This page is intended for explaining the internal architecture of GNOME as well as sharing GNOME hacks.
Changing Required Components
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.UsbGuard 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.UsbGuard 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
org.gnome.SettingsDaemon.UsbGuard- 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. Can be turned off..
org.gnome.SettingsDaemon.Wacom- Implements functionality for tablets (assumption.) Can be turned off.
org.gnome.SettingsDaemon.SmartCard- Implements smart card support (assumption.) Can be turned off.
