mate-power-manager power button settings ignored

[Paddy Launch]

Release: 13 (maya)
Edition: MATE 64-bit

Hardware: Dell Latitude D830 laptop

Steps to reproduce:

1. Power Management Prefs: General -> Actions -> When the power button is pressed: SUSPEND
2. Close mate-power-manager
3. Press Power button.

Expected result: Machine suspends

Actual result: Machine shuts down.

Even when the power button action is set to "Ask me", it still shuts down. On one occasion, a list of options came up, but the machine shutdown before there was an opportunity to select any of them.

Additionally apport-bug told me that 'mate-power-manager' is not an official Linux Mint package. And also, mate-power-manager does not appear to be accessible from Control Centre (only from the power management icon in the panel).

I have this problem as well -- I don't know if one of the following "non-standard" installation parts made this bug happen for me but just in case: I'm running a fresh Mint 13 Mate 64-bit installed from DVD image, but my previous home partition (from Mint 11) was left intact for the new system. I also used MintBackup to save my packages list from Mint 11 and re-install the corresponding packages after the upgrade. Also I am running compiz.

Release: 13 (maya) [Fresh 32-bit install, not an update/upgrade]
Edition: MATE 32-bit
Hardware: Samsung NC-10 netbook

 I'm having a similar issue as Reported by Paddy Launch. Instead of setting 'Suspend', I'm using 'Ask me'.

Specifically:
Power Management Preferences | General (tab) | Actions | 'When power button is pushed:' --- Setting is set to 'Ask me'.

Every time, pushing the power button causes the machine to immediately shutdown.

I have Linux Mint 13 fresh install to clean disk and I'm also suffering from this bug the same way as was described before.

[Hans-Christoph Steiner (eighthave)]

I found the issue, it is in the script /etc/acpi/powerbtn.sh. The script looks to see if there is some kind of daemon running that will handle the power button event. If not, it just calls "shutdown -h now" directly. I fixed this by adding one line to the /etc/acpi/powerbtn.sh script (PMS="$PMS mate-settings-daemon"):

[ -r /usr/share/acpi-support/power-funcs ] && getXconsole
PMS="gnome-settings-daemon kpowersave xfce4-power-manager"
PMS="$PMS guidance-power-manager.py dalston-power-applet"
PMS="$PMS mate-settings-daemon"

[Simon741 (simon-okko)]

Works for me. Thanks Hans-Christoph.

[SamiR (sami-m-rantala)]

Hans-Christoph's solution works for me, too. Thanks!

[isaac (isaacgallegos)]

This bug is also in the 32bit edition of LinuxMint 13 Mate

[Craig Hatch (h958081)]

Hans-Christoph's fix works for me on a Lenovo T500. with the 64bit edition

[Jay Carlson (jaycsoftdove)]

Brilliant! Thanks to Hans-Cristoph

[Luis A. Serrano (lserrano-cortez)]

I love you so much for this solution xD
I spent a lot of hours finding possible answers ..

Working on Linux Mint 13 Mate x64; my laptop is a Lenovo G475.

[Paddy Launch (paddylaunch-deactivatedaccount)]

It seems that quite a few things have been broken by code still
referring to 'gnome' instead of 'mate'.

[Tanco (smarkovik)]

works like a charm.. thanks

[Jeshurun (sjeshurun)]

Awesome thanks, that worked for me as well. Alienware M14x R2, Mint 13 x64.

[Martin Habovštiak (martin-r24)]

Works for me, thanks!
BTW how can I setup "Do nothing" on button press? (If I accidentally press button I don't want my computer to display any dialog)

[Pistolpete (petervanbouwel)]

This patch works great. Does exactly as told on a Dell E6520.

If you want the do nothing there are instructions on http://www.linuxandlife.com/2012/07/how-to-customize-power-management-in.html

[stone (sfystone)]

Thanks to #4. And I'd like to share my work around on Fedora 17.

Modify /etc/acpi/actions/power.sh

Add one line of $2 ~ /mate-power-manager/ ||
And it becomes like:

# Check that there is a power manager, otherwise shut down.
[ "$uid_session" ] &&
ps axo uid,cmd | \
awk '
    $1 == '$uid_session' &&
        ($2 ~ /gnome-power-manager/ || $2 ~ /kpowersave/ ||
         $2 ~ /xfce4-power-manager/ || $2 ~ /\/usr\/libexec\/gnome-settings-daemon/ ||
         $2 ~ /mate-power-manager/ ||
         $2 ~ /kded4/ || $3 ~ /guidance-power-manager/) \
                { found = 1; exit }
    END { exit !found }
' ||
  shutdown -h now

[stone (sfystone)]

Well.... I never know this forum is with no edit function.
The #16 work around is not working. The added line should be $2 ~ /mate-settings-daemon/ ||
But the deamon is not running(Should be a bug). So the change make computer do nothing upon power button under Mate.

[maksim (m.arutyunyan)]

Hi,

Still have this bug in Linux Mint 14 MATE 32bit (solution from post#4 works well).

Regards.

