acpi sleep state S3 (suspend to ram)

Hi everyone,

I just subscribed to the list, and would gladly search
through the 
archives if nobody has a quick reply.

Basically, I would like to get ACPI sleep state (suspend to
ram) S3 
working on my laptop.

I've tried messing with this for quite a long time. I think
I actually 
had it running about a year ago, but then after some
upgrades I 
accidentally overwrote a config file or something.

In spite of reading the howtos on the gentoo wiki and from
gentoo.org, 
even using the default hibernate scripts and acpid, I still
have no 
success.

My goal - to achieve an S3 sleep state when I close the lid
of my laptop 
and to have it wake-up when I open the lid.

In no way am I a newbie to Gentoo and I would love to hear
some of the 
nitty gritty technical details if any of you have them, so
that I can 
keep everything in mind for the future.


My hardware is:

Manufacturer: 'Eurocom'
Model: M560A 'Divine'
CPU: Intel Pentium-M 800 MHz -1.73 GHz

ACPI information:
cat /proc/acpi/processor/CPU0/power
active state:            C2
max_cstate:              C8

Kernel:
2.6.21 (self-rolled)

I've had S3 (suspend-to-ram) and S4 (suspend-to-disk)
working in the 
past. But it seemed to have taken weeks of messing around,
and I can't 
afford that kind of time right now.

I used to get S3 working fine in the past too and I'm
currently
experiencing issues with it (it sometimes hangs when
suspending,
sometimes hangs when resuming, sometimes works...). I didn't
search
yet for a resolution. I'm suspecting an upgrade, when I
switch from
2.6.18-suspend2 to 2.6.20-suspend2.

Is anyone else having such issues?

Hi,
when you manage to get Suspend to Ram (STR) working using
command
line, the rest is usually very easy. I'm using
hibernate-script, so it
is enough to run "hibernate-ram" and edit configs
at /etc. You of
course need a kernel compiled with appropriate options
"on" (I don't
have an access to it right now, but it is pretty obvious if
you look
for it).
For debugging, you may want to start with X server switched
off,
unplugged usb devices and (as much as you can) kernel
modules
unloaded. When you manage to get it working with everything
switched
off, you can than add services, modules etc. and to reveal
what (if
anything) is a problem.
The problem in my case was the ATI drivers, with very
unpredictable
behavior - one release was ok, the next one completely break
it. If
STR fails, it is most likely a driver or something. Using
latest
kernel helped. If you manage to find somebody with similar
hardware,
it also helps a lot - I have Thinkpad R60, so I'm not the
one.
As for the kernel version, I'm using 2.6.22
(suspend2-sources) and I
have seen significant improvement in reliability when
upgrading from
2.6.21 and 2.6.20, so you may also consider it.
Most importantly, give it a try and if it does not work,
report what, when etc.
Best regards and good luck
Jan

I use a Thinkpad T41 and T43. I have been through this for
months and
never got it to work. I have been at it for more than a
year.

My experience is... Forget it, it does not work! I do not
use it at all
and simply shut down when not in use!  Much easier, and less
power
consumption!

I think that's my problem, S3 works when it suspends, but
then when I 
resume all that I get is a blank screen, and I"m also
using 
ati-drivers-8.39.4 and the linux kernel 2.6.21.6.

I remember in the past differing versions of the ATI drivers
would 
completely break the software suspend.

Would you mind posting your /etc/hibernate-ram.conf ? Which
ATI card do 
you have?

Many thanks,

Chris

Take a look at s2ram program. It implements many tricks for
resuming
correctly on different hardware configurations.
Use CVS version as it is more featured.

I had it working for a while, but it is sadly _such_ a pain
to get the 
configuration right, especially for people with drivers that
aren't 
properly implementing power management.

I'm not sure if that's actually true, but I suppose it
depends on the 
length of time the machine is left asleep.

A laptop can use approximately 1 A during boot sequences,
but when in S3 
it only uses about 25 mA, which is 1/40th of the power
consumption.

i1 * t1 == i2 * t2

would sufficiently describe the threshold, when acpi s3
begins to take 
more current than just shutting down, where t1 is the time
required to 
shut down and restart all services, desktop, applications,
etc. until 
you are at the same state when you left off. i1 is 1A, i2 is
~25mA and 
t2 is the amount of time you leave the laptop
suspended-to-ram.

As an example, if your laptop required 5 minutes to
shutdown, restart, 
start your desktop and whatever applications you were
running, then if 
you left your laptop asleep for t2 = 1/0.025 * 300s == 12000
s == 3.3 h 
you would start using more power than shutting it down and
starting it 
up again.

Bottom line is, though, that S3 is just more convenient

True.  In the future, I would REALLY like to get it working!
 I wanted
to roll out a "line" of linux thinkpads with my
custom Gentoo setup on
them.  I have alot of really great stuff that I should be
able to
"ghost" including Blender, Kino, Audacity,
Scribus, Gimp, Kstars, Gnome,
Wifi, IRC, etc... I have a few set up already and it is
fairly easy to
copy onto new laptops.  I would really need ACPI to work
right in order
to market it as a real solution though.

Aside from maybe Ubuntu (not true in a couple of cases), I
have never 
seen a distro that 'just works' out of the box, so if you
could cover 
that market, more power to you 

... sigh, I think I might eventually buy a macbook just for
the battery 
life.
