After an update of my debian, I lost :
And when I tried to apply new screen configuration I had :
GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service
Many references on the net, many solutions :
- reinstall cinnamon
- remove configuration file
- start /usr/bin/cinnamon-settings-daemon
All tried, none work.
Due to previous ressources and tests, I notice that when starting :
I had an error :
You can only run one xsettings manager at a time; exiting
After checking that is wasn't already started with :
ps -aef | grep cinnamon-settings-daemon
I perform a grep with :
ps -aef | grep settings
And I found that I had a gnome-settings-daemon running. Eurêka ! Gnome was my previous X manager.
So after a few checks :
sudo apt-get purge gnome-control-center gnome-settings-daemon gnome-control-center-data gnome-desktop3-data gnome-accessibility-themes
Restart, and all works.
