Have you logged in?
If not log in as root - you dont\' need a password, then type startx to start the GUI.
Step by step -
1. type \"root\" - without the quotes - then hit enter
2. hit enter again when it asks for password
3. type \"startx\" - without quotes - then hit enter
4. wait while the gui starts up.
Not to be rude, but if you can\'t work out how to login then pdaX may not be your cup of tea - try something a little more user friendly like the cacko rom.
