A little more information than what you have there will be required to help you get it done such as video card(s) make/model, amount of ram on it and the type of monitors you have their refresh rates both vertical and horizontal desired resolution of both the monitors and whether you want to use xinerama to have one large desktop or want to clone the display to both monitors. Oh and are you using the CD or a HD install if HD install which method??

The general procedure is boot then you kill of the X server so you can get a basic config file. To stop the Xserver once booted to the KDE login for a HD install use the CTRL and ALT and F1 keys at the same time or choose Console Login from the menu option in the login screen. Once to the command line login as normal user then use the su command to become root user and type in then enter key /etc/init.d/kdm stop to stop both the KDE display manager and the Xserver then use the command X -configure the screen should flicker a bit and you will be back at the command prompt with instructions on the command needed to test the new XF86config.new file that should have been created in the /root/ directory. Run the command and if you see a greyish screen on both monitors and can move the mouse then you have had success on the first try and only minor tweaking is need for the file. If not then more work will be required to get it going if you get the error that it cannot open the mouse and you are using a PS/2 wheel mouse the open the .new file and in the configured mouse section change the protocol from "auto" to "ImPS/2" and try again.


If it still does not work then you should be able to use the example below from my /etc/X11/XF86Config-4 along with the information for your card(s) in the .new file that was created to put together a working file.

Now you will need to change the refresh rates to the settings for your monitors in those sections and you should use the device sections from the .new file in place of the ones for my cards and you will want to start with just the three modes ( "1024x768" "800x600" "640x480" ) in the screen sections and then bump up the resolution if you want higher once you get a basic file going.
