Firstly apologies for not using send-pr. My machine is a little bit broken. Every time I try and run the command 'X -config xorg.conf.new' I get a page fault. I have tried the text interface to create the test configuration as the one which automatically generated didn't look too much like the one I was using on rel 5.3 I have spent some time going through the manuals online to find out how to produce this output which I hope is useful. If there's anything else you need pls drop me a line. Hope I'm not doing anything stupid.
regards,
henry
