+   When the desktop restores the frame and window configuration, it
+uses the recorded values of frame parameters, disregarding any
+settings for those parameters you have in your init file (@pxref{Init
+File}).  This means that frame parameters such as fonts and faces for
+the restored frames will come from the desktop file, where they were
+saved when you exited your previous Emacs session; any settings for
+those parameters in your init file will be ignored.  To disable this,
+customize the value of @code{frameset-filter-alist} to filter out the
+frame parameters you don't want to be restored.
