How to use the composite video jack of my laptop?

#1 Post by bugminer »

Hopefully I'm starting a thread in the right spot this time, lol! On my Toshiba Tecra 8000 laptop it has a composite video out rca socket. Today for something to do I decided to hook up a monitor to it and see if it was going. Nope! Not surprising though.

I looked in system information for clues to how to get working, I noticed when I clicked on "Display" that under "Extensions" it says "Composite". Does this mean there is some way to turn it on?

I don't desperately need the rca video out but I thought it could be fun.

could it be used as a second monitor in linux?

Thanks for any advice/help. I have puppy linux 5.2.5.

Composite video goes to something like a vcr or tv with a composite
input jack; much like svideo.

Works okay with Ubuntu, but haven't found a Puppy that will do
it right. Usually doesn't do color when it is partially working.

Could be the laptops I tried weren't up to the task. (Dells)

Inspiron 700m, Pent.M 1.6Ghz, 1Gb ram.
Msi Wind U100, N270 1.6>2.0Ghz, 1.5Gb ram.
Eeepc 8g 701, 900Mhz, 1Gb ram.

Hi rjbrewer, Yeah, I know what it is (ty though!).

I was just curious to know if it had to be turned on somewhere in puppy or if it was turned on by default.

Lobsters setups are the only ones I remember.

"xrandr -q" will probably tell you if its recognized and, if it is, let you turn it on.

:D Hello,
Enabling Composite under Display has to do with Composite Display via a compositing manager like xcompmgr, not an output choice...

I have to ask, when you say a Composite output, please describe it..
The little yellow RCA jack should be always on...
Generally, only S-Video needs to be switched...
$ xrandr --output S-video --set load_detection 1
$ xrandr --addmode S-video 800x600
$ xrandr --output S-video --mode 800x600

And set mode PAL or NTSC with:

$ xrandr --output S-video --set tv_standard ntsc
Close the Windows, and open your eyes, to a whole new world

Yeah, I mean the yellow RCA jack.

I want to use it and the main screen, not instead of the main screen.

Also, I know nothing about xrandr stuff.
