Screen Casting – Linux

Screen Casting from Laptops Running Debian Linux to a Smart TV

If the Smart TV Supports Miracast

Using Miracast

1. Ensure Both Devices Are on the Same Network:

• Connect your Debian laptop and smart TV to the same Wi-Fi network.

1. Install guiscrcpy (GUI for scrcpy which supports Miracast for some devices):

   sudo apt-get install guiscrcpy

3. Launch guiscrcpy:

• Open the application and follow the instructions to connect to your TV.

If the TV Does Not Natively Support Miracast

Use a Casting Device

Using Google Chromecast

1. Install and Set Up Google Chrome:

• Ensure Google Chrome is installed on your Debian laptop.
• Connect the Chromecast to your TV and set it up via the Google Home app on a smartphone.

1. Cast from Chrome:

• Open Google Chrome on your Debian laptop.
• Click the three-dot menu in the upper-right corner.
• Select Cast.
• Choose your Chromecast device from the list.
• You can cast the current tab or your entire desktop.

Using VLC Media Player

1. Install VLC:

   sudo apt-get install vlc

2. Stream to Chromecast:

• Open VLC.
• Go to Playback > Renderer and select your Chromecast device.

Using DLNA (Digital Living Network Alliance)

1. Install minidlna:

   sudo apt-get install minidlna

2. Configure minidlna:

• Edit the configuration file at /etc/minidlna.conf.
• Set the media directories you want to share:
  sh media_dir=A,/path/to/your/media

2. Start minidlna:

   sudo systemctl start minidlna

4. Access Media on TV:

• Use the DLNA/UPnP feature on your TV to find and play media from your Debian laptop.

Use an HDMI Cable

1. Direct Connection:

• Connect your Debian laptop to the TV using an HDMI cable.
• Select the appropriate HDMI input on your TV.
• Your laptop screen should be mirrored to the TV.

1. Adjust Display Settings:

• On your Debian laptop, open the display settings to configure the display arrangement (mirroring or extending).

   xrandr --output HDMI1 --auto

Replace HDMI1 with the actual name of your HDMI output, which you can find by running xrandr without arguments.

Summary

• For Smart TVs with Miracast Support: Use guiscrcpy to connect.
• For TVs without Native Casting Support: Use devices like Google Chromecast, DLNA servers, or direct HDMI connections.

These methods will help you effectively screen cast from a Debian Linux laptop to a TV.
