I spend some time trying to figure it out. Many different configurations of xorg was used and i never got to the point when xrandr shows two screens. There is always one. According to manual:

1 - Integrated TV Encoder
2 - sDVO B port/RGBA port
3 - sDVO C port
4 - Internal LVDS port
5 - Analog port

Luca, what should be the number of my D-SUB? If i knew it for 100% i could further investigate this. And now i have to check every change plenty of times.

PS. Just got to create this post. Didn't have time yesterday to do this. Thanks.

Ok, i attach the xorg.conf with tvout working. It is harsh, if you want tv-out you need to connect d-sub and restart the xserver with ctrl+alt+backspace.

1. It is configured to clone, becouse if your tv-out is outof sync you dont left without any monitor=only restart would save you
2. Becouse of cloned you can only get same resolution on both monitors.

It can surely be tweaked even more, and ill try to do it.

Note: i have Benq U121 so it is possible it can not work on yours but it is suppose to work.

Added some lines that change resolution to 1280x1024 if second monitor is connected. If not it simply display 1366x768.

I try to active xinerama and to have two dual independient screens. I attachment my result.

It's works, but it have some problems. you can have two independient desktop, without any conexion beetween them (its dificult to me explain it).

xinerama option work, but you get a problem with resolution of the monitors (you get a mistaken resolution):
 Xlib: extension "RANDR" missing on display ":0.0".

I'm sorry for my english, and i hope It will be helpful

This my xorg.conf. It is for the fitpc2 which has no lvds, only a HDMI port carrying DVI (no sound).

I connect this to my TV through the HDMI connector marked DVI. This seems to be working well for my fitpc2 (v1.4 1.6GHz 1GB ram, 8GB SDD).

I downloaded the driver manual from the intel site:
