Window manager warning: Fatal IO error 104

Sunday, 10 May 2009

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

 Many people on this list will have much greater expertise than I to
 solve your X problem. My *non-expert* suggestions are that you could: 
...
 1) yum update xorg-x11-drv-mga 
no help, nothing to update

...
 5) Look at the xorg.conf of your previous Fedora install for ideas,
if
 it is working ok on the same hardware. 
yes, it is.

...
 6) Try to create your own xorg.conf based on it and/or your tmp
ones.
 Your xorg.log seems to be using the correct driver but reports "No
 monitor specified", you could try adding a "Monitor" block to your
 xorg.conf, particularly if you have one that works for your previous
 Fedora. I've had to do similar in the past. 
Adding just the Monitor section seemed to work, at least initially:

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

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

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

[root@localhost ~]#

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@localhost ~]# startx

xauth:  creating new authority file /root/.Xauthority
xauth:  creating new authority file /root/.Xauthority

Fatal server error:

        If this server is no longer running, remove /tmp/.X0-lock
        and start again.

rm  .X0-lock
then another
startx

# cat startxlog2

[root@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?
