I used to run Steam BPM under steamcompmgr, and had Kodi as a shortcut via “add a non steam game”. You could do a browser similiar way. steamcomomgr is a X window manager that handles scaling for those small dialogs for TV screen. Gamescope is similiar for Wayland.

Now I have Debian stable running plasma-bigpicture, which is a KDE set up for TV screen. Flatpak gives the latest Kodi and other apps that the OS doesn’t keep up to latest version, and I do enjoy the stability of the underlaying OS for HTPC use.

Which is better? It depends. If you do mostly games and Kodi, and use a game controller for controll, then Steam BPM. It has a controller friendly OSD keyboard for text, and the upscaling of starting dialogs especially for older games if a nice feature. For youtube, this may not be the best option, and it needs a bit more work to set this up for the Display manager as a xsession.

Plasma-bigpicture is nice if you want to run apps made for traditional desktop, and have a keyboard and mouse. Say for youtube you may want to use some unofficial players to get rid of ads. You can set Steam to auto-start on the background to get game controller input working on the desktop. Setting this up is as easy as installing one package, and switching the session via login manager.

Ofcourse, you can have both and switch from you login screen. You can’t have Steam running on the login screen for that game controller friendly keyboard for login, but you can set automatic login for the one you use most, and switch by logging out.

As for distro, pick the one you like most and know your way around.

I hope this helps, have fun.

There is also Kaldi, but it’s not on F-Droid though.

Have you tried the fixes in the comments of this page?

https://aur.archlinux.org/packages/gzdoom

I find the comments in the AUR package page the best source of information to debug AUR issues.

Anyway, if you don’t want to use exactly that AUR package, there are multiple ways to install gzdoom witch some may be easier to install. You many different packages come up when you search gzdoom.

And what comes to other options, for Steam users there is luxtorpeda that integrates with Steam. Lutris users have their gzdoom runner. For the rest there is flatpak version available.
