S-Video hook up to TV

I just got a desktop computer from a friend with Linux on it and I'm completely unfamiliar with the system, but I haven't gotten a chance to try it yet because I was planning to have my monitor be my television screen. My television, however, only has three plug ins: DVI, AV, and S-Video. The computer came with an extra video chip that has an S-Video output on it. So, I tried plugging the S-video from the computer to the TV. I turned it on. While in DOS, the screen was fine. But, as soon as the Linux system started up, the screen started flashing up and down. Like this, it is completely impossible to work on it. I need to know if there is a Linux setting to adjust the video output so that this doesn't happen. I can borrow a monitor to set it up correctly, but I need to know how.

    Can you tell us what type of linux OS you have? The name is displayed across your monitor when your system boots up. This will help us find a solution.

    or you can post a picture of the desktop from the screen when it is running and we can point you to available tools.
  • Yes. It's Ubuntu.

    You can go to System -> Preferences -> Display to see if the s-video connection is being detected and setup the screens as you wish.

    You didn't mention about your graphic card but probably if you want to display something on your LCD TV you'd better stay with DVI, VGA/HDMI/DVI output settings are "enabled by default" on most linux distro (even Ubuntu), SVideo output is generally disabled if you don't configure something from your XOrg video setup config

    etc/X11/xorg.conf - if it is using 'vesa' try 'i810' (for Intel graphics). You might also need to put the proper values for HorizSync https://xender.pro/ https://discord.software/ https://omegle.onl/
