Prevent PCMCIA power-off

Rheinländer — 2012-11-27T03:34:53

Hi,

how would I prevent pm-suspend from powering off my PCMCIA/cardbus 
cards? I have a network card in there and powering it off prevents 
Wake-on-lan.

Thanks!

fixing (an almost fixed) suspend of the asus 1025c

CG — 2012-11-20T21:38:29

Hardware/software context
=========================
Machine: ASUS eee pc 1025C
CPU: N2800
Integrated graphics processor: Intel GMA3650
OS: Ubuntu 12.04 LTS
kernel: 3.4.0-0304000-generic (note: I upgraded to a newer kernel than
the standard kernel packaged with Ubuntu 12.04. This was required to
exploit several features of the GMA3650.)


Problem
=======
suspend is broken (but almost fixed).


Observations
============
pm-suspend => garbled screen after wake up

pm-suspend --quirk-vbemode-restore => after wake up, screen is black
(that is, the active-type-of-black: the backlight is on). Moving mouse
or keyboard doesn't change anything. This is the case until the default
screen saver becomes active. Then the screen goes completely dark
(backlight off) and after that, moving mouse or keyboard brings back a
visible, and completely correct screen.

I also tried other combinations of quirks, but the results were in each
case one of the above.


Question
========
How can suspend be fixed? The screensaver apparently

Lenovo T420 issues

Athlion — 2012-07-22T15:59:25

Hello all. I have a Lenovo T420 with the integrated intel HD3000 card
(no optimus) and have issues suspending the laptop. What happens is,
briefly, that after I've been using the laptop for about a day or two
(suspending/resuming with no problems) the suspend fails and the sleep
led will start flashing constantly. If I open the lid, I see that X
has dropped back to the display manager and no suspension has taken
place. You can see the thread I have opened in arch linux forums here:
https://bbs.archlinux.org/viewtopic.php?pid=1134478

What's more interesting is that if I try to reboot after the failed
suspend, the system starts rebooting, suspends correctly midway and
finishes the reboot upon resuming.

I am trying to figure the source of this problem as this affects other
laptops as well and in the process I have enabled PM_DEBUG and
collected the /var/log/pm-suspend.log from an OK and from a failed
one. You can find them here:
OK: https://dl.dropbox.com/u/63420/suspend.log.ok
Not OK: https://dl.dropbox.com/

Can't suspend on a Nvidia quadro 3600m

Weedy — 2012-07-17T07:08:05

I used to have a m90 with a 1500m, for the most part it worked if you
exclude nvidia breaking shit every other release.

Now I got a m6300 and along with all the other upgrades compared to
the m90 I got a 3600m. This should actually be a chip with BETTER
support from nvidia but I haven't been able to get consistency out of
it since I swapped hard drives over.

Anyway kernel 3.3.7; x11-drivers/nvidia-drivers 173.14.34, 173.14.35,
295.59 (and a lot more 2xx), 302.17; and pm-utils-1.4.1-r2.
It seems to get stuck going into sleep but for all I know it could be
instantly coming out of sleep and sticking there.

Thanks for your time/ideas.

[PATCH]: Support in-kernel suspend to both (i.e. hybridsuspend)

Bojan Smojver — 2012-06-28T09:21:27

The in-kernel suspend to both should surface soon (hopefully in 3.6), so
here is a patch (untested) for pm-utils.

Re: GIT: [PATCH] Move function log to pm/functions.in

Leonid Isaev — 2012-05-23T16:34:17

Hi,

There is a simple bug in pm-utils' logging logic: some hooks (like
75modules) try to call log() and fail because the hook
sources /usr/lib/pm-utils/functions, while log() is defined
in /usr/lib/pm-utils/pm-functions. This was discovered and fixed by openSUSE
folks back in 2010 for pm-utils 1.3.0, and posted on this list:
http://lists.freedesktop.org/archives/pm-utils/2010-September/002219.html.
However, pm-utils 1.4.1 is still broken. Is there a reason why the
above patch has never been merged?

