Start using it
No, serious, you can try startx
to get to a GUI.
However, I would assume that you should get a GUI out of the box, so something might be wrong with your computer. Did you read the user manual (when I bought an Acer One a little while back, it came with some instructions).
please.. someone help me immediately thanx !
That sounds very demanding and is usually not appreciated. Everybody here does this in his/her spare time and we usually don't see your problem as something urgent that needs immediate attention.
