[gentoo-user] Standby

[gentoo-user] Standby

[Paul Gibbons]

I have failed in the passed to get  standby  working properly. There
are various wiki notes but none seem to work properly. I know this is a
bit vague but maybe I have missed something at the top level. Would
someone mind making a list of pertient things I need to do. I can then
go and read the relevant wiki pages ( and maybe update them with my new
understanding).

I am using 2.6.22-gentoo-r5 86_64 AMD Athlon(tm) 64 X2 Dual Core
Processor 4200+ AuthenticAMD.

I have in the passed got to the point that pressing the power button
shut the system down and added an entry into my grub menu.lst of:

### BEGIN HIBERNATE SENTINEL

title
_____________________________________________________________________
configfile dummy title WARNING: Linux 2.6.22-gentoo-r5 is suspended via
Software Suspend! configfile dummy
### END HIBERNATE SENTINEL


but when I pressed the power button again it performed a full restart.

Thanks for any advice.

Here are some things that I do:

1. My method is to keep grub.conf the same regardless of whether I'm
hibernating or not:

title Gentoo (Linux 2.6.22s2-r1)
   root (hd0,2)
   kernel /vmlinuz-2.6.22-suspend2-r1 root=/dev/hda7 video=vesafb:ywrap,mtrr,1280x1024-32@60 splash=silent,theme:livecd-2007.0  CONSOLE=/dev/tty1
   initrd /fbsplash-livecd-2007.0-1280x1024

When the kernel has loaded, it then looks for a valid suspend image in
swap (or hd).  If it finds one, it uses it, if it doesn't, then it
continues booting as normal.

2. I should mention that I'm using suspend2-sources.

3. the suspend2 users mailing list is an excellent place to find help
with wierd my-system-won't-suspend issues.

4. my /etc/acpi/default.sh has this in it:

case "$ev_type" in
    button)
        case "$event" in
            power)
                logger "acpid: default.sh hibernate"
                /usr/sbin/hibernate
                break
                ;;
...

5. and lastly if, when you boot, you can't "resume", it sounds like you
haven't specified where your suspend image is.  Either in the kernel:
CONFIG_SUSPEND2_DEFAULT_RESUME2="swap:/dev/hda10"
or on the boot line:
resume=swap:/dev/hda10

If that still doesn't help, post back with the output of `dmesg | grep
-i suspend` after you've tried to resume.

Re: [gentoo-user] In-Kernel Standby [Fork of Standby]

This topic has gotten me wondering.  I used to us Suspend2-sources, but
on my current laptop install I'm just flying with gentoo-sources using
the built in suspend.  What are the important differences?

Sometimes upon trying to execute the hibernate script, it will fail with
some kind of "Access denied" or some such, but I've never been able to
determine exactly under what circumstances that happens.  It might be
when I've been using the swap space for actual swapping, but I've not
actually confirmed that.  Anyone knowledgeable care to chime in?

Not so sure about the knowledgeable part, but here it goes:

Some devices are not managed successfully by acpid.  You need to either shut 
them down/bring them up by hand or amend your hibernate scripts to do so, 
prior to hibernation taking place.  Modems and USB devices are the usual 
suspects.

If you run out of space it will tell you so in syslog.

Now someone more knowledgeable could build this up a bit.  ;-)

HTH.

Here is a good list:
http://www.tuxonice.net/features

IMHO the most important advantages of suspend2 are lzo-compression
(providing a good speed up on virtually any machine), encryption (if
you're paranoid or concerned enough to use it) possible usage of swap
files and a higher performance after resume due to the fact that the
whole memory is saved and not only the necessary parts.

I don't know how many changes in the scripting exist, though and I've
never tried suspend1.

Thanks for the advice. Hopefully I can get enough functionality with
swsusp from gentoo-sources and so not need to change to
suspend2-sources - although that may be a very procedure?

Anyway I have created a 32GB SWAP partition (dev/sda5) and gadded
resume=/dev/sda5 to the boot options. And also made the suggested
change to /etc/acpi/default.sh in point (4) above. Now when I press the
soft power button the system suspends ( all processes appear to stop
and the screen goes blank but for a flashing cursor in the top left of
the 2 screens of my dual headed system) but after a few minutes the
system resumes. It seems that either a wakeup message is being received
or the hibernate script cannot actually power off the computer and so
after a timeout period it resumes.

Sounds as if your BIOS is set to wake up on events that get triggered
when in standby. Things to check would be:
- Interrupts in general, there might be some spurious ones,
- Mouse/Keyboard (at least with a sensitive optical mouse...)
- Network
