Opensuse 11.3 Hibernation on disk

English Hardware
#1

Hi, I have a problem with Suse and I wonder if anyone can help me:
I’m running a SUSE 11.3 64 bit with the kernel installed friom repo
when I send the hard disk suspension the screen goes black, the SUSE chameleon image appear on the screen for about a second with a progress bar ,then the monitor goes into standby ,the system still running and I have to manually restart.
I also tried to run s2disk-r / dev/sdb6 console or via pm-hibernate with similar results.
I have ever had similar problems with previous openSUSE (swap partition is not defined, problems of user privileges to be assigned for the suspension) but I was always able to solve them, this time I have no idea what it might be.
One thing I noticed is that the swap is not used, even if enabled, but basically I do not even the heavily occupied RAM.
Thanks in advance for any help

I am attaching my configuration files:

Disable the progress bar, get the textual info.

Better.

Disable the splash and retry. Better if you are in text mode already
(ctrl-alt-f1). If that fails, try in runlevel 3. If that succeeds, video is
a problem: change driver (propietary/open).

Or use SUSE Paste

Should I have to reinstall again?
Maybe a package check on repair system would get the system to work…
Now i remember that when I performed the installation I deselect all default package selection and I installed only a very minimal system; after I put Xorg and finally KDE4.
I have doubts about some essential package is missing … Grub also has a text menu not the standard graphical menu.

If you selected the minimal or text pattern, that would be expected.

You can check if there is something missing:

zypper verify

should report if something is missing (except if it doesn’t depend on
anything).

Suspension on RAM works flawlessy; Hibernation on disk succeed if i launch pm-hibernate with the option --quirk-radeon-off ( I have a Sapphire Radeon 9600 XT)

#7

Maybe this helps you, the first time I installe opensuse on my 6gb ram laptop I create a 2.5gb swap partition… and I have the same or similar problem you have. Then I read somewhere (I think in the installation readme) that you need the same amount of swap partition as the ram you have. So, I just resized my swap partition and enable it and now hibernation works fine!

#8

Thanks for the reply; well i don’t think this can be a problem because i’m reusing the same swap partition ( i perform a new installation whenever a new version opensuse come out but the partitions are the same reformatted) and in the previous installations even with problems involving hibernation i always succeed to make hibernation work at last.
Anyway i have 1 GB RAM and about 1 GB swap.

#9

I know that the swap in linux is not used too much like in windows (you told that you noticed its not used, so that is normal) so… the only thing I think is that you have not enable the swap (you may have it created but the system is not using it)

If you su to root, you have some commands like swapon, swapoff… you can enable it if it is in your fstab, hope it helps you :frowning:

That’s too little of both. It is enough on normal use, but the moment you
hibernate, you need more: there must be as much free swap as memory is in
use at that moment. However, the system should abort the hibernation and
tell you why.

Which is why I told you days ago to disable the splash display.

So your problem is video.

After finding this thread I managed to get more robust hibernate and suspend working. To preserve the X Session I use Ctrl-Alt-F1 and login text console. From there I simply call up a very simple bash script which remakes my swap partition (before this thread I had been thinking that virtual paging was corrupting the space but maybe that was a red-herring and I can take those lines out) and then call pm-hibernate with --quirk-radeon-off. I am not 100% convinced the quirk is necessary but I’ve not had any failures yet with it in so it may as well stay.

With the script and a symlink to it moved to my home/bin folder and also a Sudo nopasswd exception created in Yast for pm-hibernate and suspend its very quick and painless. On resume ctrl-altF7 takes me back to my X Session and I have 1-click script top restore internet via ifdown/ifup.

One thing I am am clueless about how to achieve though is the security login prompt that I would get is I successfully hibernated or suspended via the normal UI route e.g. via ctrl-alt-del

pm-hibernate is supposed to be used for debugging only they say although the absence of a login prompt on resume is the only thing that I can tell is missing.

If I could add that then I would feel happier and more secure.

Ideally it would be great to be able to call the same ctrl-alt-del Hibernate or Suspend from the text console. The items are in the Slab Menu so I guess there must be some way of finding out what they call?

Any ideas welcome ;>}

Well, that’s about what I do, except that I call pm-hibernate as root.
There is another command that can be called from the CLI as plain user, but
I don’t remember which one it is… ah, yes, “powersave -U”. It depends on
policy kit.

