Can you rephrase your question? What exactly is happening and what hardware are you using (video card wise)?
Temporarily, so you can run startx, I would try loading GRUB on boot and enter the edit mode (It will specify at the bottom of your screen the keys to strike to enter this mode, newest version of Grub is TAB).
after vga=761 add: nomodeset
This should allow you to enter startx.
Also, are you using KDE or Gnome?
