On Ubuntu 12.10 64bit I additionally installed kubuntu-desktop. I installed dropbox in Unity to use it there with nautilus. In Kde this is not the wanted behavior so I installed the dropboxd - Daemon and enabled it to autostart in KDE. But the nautilus-dropbox applet is always started in addition to the daemon.
How can I make sure that there is ONLY the dropboxd running and NOT the nautilus-dropbox when I use KDE and When using Gnome I llike to use nautilus-dropbox?
plz note that there is no setting for nautilus-dropbox in KDE autostart applications!
Maybe there is a way to install two versions and make sure only the right one is started with each desktop environment?
This is from a quick Google search and is a bit old, but http://ubuntu-tutorials.com/2010/01/17/install-dropbox-on-kubuntu-kde-without-nautilus/ covers how to install Dropbox and get it working w/o all the dependencies and the notifier running. Might still work for you.
Right click in the applet,
Preferences/General
and disableStart Dropbox on system startup
.
