Brief: KDE’s upcoming Plasma Bigscreen project lets you use open source technologies to turn your regular TV into a smart one.
Smart TVs are the new normal these days. Mostly based on Android, these smart TVs let you play YouTube, Netflix, Spotify and other streaming services. You can even use voice commands to control your smart TV.
One major problem with these so-called smart TVs are that they probably are spying on you. Your data is being collected with or without your knowledge.
This is the problem KDE’s Plasma Bigscreen project is aiming to solve.
Plasma Bigscreen: Make your TV smart with open source technologies

You probably already know about the KDE project. It started as a Linux desktop environment project more than 20 years ago. The KDE project grew bigger and this is why they created Plasma desktop environment to make it clear that KDE is no more just “K Desktop Environment”.
The Plasma project itself is quite versatile. You can of course use it on your desktop Linux computer. Plasma also has a mobile version that you can run on Linux-based smartphones like Librem5 and PinePhone.
The Plasma Bigscreen is a new project from KDE that aims to provide interface and features similar to what Smart TVs provide.
All you need is a single board computer like Raspberry Pi and a TV with HDMI port. Install Plasma Bigscreen on your device and connect it to your TV.
Plasma Bigscreen features: More than just a media server

Though it may look like one at the first glance, but Plasma Bigscreen is not like Kodi and other media servers for Linux. It’s more than that.
Control with your regular remote
You don’t need a new specialized remote control. Thanks to CEC, you can use your regular TV remote control.
Voice control with open source Mycroft AI
Plasma Bigscreen takes advantage of the open source Mycroft AI project. With Mycroft built in to Bigscreen, you can use voice command to play content, check weather and control other aspects of your smart TV. You can further train this AI by teaching it new skills.
Traditional desktop applications
Plasma Bigscreen delivers not only media-rich applications, but also traditional desktop applications redesigned to fit the Bigscreen experience.
Free and open source software
The most important feature is that it is an open source project and it uses other open source technologies to give you the complete control over your data and your smart TV.
Since it is open source, I believe once it is released, there will be a few vendors providing it as a plug and play device.
How to get Plasma Bigscreen?
Plasma Bigscreen is still in beta phase and there is no definite timeline for the stable release.
However, the beta version is also working good on devices like Raspberry Pi 4. Here’s a video by one of the developers working on this project.
If you have a Raspberry Pi 4, you can download Plasma Bigscreen beta version from its official download page and follow the steps here to install it.
Personally, I am really excited about it. I am going to take out some time and try it on my Raspberry Pi 4. What about you? Do you think the project has potential? Will you give it a try?
Hello, I’m intrigued by how this works. Is there a way to access the local terminal and do AP + Wifi hotspot? Thank you.
I think that should be possible via SSH or some other remote desktop access tool.
Hello, I’m having trouble booting it on my pi 4B 8GB RAM. It’s stuck on “[OK] Started Update UTMP about System Runlevel Changes.” I’m constantly reflashing it and no luck. What should I do? Thank you!
How can i develop and add my own app?
Some misinformation being spread here.
Plasma Big screen is an alternative plasma shell, it is built on KDE Frameworks 5 and so is architecture agnostic. x86 or ARM doesn’t matter. It’s not a new OS, you could conceivably install Kubuntu onto an x86 mini PC then follow the build instructions to install the 10 foot UI. After that change your auto log-in settings.

Thank you for this. Even the official KDE Plasma Bigscreen site makes it sound like it’s exclusively built into an OS image for Raspberry Pi 4. https://plasma-bigscreen.org/
It would be great if they would include instructions for x86 computers right on that page for those of us that have an HTPC instead of a Raspberry Pi.
Tried it on our semi-smart Panasonic TV with it installed on a new Pi 4b, where it worked so-so. I feel it still has a long way to go before becoming a serious home theatre contender. GUI lacking setup choices for finer control. It feels not to be very rubust. But eh, it is a beta release. I’m watching with interest.
