Configuring Dual Screens

[Greg Lindstrom]

Hello,

I have decided to convert my machine at work to Ubuntu (I have run
Ubuntu on my laptop for over a year and have been wanting to make the
change for a while).

I have 2 Hanns-G 19" monitors and a ATI Radeon 7k graphics card in my
system.  I went to "Screen Resolution" and noticed the two monitors
represented in the screen, then unchecked "clone screen" and turned
off my second screen.  This worked fine.  I cannot, however, get my
second screen to work.  I thought I would be able to turn it "on" with
the same resolution and refresh rate as the primary screen, but it
just won't work. I can set it as a clone and both screens show the
same information.

I have read through various posts on the matter and see that many
people go into their xorg.conf file to set up monitors, screens, and
devices.  Is that still necessary with 8.04?  I'm thinking since I see
the screens represented in the GUI I should be able to do this without
editing files (I'm OK with editing them, I just want to find out if
it's still required).  If I have to edit files, how do I find out the
values to use in the "device" section for my particular monitors and
video card?

Thanks for your time and attention,
