Dual head display issues with Warty

[kruppe]

Hi

I'm totally new to Ubuntu as I've been exploring SuSE for quite a bit
since last year.

Finally decided to make the move with Kubuntu release last week.

My question is with regards to a dual head setup for an Nvidia Geforce
4 Ti 4200 AGP 8x with 128Mb. 

With the Windows drivers, the configuration was quite simple.

I have an AOpen 19" CRT 85Hz 1600x1200 capable and a Mag XJ796 capable
of the same.

I understand that I need to change my conf file for x.org but I've
tried that - I get output on the main display, but the second display
gives me odd 'Atari-like' characters and a headache-deluxe refresh
rate.

I've never played around with this, so please bear with me.

The x.org mutilated :-#  file follows:

Code:
--------------------
    
  # /etc/X11/xorg.conf (xorg X Window System server configuration file)
  #
  # This file was generated by dexconf, the Debian X Configuration tool, using
  # values from the debconf database.
  #
  # Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
  # (Type "man /etc/X11/xorg.conf" at the shell prompt.)
  #
  # This file is automatically updated on xserver-xorg package upgrades *only*
  # if it has not been modified since the last upgrade of the xserver-xorg
  # package.
  #
  # If you have edited this file but would like it to be automatically updated
  # again, run the following commands:
  #
  #   cp /etc/X11/xorg.conf /etc/X11/xorg.conf.custom
  #   sudo sh -c 'md5sum /etc/X11/xorg.conf >/var/lib/xfree86/xorg.conf.md5sum'
  #   sudo dpkg-reconfigure xserver-xorg

Could you please point out where I am going wrong? 
Am I missing something?
How does 3D accel affect the setup?
Can you run different resolutions without enabling the virtual desktop
size?
How would multiple heads word with my existing 8 desktop configuration
in KDE?

Thanks in advance.  ;-)
