So ck-history --seat ... for a dynamic seat will give the merged history of all the transient seats that used that seat-id in the past. :-( >> It appears that there is some persistent state associated with seats via >> seat-ids.

If gdm uses the per-seat history to sort/populate the face browser, that list will be relatively random for dynamic seats. - J?rg -- Joerg Barfurth phone: +49 40 23646662 / x66662 Software Engineer mailto:joerg.barfurth at sun.com Desktop Technology http://reserv.ireland/twiki/bin/view/Argus/ Thin Client Software http://www.sun.com/software/sunray/ Sun Microsystems GmbH http://www.sun.com/software/javadesktopsystem/
