How do i get back into KDE?

[dtk]

I am a noob to linux plz help me.
After you press Alt+Ctrl+F2 (cant remember what it's called) how do you get back into KDE? ive tried typing "startx" but it tells me:

Fatel server error:
Server is already active for display 0.
if this server is no longer running, remove /tmp/.X0-lock and start again.

After logging out of Ctrl-Alt-F2 with Ctrl-d press Ctrl-Alt-F7 (could be F5 with the cd).

Thanks alot.
