I always use only one account on my computer.
I do have a lot of programs in startup and I need them all. The problem is that they take some time to load (for example eclipse).
is there any way to do auto-login on the account and lock screen so no-one else can use my account?
Use gnome-screensaver-command -l right after the list of programs you load.
It will lock your screen when you run it.
Maybe use a utility like preload to load the applications into memory for you prior to login:
sudo apt-get install preload
Then Eclipse, Firefox and friends should start up in a jiffy. I haven't tried it myself, though, and you should probably read up on how it works and how to configure it.
