Screen wont turn on resume from pm-suspend

I just recently installed arch after being a long time ubuntu/linuxmint user.  Suspend to ram has always worked fine with the other distros.  However, after installing arch, the laptop will suspend, but when I try to resume, the screen will not come on and I have manually kill the power to the laptop.  I am assuming because of the modular state of arch, I am just missing something I need to configure or install.

I have a radeon graphics card, but I am using the open source driver.
The laptop is running on a dual core amd64 architecture.

Anyone have some time to help me get resume working?

P.S.  pm-suspend.log indicates the suspend was successful, and no errors were logged.

Re: Screen wont turn on resume from pm-suspend

Try using systemd suspend instead of pm-utils.

Re: Screen wont turn on resume from pm-suspend

I am not sure how to do that, but I can try to find some information.  Will systemd suspend be supported by KDE?

Re: Screen wont turn on resume from pm-suspend

Okay, I tried   'systemctl suspend'.  I get the identical behavior.  Could it be something wrong with the newest kernel in arch?  Anyone have a similar experience, or a suggestion?  I would like to remove my ubuntu partition, but I would like to get suspend and hibernate working before doing so.

Re: Screen wont turn on resume from pm-suspend

This one would be my shot. That is what fixed it in my case.

Remember to rebuild your kernel image after the change in mkinitcpio.conf .

Re: Screen wont turn on resume from pm-suspend

Thank you for the help.  Unfortunately, this doesn't fix the problem for me.   I followed the instructions on editing the config file and rebuilding the initrd.  Then, rebooted.  After my system was fully booted up, I attempted the suspend again.  Still the same symtoms.  (Fans come on, screen doesn't.  Then the fans turn off, but the power light stays on.  I have to hold the power button to turn off the machine.)

Re: Screen wont turn on resume from pm-suspend

A pity it did not help.

I remember though having seen similar discussions (not sure though if in the 'Newbie Corner' or the 'Laptop issues' subforum) that you might want to check out in case these can offer a fix for your situation. I hope the forum 'Search' feature will assist you in finding them.

Re: Screen wont turn on resume from pm-suspend

Just an idea.  Have you installed pm-quirks?

Also, are you using a 'resume hook'?

Re: Screen wont turn on resume from pm-suspend

Root:  Yes,  I am aware of the search function.  I have been reading some of the other forum posts.  Still no luck.  Thank you for your help so far. 

David:  I did install pm-quirks.  Also, added the resume hook.  I am starting to think that this kernel doesn't like my laptop.  Or the other way around?  Today I am running a full update/upgrade.  Hopefully whatever package that is malfunctioning will be updated, and the problem will be magically fixed.  If not, I will just have to wait a while to use Arch.  Mint is running fine.  It just doesn't feel as clean as Arch.

Re: Screen wont turn on resume from pm-suspend

You might try adding acpi_backlight=vendor to to kernel boot line.

EDIT:  On second thought, I doubt that will make a difference.

Thanks, but that didn't make a difference either.  This is frustrating!

Re: Screen wont turn on resume from pm-suspend

Okay, interesting discovery:

I installed openSUSE 12.2 over the arch partition on my laptop.  It had the same exact suspend & blank-resume symtoms.

My main linux install is Mint 13 KDE edition. It's current kernel is: 3.2.0-12; Suse was using: 3.4.11-2.16;  and it appears after doing a quick package search on Arch's website, they are using 3.6 something. 

Is it possible that something broke suspend functionality in 3.4 or above?  Or maybe systemd has something to do with it?  Suse and Arch are both on Systemd now.  I doubt it would have anything to do with my hard disk partitioning.

Anyone have some thoughts?

Re: Screen wont turn on resume from pm-suspend

You could try checking out the LTS kernel and see if it makes any difference.

Now that I notice, you do not mention that you had checked any logs regarding this issue. Maybe the clue is in those logs/journal and the error message may offer a hint for a fix of the problem.

Re: Screen wont turn on resume from pm-suspend

You could try downgrading the kernel to a version you know that works.  This should deteremine if the kernel is at fault.

Re: Screen wont turn on resume from pm-suspend

Make sure that you do not have competing programmes all trying to control this kind of functionality. On your system you have at least the following: systemd; pm-utils; KDE. You may also have acpid.

I'm not saying this will solve the problem but it might enable you to diagnose it at least.

Apart from the logs/journal, you might also try booting to the CLI and seeing what happens if you suspend without KDE in the picture. (You should still make sure just one of the remaining methods is operative, of course.)

Is the screen completely blank or does it look as if the backlight is not on but there is output?

You can also try increasing the log level if you don't get enough info otherwise.
