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
