Laptop won't suspend

[Kaye]

Hey everyone,

When I close the lid to my laptop, nothing happens! I'm running Mint 6 and everything else seems to work fine after some tweaking except for hibernation/suspend. When I try to hibernate, I get this code:

Code: Select all

LNXPOWER: 00 Error Code: -8

and as I said earlier, closing the lid does nothing. Here's the result of lspci (I assume someone will ask for it):

Code: Select all

For hibernate to work you need a large enough swap. How much RAM does your laptop have and how big is the swap? How many running apps do you have when you hibernate? I also see from your previous posts on the same issue that hibernate used to work sometimes on your laptop, and now it doesn't work at all - what changed?

The hibernate functionality is the same as before - that is, it doesn't work as it should. I get that error code, and it only wakes up successfully about 20% of the time. My swap is 1.5 gigs (I have 3 gigs of RAM), with a 12 gig Ming partition and a 134 gig data partition.. plus, when testing hibernate I only had a simple gedit process running. It might have something to do with the fact that I'm running a dualboot with Vista, but I don't see how that would effect it.

For me what changed was installing Felicia. Now it won't Suspend, Hibernate, or even reliably Shut Down. When doing the latter, I have to wait 45 seconds to see if it worked. 75% of the time, it doesn't.

Kaye - If you have 3 gigabytes of RAM you need a 6GB swap partition. No way it will work with only 1.5. This is because the memory is written to swap when you suspend it (that's how Linux wakes up after that and restores everything to its previous state), and you need place to hold all that memory + everything else that's already in the swap before the suspend.

Locutus - Are you able to properly shut down when running off the Mint 6 Live CD? Perhaps the upgrade didn't go so well... I don't know.

6GB of swap??? woa my god NO! With 3GB of RAM you can use Linux WITHOUT swap. The rule that says you need twice as much swap as RAM is valid with less than 1GB RAM. After, 1GB should be enough, except maybe if you make some "very big works"

I have used Linux (several distros) with 1GB RAM and 1GB swap without problem and I could hibernate... but hibernation is sometimes a problem under Linux, it's not always very stable...

I don't know what laptop you have but perhaps you may read this topic, it can be interesting...

Sorry Udi, but you need to go back to the books on that one! linuxviolin is correct and the thread starter's problem with hibernation/suspend most likely has little if anything to do with swap in this case.

Hibernation/suspend is an ongoing, hit and miss problem in Linux. A real fix seems to be on the horizon, but it isn't here yet.

The best advice I can give is to spend a lot of time Googling and try the various solutions that others have gotten to work. But the fix for every mix of hardware seems to be a bit different.

It wasn't an upgrade. I did at first and had this problem, then for different reasons I bought a new hard drive and did a clean install of both 32-bit and 64-bit versions. I still have this problem.

But I didn't in Mint 5, so there's a regression somewhere. I would go back to M5 but there are features in M6 that I want and are not available in M5.
