Question Nvidia TV-out problems on Fedora 4


G'day

I am using FC4 and a GeForce 6600GT and have been trying to configure dual head output using the display settings so i can have my CRT monitor and my TV ( via S-Video ) hooked up to the same video card. I had already runed my last installation by configureing my xorg.conf file and instaling drivers left-right and center and things became so bad that i had to do a re-installation today ( couldnt even get 3d acceleration working ). Does anyone know how to configure X to do this using one video-card ? i know it is possible to do on XP and am dissapointed to see there is no GUI app to do this here but right now i will do anything to get it working.

Thanks.

Add the following (or something similar) to your device section. Make sure you have driver specified as nvidia and not nv.

Code:
Option      "TwinView" "yes"
Option      "MetaModes" "1024x768,1024x768;800x600,800x600"
Option      "TVStandard" "NTCS-M" #or PAL-B etc.
Option      "TVOutFormat" "SVIDEO"   #or COMPOSITE
Option    "ConnectedMonitor" "CRT, TV"
Example config

well, i tried the config you mentioned and it worked however, my CRT monitors rez was messed up ( i was not able to change it from 800x600 to 1280x1024 which i use ) and on top of that the desktop was spanning between the 2 screens. so i turned of twinview and manually added higher rez's for my CRT monitor. next restart, everything goes perfect and my screen rez is 1024x768 ( bearable ) and the TV is showing an exact clone of my desktop ( exactly as i wanted ) but i get a rude shock when i try running doom3 which doesnt load. apparantly, the xorg loaded the standard vesa drivers and not the nvidia ones ( no 3d acceleration ). i manually changed the drivers to "nvidia" in the xorg.conf file and upon restart the comp loaded fine with 3d acceleration but the tv-out is no longer working.

is there anny way to get the tv-out working without having to manually configure the xorg file everything and rebooti ??

The Metamodes have to relate to the Modes in the screen section or else it will not work. Below is my Metamodes and Modes lines.

Code:
Section "Device"
..
Option "MetaModes" "1400x1050, NULL; 1400x1050i, NULL; 1400x640, NULL; 1280x1024, NULL; 1280x1024i, NULL; 1280x960, NULL; 1152x864, NULL; 1024x768, NULL; 800x600, 800x600; 640x480, 640x480"
..
End Section

Section "Screen"
..
Modes "1400x1050" "1400x1050i" "1400x640" "1280x1024" "1280x1024i" "1024x768" "800x600" "640x480"
..
End Section
As you can see I used NULL to make sure TV out will not work at the resolutions that are not supported by the TV out hardware. However nVidia has put a limit in software that TV out can not output 1024x768 even though the hardware can do this.

If you want TV out in games make sure you specify the resolution that outputs TV out. Also make sure saturation is set at about half by using nvidia-settings in order to get color.

BTW, I used Clone for TwinViewOrientation.
