This page is intended for explaining the internal architecture of GNOME as well as sharing GNOME hacks.
GNOME Components
GNOME components are parts of GNOME (part of gnome-settings-daemon that are spawned by gnome-session when it starts.
They provide services inside GNOME.
Disabling
The file /usr/share/gnome-session/sessions/gnome.session contains a line at the bottom of the file starting with RequiredComponents=, which lists services that GNOME will expect to be able to start. If it can't start one of these components, it will display a fatal error (sick computer) at startup and GNOME will not start.
Some of these so-called 'required' components can be turned off. For example, org.gnome.SettingsDaemon.UsbProtection can be
turned off. To do this, first remove the reference to this component from the RequiredComponents line in the gnome.session file. Then, move /etc/xdg/autostart/org.gnome.SettingsDaemon.UsbProtection to a backup location, such
as /root. The next time you log into your GNOME session, you will see that the gsd-usbguard process is no longer
running, yet GNOME started just fine (since this component is no longer marked as 'required'.)
Components List (Incomplete)
org.gnome.SettingsDaemon.UsbProtection- This component 'guards' USB ports and informs you when someone has attached a USB device when your computer is asleep. It also does some disabling of USB devices when the system is asleep. Daemon name is
gsd-usbguard. Can be turned off (see Disabling). org.gnome.SettingsDaemon.Wacom- Implements functionality for tablets (assumption.) Can be turned off (see Disabling).
org.gnome.SettingsDaemon.SmartCard- Implements smart card support (assumption.) Can be turned off (see Disabling).
org.gnome.SettingsDaemon.Housekeeping- Provides a service to clean out the desktop thumbnail cache once daily.
org.gnome.SettingsDaemon.ScreenSaverProxy- Implements a dbus interface for
InhibitandUninhibit(presumably to allow inhibiting of the screensaver.) org.gnome.SettingsDaemon.Sound- Daemon is
gsd-sound. Monitors for change of theme and caches sound samples in the theme. org.gnome.SettingsDaemon.Dummy- This appears to be a component that can be used as a featureless replacement for another plugin. For example,
gdmrunsusr/libexec/gsd-dummy --dummy-name=org.gnome.SettingsDaemon.Smartcard.
