[Newbie]XF86Config problems

[Jon Chalk]

Hi all.........   I ran XFree86 -configure and copied the resulting XF86Config file to /etc/X11.  The startx command results in a screen containing vertical coloured lines which then flicks to an error message box (unreadable text) containing two buttons - try again and continue.  Ctrl-Alt-Backspace gets me back to a prompt.  Upon further inspection, the newly created XF86Config file contains no references to modes or modelines - is this normal for XFree86 4.2......??   Any guidance to the next step I should be taking would be much appreciated.   Thanks, Jon.
