Unable to start the settings manager ‘gnome-settings-daemon

Problem description

 

After logged in or went to ” System -> Preferences -> Appearance“, you saw the system give the following error message:

Unable to start the settings manager gnome-settings-daemon.
Without the GNOME settings manager running, some preferences may not take effect. This could indicate a problem with Bonobo, or a non-GNOME (e.g. KDE) settings manager may already be active and conflicting with the GNOME settings manager.

1. Changing session files

2. At the login screen, go to Option -> Select session.

 

Select gnome (2.) and make it your default.

 

3. Of course, reinstall the OS.

 

But, none of them worked for me (did not try method 3, 🙁 ).

The method that worked for me is:

 

Solution

 

Edit /etc/network/interfaces, make sure the first two lines are:

 

 

Reboot.