[Karthik T (sir-nigel-loring)]

Hans-Christoph's fix works works perfectly for me as well, thanks!

[asettico (asettico)]

The patch at #4 work also for Linux Mint 14 Nadia 64 bit.
Thanks!

[Karthik T (sir-nigel-loring)]

Dissapointed to see the problem has not been fixed in Linux Mint 14.. The mentioned fix still works.

[HXT (voegel4711)]

Post #4 works really fine.. For me it's on Mint 13 32bit.

@Developers: Why didn't you fix this bug allready? The mentioned workaround is no more than adding the correct parameter to a script which is triggered when pressing the PWR-Button, as far as I understand.

[Miroslav (dzundam-deactivatedaccount)]

I'd like to add, that similar patch as per post #4 fixed the "suspend" button on my laptop.

mate-power-manager sleep-button settings were ignored, laptop always went into sleep
after pressing sleep-button, despite I set 'nothing' in the action.

I fixed this by adding one line to the /usr/share/acpi-support/policy-funcs script:

PMS="gnome-power-manager kpowersave xfce4-power-manager"
        PMS="$PMS guidance-power-manager.py dalston-power-applet"
        PMS="$PMS mate-power-manager"

It seems acpi in Mint 13 (Mate) is not configured with mate-power-manager in mind.

I haven't dug, whether this has been fixed in upstream acpi.

[martywd (martywd)]

I hadn't checked back here in quite a while but as noted above I have found too this is still an issue in LM 14 MATE 64-bit.

I didn't know about the added scripting option(s). Instead I've been editing/commenting out the last line in the /etc/acpi/powerbtn.sh file like so:

#/sbin/shutdown -h now "Power button pressed"

Save file/exit.

This simple mod has worked for me in both LM 13 and LM 14, preventing an immediate shutdown from a power button press and instead yielding a prompt for further action(s).
.

[Miroslav (dzundam-deactivatedaccount)]

to Martywd: the acpid and acpi-support isn't configured with mate-power-manager
in mind, thus the editing of the acpi config files is needed. Simply acpi scripts take
over the computer control, because they 'think' there is no other power managing
application running.

You can try the step from post #23, it fixes the acpi.

The other solution is to simply uninstall the packages acpid and acpi-support.
In my case the system started to behave normally and without any negative
side effects.

Your edit of the script is simply the another way to get the desired behaviour.

[martywd (martywd)]

Ok, forget my mod in comment #24. Hans-Christoph's suggested fix in comment #4 seems the more appropriate solution to this push power button / immediate shutdown issue and for me it solves the issue in both LM13 and LM14.

@Miroslav
Your suggested mod in comment #23 didn't change the press power button/immediate shutdown issue for me whereas Hans-Christoph's suggestion did.

But, Miroslav, your suggested mod of the '/usr/share/acpi-support/policy-funcs' has fixed another 'Suspend' issue I've been having on a recently acquired laptop (LM14 MATE 64-bit). The problem was, when suspending the laptop using the Fn+... combo keys the laptop would suspend. But on the next press of the power button (or re-opening of the laptop's lid) to wake the laptop back up, the login screen would light up, but immediately return to suspend resulting in a required second press of the power button. Once the display came up a second time, the laptop would remain powered on thus allowing login, etc.

This was only happening when the laptop was suspended using the Fn+... keys. I.e., if I simply pressed the power button (or clicked 'Menu Button | Quit' in the MATE menu) and then clicked the 'Suspend' button at the gui popup prompt, the laptop would suspend and with another press of the power button the laptop would power up and remain powered on.

Adding the'PMS="$PMS mate-power-manager" line to the /usr/share/acpi-support/policy-funcs' script as per your instructions in comment #23 has fixed this suspend using the Fn+... keys issue. Now when resuming from a Fn+... key press suspend, I haven't had any further false starts.
.

[Miroslav (dzundam-deactivatedaccount)]

@Martywd: you are right, mod from post #4 fixes the power button behaviour and mod from post #23 the suspend button behaviour.

Both mods are basically the same, only located in the different acpi scripts (one responsible for acpi shutdown and another for acpi sleep). Both scripts by default don't check for the presence of mate-power-manager running as they should, after the mods they do.

[Fabio Amaral (fabiom2)]

Fisrt at all, thank you very much to Hans-Christoph. (#4), the solution is simply and perfect. But this is still a issue in Linux MInt 15 MATE (both 32 and 64bits tested).

[Simon741 (simon-okko)]

I confirm that the problem is still present in Linux Mint 15 (and that Hans-Christoph's solution still works.

What could we do that this gets committed?

[Mauro (mauromol)]

The same problem applies to Linux Mint 16 KDE (64-bit). Can this be fixed?

[Mauro (mauromol)]

I think this bug is fixed in Linux Mint 16 for Mate (the check for mate-settings-daemon is present in /etc/acpi/powerbtn.sh), so I think this bug should be closed.
Instead, it still affects Linux Mint 16 KDE. I opened bug #1306912 for this, with the workaround I've found to fix the problem. Is there someone from Linux Mint reading here?
