Comment 5 for bug 284309

Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here. Thanks for taking the time to make Ubuntu better!

In Intrepid 8.10, Xorg uses an autoconfiguration that no longer writes the xorg.conf file, to the best of my knowledge. So, yes, I think that not having xorg.conf is normal under auto detect.
