Extended Desktop onto TV
 
I have Ubuntu 6.06 with an ATI 9000(w/ s-video out). I want to know how I can setup an extended desktop onto a tv using the s-video out(just like I do on XP).

The setup depends on whether you want your TV to be an extension of your current CRT display, or a seperate display.

Here's the relevent xorg.conf settings I use for a SEPERATE DISPLAY with a nVidia card, svideo hooked up to a TV running at 640x480, VGA hooked up to a CRT running at 1024x768. It is very important to get your HorizSync and VertRefresh setup correctly for your TV. Check your TV's specs. Setting these too high can damage or destroy your TV. HorizSync of 30-50 is generally considered safe for TV's I believe, 60 for VertRefresh. But no guarrantees on these settings from me - verify your TV's specs yourself!!!
