graphical desktop problem
 

I Have reently installed red hat linux om my computer.The distribution I have has both GNOME and KDE graphical desktop environments.I realized that in the
start menu it had the option to switch to a text based environment so I did thinking I could easily revert back to a graphical environment.But I cant because I dont know the right command. can someone help me or if you dont understand tell me. any help is much apreciated.

$ startx
