I'm trying to manually tell x windows (or would it be gnome ...) which monitors are attached to my laptop since it doesn't detect them properly, however, I have a few questions.

First, how do I know what to use as the Identifier in the Monitor section of the xorg.conf file? Is it just any name I choose? Or does it have to be something specific? If it's something specific where do I find this info? If it's anything I choose, how do I tell it which monitor is which since I need to specify two monitors (internal display and external monitor)?

Thanks,
Harry

Information for manually configuring xorg in hardy is here (https://help.ubuntu.com/community/XORGHardy) but ATI cards are not mentioned at all and from your previous post I think that's what you have.
A more general guide which doesn't appear to handle you situation is here (https://help.ubuntu.com/community/Video).

Thanks but those links talk mostly about configuring the driver or device part of xorg.conf ... my concern I'm pretty sure is mainly the Monitor part.

Also another question I have is, how do I specify which resolutions the monitor can support.

Thanks,
Harry

There's a "monitor" section in xorg and the modelines list the rez & more. See mine below for example:
