Window manager warning: Fatal IO error 104

[jackson byers]

an f10 install, minimum defaults from purchased dvd.
Only sda1 is formatted by installer; /boot not a separate partition.
Grub initially installed into 1st sector of sda1, left mbr alone.
Later Grub also installed into mbr of sda.
Currently booting into level 3, experiencing trouble with X-server

no help, nothing to update

yes, it is.

Adding just the Monitor section seemed to work, at least initially:

------start of xorg.conf------------------

----------end of xorg.conf---------


Now seems caught in some sort of mix of errors from
X server, Window manager, startx:

[root at localhost ~]# system-config-display -v

it says "X server started successfully"
but then  " Fatal IO error 104 (Connection reset by peer) on display ':17.0'."

With that error, it may be silly to try startx, but i did anyway:

]# cat startxlog
[root at localhost ~]# startx
xauth:  creating new authority file /root/.serverauth.3606
xauth:  creating new authority file /root/.Xauthority
xauth:  creating new authority file /root/.Xauthority


Fatal server error:

        and start again.

rm  .X0-lock
then another
startx

# cat startxlog2

[root at localhost ~]# startx

why no current(may 10)  Xorg log?

no errors seen from this setup log

I have  done some googling on the Window manager error 104 but so far
no help to me.

Further steps?
