How do I prevent Dropbox from being automatically added to the autostart list after launching it?
Command-line option might also work:
$ dropbox autostart n
From:
$ man dropbox
Click on the icon, preferences, then uncheck the box "Start Dropbox on system startup".
By default, dropbox will start automatically at login. The update-rc.d command is not concerned here. (/etc/rc*.d/directories don't contain dropbox). There is no service "dropbox" (/etc/init.d don't contain dropbox)
If you have installed dropbox with ".deb" package (sudo dpkg -i dropbox.deb), then you may have the executable /usr/bin/dropbox
To disable the dropbox auto-start :
/usr/bin/dropbox autostart n
To enable the dropbox auto-start :
/usr/bin/dropbox autostart y
