I run Ubuntu 12.04.1 LTS x64 in VirtualBox. After one very unfortunate misclick (reset saved state instead of load saved state) I got a very annoying problem.
Almost all applications (unity, synaptic, gedit, etc.) print on start:
Using the 'memory' GSettings backend. Your settings will not be saved or shared with other applications.
And all GUI settings reset after reboot.
$ GSETTINGS_BACKEND=dconf dconf-editor
(dconf-editor:2353): GLib-GIO-WARNING **: Can't find module 'dconf' specified in GSETTINGS_BACKEND
GLib-GIO-Message: Using the 'memory' GSettings backend. Your settings will not be saved or shared with other applications
/usr/lib/x86_64-linux-gnu/gio/modules/libdconfsettings.so is present.
What I tried (and it didn't help):
sudo apt-get install -f --reinstall dconf-tools libdconf0 libdconf-dbus-1-0 dconf-service
- Build dconf-0.5 from sources and
- Create empty user profile and start programs there
I have to keep current Ubuntu installation so a complete reinstall is not an option for me.
How can I fix it?
