Ok i tried Fedora Core 6 Live CD on a DELL optiplex gx260 and it says "Failed to start the X server (your graphical interface)" It is likely that is not set up corectly. Would you like to diagnose blah blah."

So i chose yes and yes until it prompted me to enter the root password. What is the rrot password guys? and i'm assuming the the error is maybe my monitor or video card? am i right? what should i do?
