This part is a little bit more tricky not that much ;-) First you have to find your gnome-vfs mime database. I found it on my system in /usr/share/mime-info/. There should be a gnome-vfs.keys in it. In this file you should find descriptions in various languages and the application and component assignents for every mime-type you see by default in your "File types and programs" dialog. I will use video/mpeg (without all those translations) as an example here: video/mpeg description=MPEG video default_action_type=application short_list_application_ids_for_novice_user_level=vlc,xmps,plaympeg,omsomi,mpeg_play,gtv short_list_application_ids_for_intermediate_user_level=vlc,xmps,plaympeg,omsomi,mpeg_play,gtv short_list_application_ids_for_advanced_user_level=vlc,xmps,plaympeg,omsomi,mpeg_play,gtv category=Video default_action_type ... is set to "application" which means that gnome will first try to use an application listed in the "application list" for handling this mime-type. short_list_application_ids_for_* Here you get a listing of applications assigned to this mime- type. I'm currently not sure, if this listing is complete or not. The pdf-entry: default_action_type=component short_list_component_iids_for_novice_user_level=OAFIID:GNOME_PDF_Control short_list_component_iids_for_intermediate_user_level=OAFIID:GNOME_PDF_Control short_list_component_iids_for_advanced_user_level=OAFIID:GNOME_PDF_Control short_list_application_ids_for_novice_user_level=acroread,gpdf,xpdf,ggv,gv short_list_application_ids_for_intermediate_user_level=acroread,gpdf,xpdf,ggv,gv short_list_application_ids_for_advanced_user_level=acroread,gpdf,xpdf,ggv,gv I thing its ok, to simple put xpdf as the first entry, so it becomes the major component to open pdf.
