Problem encountered with x-windows in Fedora FC4

[Abe Drier]

I'll begin by mentioning my system works fine under FC3.  I currently
have a dual boot system with FC3 and FC4.

Trying to do the clean FC4 install using the windowing option resulted
in a white screen.  Retried the installation in text mode and the
installation completed successfully.  When the system booted, post
installation, the same white screen reappeared.  

Rebooted with "init 3" to come up in text mode.  Only one anomaly was
noted.  About every fifth keyboard entry results in the appearance of
one white square character in the center of the screen that lasts for
one keystroke.

Tried "startx" and was confronted with the white screen.  Switching to a
virtual console results in a confused mess of blue and gray box
characters.  Can log in successfully after which the screen has a blue
border with a working screen within the border.  The first few pixels of
the character that should be on the left edge are actually on the right
edge.  That is the first character of the line is split on the right and
left edge.

The "xorg.conf" configuration file is the same in FC3 and FC4.  So for
the moment I am perplexed.  The hardware is the same and the
configuration file is the same.  I have appended the configuration file.

Any suggestions would be most welcome.

(I have installed all the updates as of June 25 2005.  I can't execute
system-config-display from the console in that I get a white screen.
Was unable to locate xorgcfg or xorgsetup in Fedora as mentioned on the
x.org site.)