Thank you,

removing modules in use before suspend

Brian J. Murrell — 2012-04-19T11:38:47

I'm assuming that if as root I cannot remove modules with "rmmod" due to
them being "in use" then pm-suspend won't be able to remove them either,
yes?

How does one resolve the issue of needing to remove modules so that a
suspend doesn't hang but those modules cannot be removed due to them
being "in use" by an application?

Also, as a slightly related question, is pm-utils smart enough to follow
a dependency chain and remove any modules that might be keeping a module
we actually want removed?  So for example if to remove module A I need
to first remove module B, can I just tell pm-utils that I want module A
removed and it will figure out that module B needs removing or do I need
to tell pm-utils to remove "B A"?

Cheers,
b.

Yes, they are.  You can contribute in any area you like -- the easiest
way for me to manage right now is to:

1: Get a Github account, if you don't already have one.
2: Fork https://github.com/pm-utils-hackers/pm-utils.git

forcing chvt with kms (nouveau) driver

Brian J. Murrell — 2012-03-03T22:16:27

I have a Unbuntu laptop with kernel 3.0.0-16-generic which I'm using the
Nouveau driver on.

Sadly, this laptop panics on suspend if I am on the VT that Xorg is
running on at suspend time.  If I switch to VT 1 (log in as root and
suspend there, or even from somewhere else, say, ssh'd in) and then
suspend, it suspends fine and resumes fine and I can chvt back to the VT
with Xorg on it.

So the question is simply, how can I force suspending to chvt first and
then chvt back to the Xorg screen when resumed?

Cheers,
b.

Development and Contributions

James K. — 2012-01-27T12:28:47

Hello,

it seems like pm-utils is not being actively developed at the moment. I
have a few ideas I'd like to implement for pm-powersave, e.g., better
configurability or updated default hooks.

Are contributions welcomed? How would I contribute best?

Laptop with multiple batteries

E.S. Rosenberg — 2011-11-06T18:43:19

Hi all,
First off thanks for the great work.
Second I have a slightly annoying problem that I have been trying to
solve but so far to no avail.

My laptop has the option of having a second battery present, but I
don't have this second battery so it always reads as 0% as far as acpi
is concerned.
When I wake my system up from standby sometimes it will 'read' the
wrong batteries' status and say "golle gee I'm about to die! Let's
quickly hibernate."

I would like to somehow be able to interrupt this unnecessary
hibernate (something along the lines of shutdown -c but for
pm-hibernate), but so far I have not found how I can interrupt/cancel
the call to pm-hibernate.

Is there any mechanism at the moment, or a process I can kill?

Thanks,
Eli

pm-powersave does not work at start up and during session

Robert Orzanna — 2011-10-21T06:15:25

Hello,

I cannot determine why pm-powersave stopped working correctly but it is not
launched at start up or when the AC state is changed during the session.

The only case it is working is after suspend / hibernation.

The script I put in /etc/pm/power.d/powersave uses the settings from here:

http://crunchbanglinux.org/forums/post/110148/#p110148

Installed versions:

pm-utils 1.4.1-3 + kernel 3.0.1-1

Just let me know if you need more information.

Regards,

Robert

Disabling hibernation; determining what is requesting hibernation (workarounds for broken squeeze hibernation with backports kernels)

Thomas Shanks — 2011-09-22T02:52:13

pm-utils Maintainers-

On my system, resumption from hibernation does not work.  (See debian
backports mailing list thread here
http://thread.gmane.org/gmane.linux.debian.backports.general/7759 .)

I have configured the gnome power management settings for each user
account to suspend rather than hibernating for both low battery (which
certainly wasn't the cause this last time) and for idle.

Whether logged into gnome with these accounts or not, I am still
getting idle timeout hibernations.  This loses all my unsaved
work/state.

How do I disable pm-utils hibernation completely?

