Wake up from suspend to ram *twice*

phoenixRO · 2012-05-10 10:12:31

Hello!

I am running arch on my Asus M51Vr laptop. Whenever I suspend to RAM and try to resume (i.e. hit a key), the laptop wakes up (sometimes without even locking the screen), and after 3-5 seconds it goes back to sleep; if I hit a key again, it will wake up with the screen locked (as configured) and then proceed normally.

This issue appeared some time ago after an update (was not there after installing arch). I am not sure where to start with the search for a fix, could you please help me?

Thank you!

Can you link here your /var/log/pm-suspend.log?

Hey! Sorry for the delay. Here it is:

[root@phoenix results]# cat /var/log/pm-suspend.log

You have very little number of script executed during pm-suspend!
And you have no /usr/lib/pm-utils/sleep.d/99video? How is it possible?
Did you remove some of those scripts?

phoenixRO · 2012-05-13 18:33:02

I actually do have that script:

I did not touch the configuration files (I am not responsible for what pacman might have done).

This apparently overwrites KDE's setting not to stand by when I have the laptop plugged in and I close the lid. The original setting worked like a charm (not plugged in? stand by only once).

Reading through that post, I came across:

the use of acpid always brings up this issue.
It duplicates the desktop manager's call for pm-suspend, one arrives first, the other arrives after resuming the system.
The cure: remove one of the methods to call pm-suspend.
I rather not to use acpid, I don't need it anyway.

I am quite sure that this is also my case, but I am not sure where to remove the pm-suspend entry from (note: there was no call to pm-suspend in that handler.sh file).

Furthermore:

[root@phoenix etc]# grep pm-suspend */* -R
acpi/handler.sh:#                       /usr/sbin/pm-suspend

which is the call I wrote as instructed by the post you linked to.

I had the same problem and I can confirm that removing acpid solved it.
I realized that I didn't need it (I'm using Gnome, in fallback mode). I'm fine without acpid, didn't see a single difference.

patrickthebold · 2012-06-18 23:55:12

Just going to share my own experiences: Before a recent update I manually bound the suspend key to call pm-suspend. There was a recent update that makes this unnecessary which is why it got called twice for me.
