There was an error starting the GNOME Settings Daemon.

Some things, such as themes, sounds, or background settings may not work correctly.

The last error message was:

The name org.gnome.SettingsDaemon was not provided by any .service files

GNOME will still try to restart the Settings Daemon next time you log in.

是不是更换过主题？有些主题有bug的。换回去试试。
