`screen` : | a GnomeRRScreen
`error` : | location to store error, or `NULL`
Returns : | TRUE if the screen's configuration changed; otherwise, the function returns FALSE and a NULL error if the configuration didn't change, or FALSE and a non-NULL error if there was an error while refreshing the configuration.
