Temporarily not load U1 at startup

[RogerDavis]

How do I TEMPORARILY stop Ubuntu One from loading at startup while I test something?

And the flip side - Once done testing, how do I make it start up again?

Go to "Startup Appliations..." and uncheck Ubuntu One. Once done testing you can simply check it back. If you don't have U1 listed in your startup apps open a terminal and run the following line:

sudo sed -i 's/NoDisplay=true/NoDisplay=false/g' /etc/xdg/autostart/*.desktop

Some other apps that are hidden by default will also appear in "Startup Applications...".

OK, that answers my original question, but after I entered the line into Terminal it showed MANY programs. Were these all running in the background before, and I just didn't know it?

Yes, they are all startup programs that get launched on login.
