Suspend to RAM doesn't recover

English Hardware
#1

Hi,

I was tweaking my system and I discovered that the suspend to RAM recover partially.

First thing : laptop Acer Aspire nvidia GEForce 9600,4Gb RAM, openSUSE 11.3 KDE 4.5.4.

uname -r
2.6.34.7-0.5-desktop

Let me explain what happens. The suspend to RAM work, the laptop does suspend. Here’s the log :

cat /var/log/pm-suspend.log 
Initial commandline parameters:

I recover partially though. That is, the desktop displays almost perfectly with some glitches here and there. The kmenu is accessible, but all the launchers in the panel don’t work. KDE throws a message stating : blablabla.desktop is nowhere to be found.

Tne networkmanager doesn’t respond and network doesn’t recover (it does recover when I hibernate).

When I logged out or reboot, a long list of messages displays and the session never shut down and the PC never reboot. Those messages are related to SATA somethning… Is there a log for that?

So, what’s up doc? :\ What should I do to make it work?

Have a read here
SDB:Pm-utils - openSUSE

SDB:Suspend to RAM - openSUSE

Hi caf4926,

Thanks for the readings. The problem is not that I cannot suspend to RAM. My system does it very well. The problem is getting out of this suspend. It resumes, I have no problem with video, no problem with backlight. I simply cannot get a network connection again and KDE is partially responsive.

As for PM-utils, do I have to create such a hook? I don’t know how and what to put in it?

Disable splash screen (explained recently on another thread).

Try hibernate (to disk).

Try another user (new).

Try another desktop.

Try text mode.

Hi carlos,

I already disabled the splash screen as you suggested on other threads. :wink:

The hibernation goes without an itch. It hibernates and recover perfectly.

The problem is the sleep. It does go into sleep very well, but the desktop recovers perfectly, but is not responsive. The network too.

I will try another user and another DE.

In text mode, the command to sleep is what?

That’s typical. I don’t know why, but full suspend often works better than
suspend to ram. My laptop, for instance, gets a dead mouse in 11.2 (needs
reboot to recover), and an alive one in 11.3, but with other issues.

You could perhaps disable the network manually, via a script. For the
network, I mean. Dunno, perhaps unload/reload the driver. Via hooks.

That will be pm-something. Let me see… here:

Telcontar:~ # pm-[TAB][TAB]
pm-hibernate pm-is-supported pm-powersave pm-profiler
pm-suspend pm-suspend-hybrid

So, pm-suspend. There is another command that also works as user, what was
it…? Ah, “powersave -U” is hibernate, suspend must be another option. Ah,
lowercase -u.

And there is another pair of commands, s2ram, s2disk. As root. But if I
recall correctly, those two do not run any preparation scripts, they do the
final call. Again, IIRC :slight_smile:

I read this document, but I am not sure what to do with it. They’re talking about hooks.

The concept is quite easy:

* The main script pm-action (called via symlinks as either pm-suspend, pm-hibernate or pm-suspend-hybrid) executes so-called "hooks", executable scripts, in the alphabetical sorted order with the parameter suspend (suspend to RAM) or hibernate (suspend to disk).
* Once all hooks are done, it puts the machine to sleep. After the machine has woken up again, all those hooks are executed in reverse order with the parameter resume (resume from RAM) or thaw (resume from disk).
* The hooks do various stuff, for example preparing the bootloader, stopping the bluetooth subsystem or unloading of critical modules.

How do I prgram such hooks?

Ill post an example of mine, it is not that difficult. I’m not sure if we
are talking of the same (haven’t read that document recently), so… But i
know what you need to know :slight_smile:

In /etc/pm there are three directories, one for scripts. That’s the place.
The system scripts are in /usr/lib/pm-utils, and in
/usr/share/doc/packages/pm-utils/examples/hooks/ you have examples.

In /etc/pm/sleep.d/ -> I have 0cosas - that’s 0things. The “0” means that
it is the first one run. It is not a symlink, but a real file.

You see it is a simple case with four entries: hibernate, suspend, thaw,
resume. Ie, ram or disk, sleeping or awakening. The logger entry is a call
to syslog to note the moment where hibernation starts and finishes -
although it might actually be written after the system returns. I’m not
sure. The router call on restoring is a script that logs the current IP I
get from my ISP. It is not currently working, but I leave it as an example.
The /usr/lib/pm-utils/functions line is necesary, I understand.

I have a “hook” that aborts hibernation if an external nfs mount is active:
it will crash the kernel. Wrote a bugzilla about this. I have another,
90clock, copied from the examples, that restores the clock from the cmos
clock and restart ntpd.

What are you doing here? You dump something in this directory?

Ok, can I try this script on my system as it is (except for the line where you state your directory of course)?

No, that’s a function where, after a wait of 20 seconds, I call a local
script that logs my IP. You don’t need that all, it was left as an example.

You see that the call to it has an “&” at the end. This way, when the
computer resumes, the call is made and the hook exits, but the call to the
external script actually runs 20 seconds later, giving time for the
computer to really resume and for the router to boot.

Yes, of course. Just remove the function “Router” and the call to it in the
resume section.
