I actually thought about that, too. I looked at KDEconnect. But in the end, I wanted to add some gaming capabilities if I added a PC to the TV. But it's great to hear that it works well :)

I'll try to do a writeup.

No containers (I actually have zero experience with containers). But if you know how to use them, it should be possible.

I'm using autologin and sleep mostly. I don't have to enter my password at any time (except when doing root stuff to install programs but not in everyday use). On boot, I do have to enter my disk encryption password.

You can autologin through some options in systemctl, but if you use standard DEs such as Gnome or KDE, there should be an option in the settings.

It was called moss dragon and I saved it maybe 10 years ago. Unfortunately, I don't know the author or the website anymore. I hope it's ok to still share.

I tried some of that too. But for most desktop environments, the gamepad wouldn't work.

But great that it works for you. Nice thing about Linux :)

It's just on the DP-out of the PC. I tried it on two different PCs and it worked. From my understanding, it should be supported if the PC has DIsplayport 1.3 or newer. But maybe I was just lucky.

I then had to play around a bit with cec-ctl (with the help of the Arch and Ubuntu manual pages https://man.archlinux.org/man/cec-ctl.1.en https://manpages.ubuntu.com/manpages/focal/man1/cec-ctl.1.html ). I think I also tried a bit with --cec-version-1.4, but I don't remember the details (I only saved the scripts that were working).

Sorry if I can't be of more help.

It's simply connected by bluetooth or by dongle and Debian managed to do everything. Flex-launcher also supports it by default. I added some more key-combinations using input remapper such as closing programs, returning to launcher, changing volume.

I actually had some problems with input remapper on Debian and had to install the latest release (the one from the repository didn't work).

I'm powering on/off the TV through CEC, see my reply above: https://programming.dev/post/50315130/23805655

I'm using a Displayport to HDMI-adapter and then a regular HDMI-cable (so the PC needs a DP-output). There are also some other options, but this was the easiest for me. I got most info from the Arch wiki https://wiki.archlinux.org/title/HDMI-CEC.

It also doesn't work for all DP-HDMI-adapters, they need to be modern enough/support the protocol. From what I remember about finding the specific one I got, I think ones that support 8k should be good enough. I got one from Ugreen.

Yeah, I've been looking/waiting for quite some time. hoping that a good solution would come along. I also tried Steam (big picture mode). But that still contains ads (for games) and is not that customizable. In the end, I'm really happy with flex-launcher.

I've switched away from most streaming services. For one month, I watched Netflix in the browser. It's a lower resolution, but works ok. Mostly, I download stuff, which is publically available or use public broadcasts like Arte.
