[SLUG] X Windows

Hi Mark,

Your XF86Config file is corrupted in some way hence the parse error "(EE) 
Problem parsing the config file" when you try and start X. Also the error 
"Fatal error: no screens found" is saying that you don't have a screen 
section in your config file and this is true looking at it.

XF86Config files are always all text and should be human readable throughout 
(even it you don't understand the contents).

As an example here is my working XF86Config file:

### FILE BEGINS

	# Uncomment this to cause a core dump at the spot where a signal is
	# received.  This may leave the console in an unusable state, but may
	# provide a better stack trace in the core dump to aid in debugging

	# This allows clients to receive this key event.

### FILE ENDS

This obviously won't work for your graphics card/monitor configuration but at 
least it gives you an idea of what to expect.

It may be worth trying to create your XF86Config file with the command line 
tool, namely xf86config, if you have not already tried this. Just type 
'xf86config' and answer the questions. When finished look at the resulting 
XF86Config file via a straight text editor.

Also something to watch out for with XFree86 version 4 is that it will pick a 
config file called XF86Config-4 in preference to an XF86Config if the file 
exists so beware; ensure that is not one of these laying around in your 
/etc/X11 directory.

Hope this helps,

Kind regards,

Paul.
