well being a crazy alpha tester obssesed with changing every setting imaginable i've been working with Xorg to get my TV to work as a second monitor like under windows and amusingly enough it will do it .... just not while running gnome .... gnome is one of the most ass munching resource hogging window managers i know of but lucky me i'm on the AlagorOS and have JWM installed by preferance so after frying GDM and restoring WDM as my display manager i've managed to get into JWM in a very roundabout manner and then i've reconfigured JWM so that my startbar is only existant on one of my desktops not both because to start a program on the second monitor i'd only have to right click the background anyway so now i've got my system kinda sorta the way i want it but oddly enough the combination seems to be in a 1600 by 600 resolution which sucks ass because it should be something like 2048 by 768 but i'll work that out here shortly
it seems that all of this was one of those hidden ubuntu configs because when i looked it up i found out that SVIDEO output wasn't supposed to be entirely supported so it shipped with settings that simply ignored SVIDEO ports on your video card so what i had to do was set it so that it saw two monitors and positioned them side to side and then add a virtual display and oddly enough it works under JWM and possibly blackbox and any non "Standard " window manager ( gnome KDE XFCE ect.) but if you simply turn on the setting so that the system can see the SVIDEO port it doesn't want to do anything more than clone the screens in gnome ( in other words you see two screens display the same thing in very differant resolutions in a very ****ty manner ) but under jwm this works fine however alagor OS will not be able to ship with support for dual monitors like this because of differances in video cards and everything so while it will have the ability to do it don't expect to find an option to setup multiple displays because the way i did it may not necisaraly be the way you will do it however if your willing to spend the time to set it up i will send you my xorg.conf and tell you what you might need/like to change to get it working
anyway theres still some odd things i've got to iron out but for now it looks like its just a few miss configs
