How to start nautilus-dropbox with Gnome and kfilebox with KDE?

Question

I use Ubuntu/Kubuntu 12.10 with KDE 4.10 and Unity, switching beetween the two depending on what I intend to do.

My question is:

How can I make sure that

• the package nautilus-dropbox is only started when I login into Unity
• and when logging in into KDE only kfilebox is started?

Answer 1

Sessions are your friends.

Basically add those apps to your sessions (collections of app that each desktop env, will start after you login).
