HOW TO: Get component out on nVidia Cards.

HOW TO: Get component out on nVidia Cards.

This how to will explain how to get your nVidia card to output component to your HDTV, using the dongle provided by nVidia with you video cards.

FIRST BACKUP your xorg.conf file

Code:
cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup


Assumptions:
• You have nVidia drivers installed.
o If not see firewings HOW TO on doing this…http://www.fedoraforum.org/forum/showthread.php?t=99285
o Basically with the livna repo installed
Code:
su -c yum install kmod-nVidia
• The drivers are currently working on you VGA or DVI monitor
o Check this by
Code:
cat /etc/X11/xorg.conf | grep Driver
• should display “nVidia”, if says nv change it to nVidia
• su –c gedit /etc/X11/xorg.conf
• under device section change driver “nv” to driver “nVidia”
• Enable Composite out to the bottom of the xorg.conf file:

Code:
Section "Extensions"
   Option        "Composite" "Enable"
EndSection
• reload X (ctrl-alt-del) if all goes well continue.
For component out only:
Edit your xorg.conf file

Code:
Su –c gedit /etc/X11/xorg.conf
In the screen section change/add so it looks like this:

Code:
Section "Screen"
	Identifier "Screen1"
	Device     "Videocard1"
	Monitor    "Monitor1"
	DefaultDepth     24

	#------------480p----------------------------
	#Option	    "TVStandard" "HD480p"
	#Option	    "metamodes" "CRT: 720x480 +0+0"
	
	#------------720p----------------------------
	Option	    "metamodes" "CRT: 1280x720 +0+0"			
	Option	    "TVStandard" "HD720p"

	#------------1080i----------------------------
	#Option "TVStandard" "HD1080i"
	#Option "metamodes" "CRT: 1920x1080 +0+0"

	Option	    "UseEDID" "FALSE"
	Option	    "ConnectedMonitor" "TV"
	Option	    "TvOutFormat" "Component"
	Option	    "AddARGBGLXVisuals" "True"
	
                SubSection "Display"
                         Depth     24
	         Modes    "720x480" "1280x720" "1920x1018"
	EndSubSection
EndSection
Do not change the identifier, device, monitor, default depth sections.


Now we need to enable the resolution that you want. You may only have one resolution running at a time. Uncomment a section that you prefer. For example, on the example above 720p is enabled.

------------------------------------------------------------------------------------------------------

For Dual Monitors:
This is more tricky. Below I have a working dual xorg.conf file. You will need to edit it to match your setup. But it should be easy.

Code:
Section "ServerLayout"
	Identifier     "Layout0"
	Screen      0  "Screen0" 1280 0
	Screen      1  "Screen1" RightOf "Screen0"
	InputDevice    "Keyboard0" "CoreKeyboard"
	InputDevice    "Mouse0" "CorePointer"
EndSection

Section "Files"
	RgbPath      "/usr/X11R6/lib/X11/rgb"
	ModulePath   "/usr/lib/xorg/modules/extensions/nVidia"
	ModulePath   "/usr/lib/xorg/modules"
	FontPath     "unix/:7100"
EndSection

	Load  "type1"
	Load  "freetype"
	Load  "glx"
	Load  "dbe"
	Load  "extmod"
EndSection

	Option	    "Xinerama" "0"
EndSection

	Option	    "Emulate3Buttons" "no"
	Option	    "ZAxisMapping" "4 5"
EndSection

Section "InputDevice"

    # generated from data in "/etc/sysconfig/keyboard"
	Identifier  "Keyboard0"
	Driver      "kbd"
	Option	    "XkbLayout" "us"
	Option	    "XkbModel" "pc105"

		Modes    "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
	EndSubSection
EndSection

Section "Screen"

	Identifier "Screen1"
	Device     "Videocard1"
	Monitor    "Monitor1"
	DefaultDepth     24

	#------------480p----------------------------

	#------------720p----------------------------
	Option	    "metamodes" "CRT: 1280x720 +0+0"			
	Option	    "TVStandard" "HD720p"

	#------------1080i----------------------------
	#Option "TVStandard" "HD1080i"
	#Option "metamodes" "CRT: 1920x1080 +0+0"

	Option	    "UseEDID" "FALSE"
	Option	    "ConnectedMonitor" "TV"
	Option	    "TvOutFormat" "Component"
	
	Option	    "AddARGBGLXVisuals" "True"
	
SubSection "Display"
		Depth     24
		Modes    "720x480" "1280x720" "1920x1018"
	EndSubSection
EndSection

Section "Extensions"
	Option	    "Composite" "Enable"
EndSection
FYI: With dual monitors I have been unable to get AIGLX or Desktop-effect working.

Hope this helps. This is my first HOW TO article. Please post corrects/additions. This took me forever to get working. Hopefully this will make it easier for people in the future.
