Power Management Settings Are Not Applied / Retained

[tekstr1der]

Binary package hint: gnome-power-manager

Upon updating to gnome-power-manager (2.27.2+git20090729-0ubuntu2), settings found under System>Preference>Power Management are ignored after being set. After exiting Power Management, immediately opening it again will show the customizations just made, however, enacting a power event such as closing laptop lid will not only ignore the setting (does not suspend, though the option is selected), but will revert all settings back to default (check power management and see all settings reverted).

The same hold true for other settings such as pressing the suspend button. Even after setting it to suspend in Power Managment, it does nothing.

Also, clicking on the "Make Default" button appears to have no effect on any of this. All settings return to the defaults that ship with gnome-power-manager.

I tried to reproduce it, but couldn't. My settings are stored and still displayed after closing and reopening "Power Management". Everything is working fine here.

Could it be that your disk is full and the configuration thus cannot be saved to disk?

No, disk is not nearly full.

As I stated in the report, closing and reopening Power Management WILL show the customizations you have made. However, after a suspend or hibernate or reboot, the settings will revert to shipped defaults. My settings don't stick.

[Kai Jauch (kaijauch)]

Whoops, misread that, sorry. It would appear that the settings I make are honoured, though. If I set suspend on lid-close, it suspends fine (and the settings are still there after I resume), if I set it to do nothing, it does nothing.
However, rebooting makes them revert to default.

[Kai Jauch (kaijauch)]

Logging out seems to suffice in order to make the settings revert to default.

Thanks for the report. I can't reproduce this bug either (after suspending the settings are still the same). We can try some things to figure out what is causing this.

First, you can follow the instructions at:
https://wiki.ubuntu.com/DebuggingGNOMEPowerManager#Getting%20info%20from%20GPM
to run gnome-power-manager in verbose mode. When shutting down/resuming, see if any messages show up in the terminal.

Second, you can reset your gnome-power-manager gconf settings to the default. You can follow the instructions here:
https://wiki.ubuntu.com/DebuggingGNOMEPowerManager#Getting%20GConf%20values
You should back up your current gconf settings prior to resetting to default (there are instructions on how to back them up). Once they are reset to the default, see if the bug persists.

Okay, thanks for the debugging steps. This seems to be multiple issues. As Kai Jauch confirmed, the settings are indeed reverting to default after logout/login or reboot. That is issue #1 and is primary to the original bug report. To be fair, setting the option to suspend upon laptop lid closed has not been working for me in Karmic for some time. Worked fine with Intrepid and Jaunty. This compounds the issue, but here are some results from debugging:

1.)Reset power options to default with: $ gconftool --recursive-unset /apps/gnome-power-manager
2.)Launching Preferences>Power Management shows most drop lists are blank or say "Do nothing". Specifically, under the Battery Power tab, laptop lid closed has "Do Nothing" selected.
3.)$ killall gnome-power-manager
4.)$ gnome-power-manager --verbose --no-daemon
5.)close laptop lid, screen is blank
6.)open laptop lid, screen is displayed
7.)use the battery applet in panel to suspend, wait 30 second while suspended, resume from suspend
8.)terminal shows: (gnome-power-manager:3755): devkit-power-gobject-DEBUG: DBUS timed out, but recovering
9.)open Preferences>Power Management. Select Battery Tab, change option for laptop lid closed to suspend
9.)close laptop lid. screen is blank. no suspend. setting is ignored
10.)open laptop lid. screen is displayed.
11.)open Preferences>Power Management. Select Battery Tab, observe laptop lid closed option is now set to "Blank screen"

Any more info I could provide to help with this?

[Scott Howard (showard314)]

Thanks for the debugging info. We have some more commits coming
through over the next week (I believe 2.27.3-0ubuntu1 will be
officially released Monday on Ubuntu). Let's try to test again once it
is released. I'll leave it incomplete for now until we try against the
newest release.
