They are the settings you set with xfce4-display-settings, they don't
reflect the current hardware state (if a display isn't plugged, its
settings won't be applied anyway).

"Default" is applied at startup by xfsettingsd and set by
xfce4-display-settings.  "MinimalAutoConfig" is only set by the minimal
dialog (xfce4-display-settings -m). This was done to allow people to set
a temporary config with the minimal dialog (e.g. when a projector is
plugged) without affecting the default config.

I don't use the graphical Xfconf editor, but I guess this is related to
kiosk mode (you can lock channels and properties system-wide to prevent
users to change them). But that's only for Xfconf, if you change the
resolution with xrandr, it still works, and xfsettingsd won't revert it
automagically unless you reapply the scheme.

Ok, but this bug ("sometimes xfce4-display-settings fails") won't
magically get fixed by itself. ;-)
Do not hesitate to report a bug on bugzilla.xfce.org about what you
tried to do when it failed and what's your randr config and your graphic
driver.
