HowTo: DualHead on NVidia - Fedora 9

[Alecfyz]

NOTE: there are not any questions. It`s just "HowTo" about dualhead with NVidia card on Fedora 9
It`s simple to setting up DualHead in Fedora 9 . But may be some difficulties if you do it first time.
So, you connect two monitors to one NVidia-video card, power-on your computer and the 'X's already started.
Variant 1: setting DualHead by using X-settings tool.
The utility can be called "nVidia Display Settings" (if you use drivers from Livna ) or "NVIDIA X Server Settings" (for proprietary NVidia-drivers). The essence of both is the same, and it looks the same. They run from the menu "System" or from the console with command "/usr/bin/nvidia-settings" (you must be root)
Incidentally, if you prefer launched from the menu, very be advised to edit this menu (right click on "К" for KDE -> "Menu Editor") to run the utility from root. Otherwise, the utility will not allow you to save changes to Xorg.conf
After running utilities turn to its menu "X Server Display Configuration"and see that the graphic box shows2 rectangles, symbolizing the monitors. In fact, one of them is active. Click on second monitor, check the "Enable Xinerama" and exposes your preferences for the second monitor. Must have something like this:
"Display" tab
Model: [CRT-1 (CRT-1 on GPU-0)] ////// this is my second monitor - old CRT, you can identify a real model of the monitor
Configuration: [ Separate X screen ] ////// Options: "Disabled" - just disabled, "Separate X screen" - different displays/desktops, "TwinView" - duplication of the desktop to 2 monitors.
Resolution: [Auto] //////// or set what you need
"X Screen" tab
Screen Number: [ 1 ] /// "0" - first monitor, "1" - second one
Color Depth: [ 16.7 Million Colors (Depth 24) ] /// Well when we live to see Linux 32bit color?!
Position: [ Right Of ] /// - set position of the second monitor on the first; "Absolute" - absolute position, while the additional field indicates a relative shift in pixels.
MetaMode: [ 1 - ... ] /// did not touch unless you know the appointment or Set the desired value
After that all press "Save to X Configuration File" button. If you have an error something like "could not write to Xorg.conf" it means you are not root.
Now do Logout, enter new session and gives 2 monitors which are not duplicates but different desktops are with all delicious of DualHead`ing.

Variant 2: manual setting-up DualHead with some changes in /etc/X11/xorg.conf.
Here, I simply show my working file xorg.conf. Actually, you need to pay attention to section "Monitor", "Device", "Screen" (Please note - their 2 copies) & "ServerLayout", where we refer to section "Screen"
