AddScreen/ScreenInit failed for driver 0

[Geoff Hacker]

Hi all,

I switched from using XFree86 to Xorg when I switched from FC1 to FC2.
Now I cannot start X. The screen simply goes black and stays that way
until I Ctrl+F4 out of it back to the shell. Below is the redirected
output from the startx command:
