How can I connect my Ubuntu 20.04 system to a wireless display?

I’m in a bit of a pickle trying to connect my Ubuntu 20.04 system to a wireless display, and I could really use some help. I recently got this awesome smart TV, and I’m super excited to use it as a second screen for my laptop. I can already tell it’ll make working on projects and binge-watching shows a lot more enjoyable. But every time I dive into the settings to figure out wireless display options, it feels like I hit a wall.

I’ve done some basic research, and it seems like there are some tools and protocols out there designed for screen mirroring. I’ve heard about technologies like Miracast and maybe using something called GNOME’s built-in features, but I can’t figure out how to actually make the connection happen. To be honest, the whole process seems overwhelming, and I don’t want to mess anything up or get stuck in some weird configuration.

I tried looking into the “Displays” section in the settings, but all I see is my laptop screen and no options for a wireless display. I’ve also tinkered with the command line a little but didn’t find anything that felt user-friendly. I keep thinking there must be an easier way to do this! Can anyone guide me through the actual steps to connect my Ubuntu 20.04 to the wireless display? Or at least tell me what I might be doing wrong?

Also, if there are any specific drivers or applications I need to install first, I’d love to know about those too. I just want to get my laptop and TV to talk to each other without too much hassle. I know tech can be finicky at times, so any insights or tips from those who have done this successfully would be hugely appreciated! Thanks a ton!

      How to Connect Your Ubuntu 20.04 to a Wireless Display

      So, you’re trying to connect your laptop to that shiny new smart TV, huh? I totally get where you’re coming from—tech stuff can be super confusing sometimes! But don’t worry, I’m here to help you out with some steps that might just do the trick.

      Check If Your TV Supports Miracast

      First off, let’s make sure your TV supports Miracast. Most smart TVs do, but it’s good to check the settings on your TV to see if there’s an option for “Screen Mirroring” or “Miracast.” You’ll want to get that ready first.

      Install Required Packages

      Next, you might need to install a package called gnome-network-displays. Here’s how you can do that:

      sudo apt update
sudo apt install gnome-network-displays

      Launch the Application

      After that, just search for Network Displays in your applications, or run it from the terminal by typing:

      gnome-network-displays

      This should launch a little window that scans for available wireless displays. Just keep it open!

      Connect to Your TV

      Now go to your TV and enable the screen mirroring feature (you might have to find it in the settings). Once your TV is ready, it should show up in the Network Displays app on your laptop.

      Click on your TV in the app, and see if it connects. You might need to accept a prompt on your TV for the connection.

      Troubleshooting

      If it still doesn’t show up, here are a few things to check:

      • Make sure both your laptop and TV are on the same Wi-Fi network.
      • Look for any software updates for your Ubuntu system.
      • Try restarting both your laptop and smart TV.

      Wrap-Up

      Hopefully, these steps help you get your laptop talking to your TV! If it’s not working, don’t hesitate to reach out to forums or ask your tech-savvy friends. You got this!



    2. To connect your Ubuntu 20.04 system to a wireless display, you need to ensure your TV supports the necessary technologies, such as Miracast. First, make sure your TV is on the same Wi-Fi network as your laptop. While Ubuntu’s GNOME interface has built-in support for wireless displays, sometimes the functionality may not be enabled by default. To check for this, you can try installing a package called gstreamer1.0-plugins-bad which may enhance multimedia capabilities on your system. Use the terminal to install it by running the command sudo apt install gstreamer1.0-plugins-bad. Once installed, navigate to the ‘Settings’ > ‘Devices’ > ‘Displays’. Here, you should see an option to connect to a wireless display if it is detected. If not, restarting the GNOME Shell with Alt + F2 and typing r may help refresh the connection.

      If you still do not see your TV listed, consider using a tool called gImageReader to ensure you have the necessary drivers and protocols enabled on your system. To install it, run sudo apt install gimagemagick in the terminal. After doing this, head to the ‘Settings’ again and check in the ‘Displays’ section. Another alternative you could explore is using the screenkey package, which can mirror your displays over the network. To install it, run sudo apt install screenkey. Once everything is set up, you can restart your system to ensure all changes take effect. These steps should help facilitate a smooth connection between your laptop and your smart TV for an enhanced viewing experience.
