Talk:Power management/Suspend and hibernate
Modifying the hibernation mode
Hi, I've experienced a couple of problems with the default "platform" kernel hibernation mode on my laptop (basically, sometimes the hibernation image fails to resume, leading to a reboot), so I've been testing the steps shown here . In fact, changing to "shutdown" mode does work. There is a way to force systemd to use a specific mode/state configuration by means of creating
/etc/systemd/sleep.conf according to
man systemd-sleep.conf. I'd add this to the wiki, but I'm not sure which is the most appropriate section to add this information, whether Power management#systemd or Power management#Troubleshooting. --Eugenio M. Vigo (talk) 16:41, 28 March 2016 (UTC)
- I think you can put it under Power_management#Power_management_with_systemd, since sleep.conf isn't mentioned at all in the article yet, and the new section could be expanded and generalized. In any case we're always in time to move it somewhere else if needed. — Kynikos (talk) 07:07, 30 March 2016 (UTC)
Suspend on LynxPoint
I had to disable SLPB and JMC2 too, to avoid instantaneous wakeups from suspend. Should we add this to the list of acpi devices in the "Suspend on LynxPoint" section? Dervomsee (talk) 11:54, 5 March 2017 (UTC)
Is the introduction too long?
- Admittedly the introduction is quite lengthy but nevertheless descriptive and it provides the necessary information to understand the following chapters. IMHO I would keep it as it is. -- Edh (talk) 19:13, 15 November 2017 (UTC)
- Right, I already assumed, that you were just intending to move stuff around without changing the content. Nevertheless I still think that the current introduction is the way to go since it is essential for understanding the following content. However feel free to disregard my opinion. I do not feel to strongly about it. -- Edh (talk) 20:59, 16 November 2017 (UTC)
Suspend then hibernate
To be honest, I find this article somewhat underwhelming when it comes to dealing with modern suspend/hibernation methods.
1. I have personally set up my system to use Intel Rapid Start Technology (IRST), which works great for my purposes, on my machine. Unfortunately it seems that there is virtually no information on IRST on the Arch Wiki.
2. Other than IRST, this page does not make any mention of configuring suspend-then-hibernate (briefly mentioned here).
Both suspend-then-hibernate methods are better than "suspend to both", IMO, since there will be a much shorter delay before going to sleep, and the system will always hibernate after the timeout is reached, rather than when the battery is nearly depleted. This means that you can close your laptop lid, and leave it for a few days yet always be certain that you have a fairly decent amount of battery power left once you resume your system.
Is there a reason this wiki article does not include information on either method, or would it be appreciated if I put time into adding instructions on how to enable them?
Or, in the case of IRST, we should perhaps create a separate page for it? It can then include a list of laptops verified to work with it, since it seems to depend on firmware/BIOS support.
- Just because some information is not there does not mean that it is missing.
systemctl suspend-then-hibernateshould work out of the box assuming that suspend as well as hibernate, both of which are fairly well documented, actually work. The action that should happen when you close the lid can be configured as described in Power management#ACPI events which also includes
suspend-then-hibernate. -- Lahwaacz (talk) 09:39, 17 February 2019 (UTC)
