I'll stick my neck out and say the archive that you would have unpacked should be in another location.
Code:
sudo mv .dropbox-dist/ /opt/dropbox-dist
I'll also stick out my neck and say that it shouldn't be
autostarted like
they want you to set it up...for
convenience. But there is no (easy) choice.
Every time you boot it will start. It places the application in your autostart queue. (~/.config/autostart/dropbox.desktop)
However, by placing a menu entry in
Internet you will have the ability to launch the application after you have turned it off.
Code:
gksudo medit /usr/share/applications/dropbox.desktop
and paste in
Code:
[Desktop Entry]
Name=Dropbox
GenericName=File Synchronizer
Comment=Sync your files across computers and to the web
Exec=/opt/dropbox-dist/dropboxd
Terminal=false
Type=Application
Icon=/opt/dropbox-dist/dropbox-lnx.x86-3.0.4/images/hicolor/16x16/status/dropboxstatus-logo.png
Categories=Network;FileTransfer;
StartupNotify=false
Save and exit. The menu entry appears
