That's looks much better.
I tried the older version for my htpc and didn't like it.
I would love to see this keep improving.
Is this basically a DE? Could you run steam and full on gaming PC off this?
Baeically its a somewhat stripped down version of plasma ment to be used with a controller or remote, but it is only a DE, so applications that arent controller friendly are going to stay that way.
Setting steam to launch big picture by default tho would basically turn any powerful pc you have into a steam console (steam big picture) with an extra home screen (plasma bigscreen) that shows all your other applications
It's an alternative shell for Plasma, so theoretically you should be able to do anything in it that you can do in Plasma.
On my Arch box it installed a minimal set of Plasma utilities to support it, which means my setup is still very limited (and I can't turn off screen lock!), but I haven't tried if it would change if offered a full Plasma install.
I can most certainly launch Steam, Kodi, Jellyfin etc.
What does DE mean in this context?
It's a Linux concept. Basically, imagine you could have a Windows 11 PC with the Windows XP GUI or with the macOS GUI. In Linux, these kinds of different GUIs are just desktop environments, which you can install as you see fit.
Conversely, you can also have an OS without a desktop environment, which is basically what's used on Linux server PCs.
Desktop environment
Or is it a "mode" of KDE? Like can you use a distro of KDE and then put it into Bigscreen mode?
It's using plasma-nano session, which is a minimal Plasma session, and adding a launcher and settings app from what I can see.
You can run it in a regular window if you install the dependencies and use kde-builder to compile it and run. See the Dev docs at https://invent.kde.org/plasma/plasma-bigscreen/
If you do decide to install all the kde-builder stuff, I'd suggest you use a distrobox container to make it easy to remove the many, many packages that it will install in order to set up the build environment
Is just another DE which you can choose when logging in
ok, but it would be wonderful if you could have this run on the TV, while the main screen runs normal plasma.
speaking of that, it's probably doable with setting up multiseat, probably in systemd logind
Yeah, wanted to suggest multi seat, but never played with it myself, so no clue how both sessions interact
