I can add using terminal some applications to start at boot; I did follow 'backward' the idea given on XFCE wiki page:
http://wiki.xfce.org/faq?s[]=autostart
here we go:
1/ launch terminal (you will be in your home bt default, you even don't need to be root to do that) and check if you have Autostart dir in your Desktop directory
if it says 'nothing' means it is empty, then create the Autostart directory there:
if no error returned, you made a new dir
2) get the application you want to start: for that, you need to add a .desktop file (I beleive only this kind of file can be added). Thus you need to know what application you have, so you will list them
Code:
ls /usr/share/applications/*.desktop
you will get a full list of your desktop file from which you are able to launch associated application (you can edit with mouepad a .desktop file to see how it is made).
3/ copy your .desktop file (I did it with Skype) into the dir you created above:
Code:
cp /usr/share/applications/skype.desktop /home/user/Desktop/Autostart/
now, you have a copy of tis skype.desktop in your 'own' autostart dir.
You can check that this command updated the autostart info in launching the xfce4-autostart-editor (to check, use the search bar on your desktop, type autostart, and double click on 'xfce4-autostart-editor'; you will see the Skype application listed with its original comment.
Remark about the check above: I did it after I rebooted my AA1, you might do the same too if you wish to check everything is ok.
hope it helps,
within
PS: I am NOT a linux guru, closer to a n00b, but I enjoy playing with commands when I can find some good explanations around, and when I get the result I wish... and sometimes it takes looooong time to get a working result
