How do I get my tv to be the display screen for my laptop? I plugged in the S-Video cable to my laptop & tv…then I entered <xrandr> , and it says TV connected. If it is connected…how come I don’t see it on tv? I also did <xrandr --output TV --auto>.
did you change it on your tv also? what I have to do is select input on my tv or tv remote and change that and it should work.
If that doesn’t work then depending on your type card you might have to make adjustments in there. I don’t have a laptop so I am not familiar how it works for you, but I have an ati card and I had to go to the ATI control center to make the changes I wanted .
Of course I made sure it was set to the correct video input on my tv. Below is from my xorg.conf. Thanks

No help getting this to work? I just tried the EXACT same laptop with windows installed on it, and when I plugged in the s-video cable from my laptop to the TV, within 30 seconds the TV became my display along with the laptop screen. Telling me it can’t be done on Linux? Hard to believe that no one knows how to do it. Should be fairly simple.
‘Connected’ just means PHYSICALLY connected. So, when I do just ‘xrandr’,
I see whether the s-video cable is plugged in. But, you have to do the
‘xrandr --output TV --auto’ to get it to actually bring up the image on the TV.
And, when you then do ‘xrandr --output TV --off’, it shuts off the image to the TV.
I have the lesser ‘945 GM’ Intel hardware. [Note: ‘xrandr’ is implemented for
all Intel graphic-drivers, but only for very FEW nvidia and ATI hardware/drivers.]
Clearly, it’s implemented and being triggered for your card, in that you see the 3 outputs.
My questions for you are: Which ‘DE’ (e.g. Gnome, KDE3, KDE4.04, KDE4.1,etc)
are you running when you try? (It works for me, in both KDE3 and KDE4.1,
but initially in KDE4.1, it didn’t…instead I got some msg about not finding ‘crtc’, but
that went away after responding to some special KDE4.1 configurer that popped up
and then rebooting.)
Do you get any (error) msg when you do ‘xrandr --output TV --auto’ or does it
just come back to a prompt?
