I've finally solved this issue, it seems that it is somehow connected to the gnome window manager being set to metacity. I was able to customize the sound effects by deleting this folder:
~/.gconf/desktop/gnome/applications/window_manager then logging out and back in again and now everything is back to normal. this is what changed in my case in the %gconf.xml file <?xml version="1.0"?> <gconf> <entry name="current" mtime="1233465282" type="string"> <stringvalue>/usr/bin/metacity</stringvalue> </entry> <entry name="default" mtime="1211261856" type="string"> <stringvalue>/usr/bin/metacity</stringvalue> </entry> </gconf> was changed to : <?xml version="1.0"?> <gconf> <entry name="current" mtime="1233466103" type="string"> <stringvalue>/usr/bin/compiz</stringvalue> </entry> <entry name="default" mtime="1233466103" type="string"> <stringvalue>/usr/bin/compiz</stringvalue> </entry> </gconf> I hope this helps someone ! -- gnome-sound-properties setting to disable login sound not honored https://bugs.launchpad.net/bugs/277203 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
