least from my experience. I have a Thinkpad with a 4th gen i5, and suspend is fucked. However, apparently Haswell specifically had a suspend bug.

https://wiki.archlinux.org/index.php/Power_management/Suspend_and_hibernate#Instantaneous_wakeups_from_suspend

I have a Haswell / GTX750ti with proprietary drivers installed. I've never had issues with the Nvidia hardware, but a couple of times when using Haswell GPU I've had to Ctrl+Alt+F3 and kill lightdm to get control back. If you're on a desktop machine, you can just disable sleep suspend and hibernate.

systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target

I second this. I want to hibernate and reboot into win10 for vidyagames. Then come back to where I left off.

I just wonder if having FDE encryption will throw a monkey wrench into these plans.

>>823095

> I want to hibernate and reboot into win10 for vidyagames. Then come back to where I left off.

What the fuck?

>>823100

Hibernate Loonix, restart into Win10 for gamezz, done with games? shutdown Win10, resume Loonix.

>>823060

Blame (((them))) for inherently backdooring x86.

>>823126

Do you change boot sequence in between or can you set the some BIOS to always ask what to boot from?

>>822740 (OP)

try in terminal:

pm-suspend

sometimes with gnome the ui breaks and suspend, shutdown, restart don't work.

Hibernating is for faggots tbqh

KVM, run Windows with the beefy GPU, use Linux simultaneously.

>>823126

that's never how hibernate works dumbass

My X230 worked with everything out of the box, from the suspend to the fingerprint reader.

systemctl suspend

>hibernating a FDE sytem

Enjoy your exposed swap partition with all keys, cucks.

>>823166

There are many driver writers for Linux that are also fans of the Thinkpad. This is the reason why Thinkpads are well supported in Linux.

>>822740 (OP)

Yes. I haven't encountered an issue in a decade.

Well I did have a winxp BSOD on hibernate if that counts?

>>822740 (OP)

Yes, on Lenovo Yoga 300. It's some Bay Trail, I can dump lspci if you care.

Actually, for a while I haven't used a laptop where suspend/resume failed.

I am afraid that won't be possible. When I hibernate my Microsoft Windows, then start PC, it unhibernates Microsoft Windows, I don't have OS choice. I would need to shutdown and boot to see OS choice.

>>823152

>Hibernating is for faggots tbqh

hibernating is for superior people that care about productivity. you are not one of them.

>>823379

>hibernating a FDE sytem

>Enjoy your exposed swap partition with all keys, cucks.

that's bullshit

FDE = Full Disk Encryption. that includes swap.

Especially on Microsoft Windows, as it keeps swap on system partition. Stupid Linux has separate swap partition, but that's because it's inferior to Microsoft's product.

Laptop, Dell Vostro 1520: suspend just werks; both under Windows XP and 7 as well as Linux (any kernel >=3)

Hibernation "works" as well, but takes forever to restore from on both OSs.

Self build desktop with Phenom II X6 CPU : suspend just werks, though Windows sometimes decides to wake up in the middle of the night. Hibernate on Linux doesn't work, the monitor gets turned off, then immediately back on, and I'm back at the login screen.

On Windows, Hibernate just crashes the system (monitor off, computer still running, doesn't accept ANY input whatsoever, have to hard reset)

So, suspend good, hibernate crap, regardless of the OS.

>>823714

Linux allows you to keep swap in file.

With basic secure FDE your swap is encrypted with random key on every boot and key is erased on power off, with hibernate you choose to keep this key persistent. It's not secure though since if attacker accidentally decrypts your file system, xe will also get access to random struff in your ram moments before suspend. However, I suppose, you can save random swap key on an external drive alongside with general encrypted partition key and have more security overall.

>>822740 (OP)

I never had problems with sleep or hibernation under Linux until Debian switched to systemd, then hibernation stopped working.

I said 'fuck this' and moved to Devuan and now it works again.

>>822766

>The info on this topic is very sparse

If you're using systemd, check this out:

https://wiki.archlinux.org/index.php/Power_management#Power_management_with_systemd

I set up my hibernation flawlessly with info from here. And this is on a shitty HP not-free-software-friendly laptop

>>823063

Don't ever touch HP hardware, be it a prebuilt or a printer.

Out of the big names there's not a single worse manufacturer than them.

>>822740 (OP)

Mobo: ASUS M5A99FX PRO R2.0

CPU: FX-8320

GPU: GTX 970

Sound card: Asus Xonar DSX

It all works after suspend: Video, audio, everything. Audio functionality also restored just fine with the onboard.

As for laptops:

Lenovo Y50 4k (last model with 860M).

It jest werks.
