No desktop background

[Nikola Yanev]

Binary package hint: gnome-settings-daemon

From 10 days or more GNOME desktop is having no wallpaper. When i try to set it i got this:

(gnome-appearance-properties:6838): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed

I am attaching a scr.shot so you can see what i am talking about

Hello Nikola Yanev

Would you be able to describe when exactly your desktop wallpaper had disappeared?

Could you also try to provide me with more info about what could have caused it, so I can recreate the bug

Thank You

Aaron

Hi,
As far, as i can remember it was 22.07.2009 or +- 1-2 days, ans i don't know what can be causing this, even with new account, i think that is gtk+ problem or gconf. If you need more info tell me.

lsb_release:
Distributor ID: Ubuntu
Description: Ubuntu karmic (development branch)
Release: 9.10
Codename: karmic
GNOME: 2.27.5
Linux: 2.6.31-4-generic

I shall get back to you if I can recreate this bug.

Thanks again

Hello Nikola

I have done some googling and have found another bug report

"https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/270744"

This bug report also shows:

GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed

although it is for a different process "network-manager"

I believe it is an underlying problem with 9.10

I will now try to recreate the bug

Thanks

Aaron

Hello Nikola

Could you please try to change the wallpaper, by using the EYE of Gnome image viewer

please tell me if you have already done this, or if this does not work

Thanks

Hello Nikola

dpkg -l gnome-settings-daemon

Thanks

Cannot Reproduce

unconfirmed for now

to be confirmed and released upstream by somebody else who can recreate the bug

[Nikola Yanev (gericom)]

Sorry for the delay ;)

dpkg -l gnome-settings-daemon: gnome-settings 2.27.5-0ubuntu

EYE: through terminal is the same, no change and the same error:
(gnome-appearance-properties:17222): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed

Hey Aaron,
i've just found the problem, it's coming from GDM, and to be more precise, when it is being installed and set, it doesn't check the key in gconf to use background in default!!!

/apps/gdm/settings-manager-plugins/background/active

and this key is set to FALSE by default ;)

I will fwd it to gdm maintainers [gdm_2.27.4-0ubuntu]

[Nikola Yanev (gericom)]

if you wanna recreate it, just uncheck this key and restart X, and you will see ;)

[Sebastien Bacher (seb128)]

there is no reason the gdm key should impact on the desktop where nautilus does the drawing and the key is set to true by edfault

[Nikola Yanev (gericom)]

i don't know either why, but since i found it i test it 3-4 times and the result is whan is to false-i have no wallpaper, and if set to true i got wall, but for testinf you should restart X between key seetings.
