Problems with running Kubuntu from CD

[1gnition]

I downloaded Kubuntu 9.04. I burned it and inserted it to the CDROM. I booted from CD. In the first menu that appears I choose: "Try Kubuntu without any change to your computer". After A while I see the terminal on full screen and that's all. The desktop and the environment won't start. I tried some commands to bring up the desktop and the GUI but there is nothing. Is it a bug? What should I do?

Did you run the option to check cd for defects at the initial screen? How fast did you burn the CD?

if you type startx do you get some error about "no screens found"
what is your video card?

1. I did run this test. The result was that the CD was fine.
2. I burned the CD on x48.

1. I type startx and it brings up Kubuntu. Everything was fine except that I got a message that "The desktop process died unexpectedly".
2. I have nVIDIA GeForce 7600GT.

Why haven't it been brought up automatically without me typing startx? What seems to be the problem?

I recommend you burn it at 4x or slowest speed possible.