This one you could automate it, with a script in /etc/pm/sleep.d/

Ah, yes. You have to activate the screensaver. Perhaps calling it manually.

ctrl-alt-supr? Inittab.

On occasion I got the power button to trigger hibernation. Some versions it
worked, some did not.

Thanks Carlos

Using powersave seems to throw in some additional stuff and the console output shows the internet problem. It slows the process down a bit but not too much.

I found this link for anyone else coming to this thread in future Suspend Stress Testing - openSUSE

Using powersave rejects the --quirk-radeon-off parameter but so far there doesn;t seem to be a problem… maybe because I am calling from runlevel 3

On resume it hangs after process at “resuming…” but just hitting return key completes resume in a nanosecond and brings up shellprompt on next line.

I don’t know if the quirk thing will become relevant again but it would be useful to know how to add quirks. I am not totally sure there.

Adding the script for eth0 restarting internet in a user created file 99local which I put in sleep.d (with executable set via gnomesu chmod u+x 99local) did the trick as you suggested. Thanks for that.

In inittab it gives the cli for ctrl-alt-del for when the key combo is used in text mode runlevel 3.
However I am after what ctrl=-alt-del does in GUI mode. In GUI mode that key combo brings up a popup window with options for Suspend Hibernate Restart Shutdown and choosing Suspend or Hibernate from them includes the login prompt.

I don’t know how to activate the screensaver. Surely the login prompt must be a component item of the resume process? There must be a separate call for that?

#18

gnome-session-save --shutdown-dialog

In X Window this opens a dialog which contains Suspend and Hibernate buttons

So what I want to find out are the calls these GUI buttons make so that I can duplicate the functionality in text mode

Another thing Carlos …Why do you use pm-hibernate instead of powersave -U ?

It is not hanging at all, it is the normal behaviour of that program.

It is not a user script, it is a system, root, script. Do not use sudo
there. You have examples in
“/usr/share/doc/packages/pm-utils/examples/hooks/”. The system scripts are
in “/usr/lib/pm-utils/sleep.d”.

Yes, but you can simply switch to text mode and there type ctrl-alt-supr there.

Notice that runlevel 3 is not when you type ctrl-alt-f1 to go to text mode,
the graphical session is still running in VT7. Runlevel 3 means typing
“init 3” as root, which kills the desktop.

No, when the desktop suspends it first calls the screensaver, which in turn
locks the display and asks for the password. This happens before
hibernating, but you see it later. It is a program. The problem is calling
it as the user running the desktop.

It is also possible to adapt the scripts so that when you call hibernation
it goes to text mode before hibernating: I got the trick in a bugzilla,
I’ll look it up later for you.

You could call the screensaver in background, then hibernate, in the same
command line, in the desktop.

Could be. But you have to do the call inside gnome, or the script will not
know about the running desktop.

Try gnome-screensaver, gnome-screensaver-command…

The first one is not the one. AH, you need the second one, look:

cer@Telcontar:~> gnome-screensaver-command --help
Usage:
gnome-screensaver-command [OPTION…]

Help Options:
-h, --help Show help options

Application Options:
–exit Causes the screensaver to exit gracefully
-q, --query Query the state of the screensaver
-t, --time Query the length of time the screensaver has
been active
-l, --lock Tells the running screensaver process to lock
the screen immediately
-c, --cycle If the screensaver is active then switch to
another graphics demo
-a, --activate Turn the screensaver on (blank the screen)
-d, --deactivate If the screensaver is active then deactivate
it (un-blank the screen)
-p, --poke Poke the running screensaver to simulate user
activity
-i, --inhibit Inhibit the screensaver from activating.
Command blocks while inhibit is active.
-n, --application-name The calling application that is inhibiting the
screensaver
-r, --reason The reason for inhibiting the screensaver
-V, --version Version of this application

It gives commands to the running screensaver. You need "
gnome-screensaver-command --activate --lock"

I don’t remember :slight_smile:

Possibly because powersave refused to run. It checks if you have
permissions, or if your machine is listed as being able to hibernate, or
listed as not being able to. Instead of fighting that battle, I simply call
pm-hibernate as root.

Why not as user using sudo? Good question. Supposing I didn’t try and it
failed (I don’t remember), sometimes I’m lazy and continue doing it as root
instead.

O:-)