How do I find out what's requesting hibernation?
I am not seeing this information with debugging enabled as described
in the wheezy section on http://wiki.debian.org/Suspend (there is no
Squeeze section!).  Should I assume the wheezy section suggestions do
not work for squeeze?

And can you perhaps help with the original cause (broken resumption
from hibernation on 2010 Core i# Arrandale systems on squeeze with
either backports ke

Suspend work-around for HP DM1 3130 netbook

Frederic Bassaler — 2011-07-25T13:05:14

Hi all

After struggling a bit I found out how to make suspend-to-ram and
suspend-to-disk work 100% on my HP DM1 3130 netbook (AMD E-350 APU
based) :

the following kernel modules must be disabled :

SUSPEND_MODULES="hp_accel lis3lv02d"

Tested on several distros with kernel 2.6.37 and 2.6.38

I can only get suspend-to-disk to work properly with OpenSuse 11.4
though (pm-utils 1.4.1-5.9.1)


Maybe it should be added in the quirks database? Or it is a Linux
kernel related bug?

Do not override manual (sound) power managementconfigurations.

Paul Menzel — 2011-06-30T19:45:53

Dear pm-utils folks,


my message is regarding the reports #631791 [1] and #625606 [2] in the
Debian BTS. (You can get the mbox files running `bts show --mbox 631791`
with `bts` from the package `devscripts`.)

In my case [1] I want to use power management things, when the power
cable is plugged into my laptop. Therefore I pass `power_save=5` when
the sound module `snd-hda-intel` is loaded. But pm-utils executed by
upowerd overrides these settings.

Can the scripts be updated to check if there are manual or stricter
settings before and not to override them? Or just use set some settings
as default. I know in case of audio/sound going into “power save mode”
causes clicks sometimes. Maybe that is the reason not doing that by
default. But I could live with this.


Thanks,

Paul

I would start with the bug tracking systems of your distribution, in
this case Ubuntu. They should have a tool to help you report a bug like
`reportbug` in Debian.


Your report is missing crucial information. We do not know from our head
what software stack each distribution is running. So please include at
least the version of your Linux kernel and the version of pm-utils.

Furthermore, have you read the README files [1] or tried suspending
directly by using something like the following commands [2]?

        echo -n "platform" > /sys/power/disk 
        echo -n "disk" > /sys/power/state

Reading [1] you should find the command how to increase the debugging
level. You should post those here or to your bug report.

Notebook MSI MS-1632, since ubuntu 8.10 suspend mode (suspend) no longer 
works. When you harvest the button "Suspend" and he relaxed all that is 
necessary cuts off, as it should be off the screen, even a light bulb 
flashes that have peacefully asleep. But it is worth trying to wake him, 
as he had not even including the monitor hangs so much so that I can 
only hear wind noise coolers. Only the five-second button "Power" helps 
to turn it off. I was hoping that perhaps one day, all to recover, get 
better, get up to normal, and the grass will be greener and more people 
are happier and my laptop will wake up, but how wrong I was. Already 
more than a year, stood on my laptop all: Arch, SUSE, Ubuntu, Debian is, 
but none of them could help me. How can I be? Where to write bug 
reports? I want everything to be as before, and the green grass and

issue with resuming form pm-hibernate when on battery

Paolo Casaschi — 2011-02-04T11:25:34

Hello,

On my MSI Wind U100 netbook, I'm using a fresh install of debian
squeeze, using pm-utils 1.3.0 (no uswsusp as it's not available in
debian squeeze).
Everything with suspend/hibernate works fine (thanks!) with one
exception: resuming from hibernate when on battery power fails... what
happens is that I see the system booting, with the hard disk spinning
as when loading the hibernate image, but then suddenly the system
reboots to a fresh new start (with hibernate info of the previous
session lost).
On AC power, resume from hibernate works fine.

I already fixed a battery issue with the MSI Wind (battery reporting
wrong time left on unplugging the AC power, see
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=571161 for the issue
and the workaround).

Any suggestions how to fix this issue?
Any suggestion where to look to collect debug information?

TIA
