As others have suggested, QubesOS is a good one to have on your list. I’d probably use if it weren’t for its crippling effects on battery life.

Immutable distros are much friendlier to laptops and, as I understand, update in a way not unlike an Android device would. But I insist on some system-level customizations and I haven’t been motivated to learn how such customizations can be made to survive updates and the like.

I’ve also been eyeing NixOS, but with everything up and running on Debian smoothly for a few years, I haven’t found the excuse to switch yet. Along with customizing it to be a comfortable daily driver, I’ve also been trying to see how secure I can make my system as a fun exercise. While it’s not immutable, Debian is a good base considering the team behind it and how much is riding on its security, including internet-facing servers.

What I’ve done to harden Debian, if anyone’s interested:

• Apply Madaidan’s hardening guide judiciously. Roughly 2/3 of the measures made sense for my use case and it’s almost unnoticeable in my daily workflow.
• Have as few closed-source components as possible. In my case, intel-microcode is the only non-free package on my system.
• Install the hardening-runtime package, but remove its included slub_debug=FPZ kernel argument, which in recent kernels forces less secure unhashed pointers.
• XFCE is still not fully ported to Wayland, so I use slock, the X11 screen locker with fewest lines of code.
• Install the ufw firewall and default to deny
• Enable unattended-upgrades
• Everything including the /boot partition is encrypted. I have built coreboot with just the GRUB2 payload, which I configured to immediately bring up the LUKS password prompt. All other options are behind a password.

I also put together and maintain a ~16 GB clean system image of Debian set up exactly to my taste, which I clone to my machines as needed. This probably wouldn’t have been a thing if I knew about NixOS earlier, and it certainly hasn’t helped me switch over either.

Is the automatic scaling a recently-introduced feature to KDE? I have Plasma 5 on Debian 12, could that be the missing link, or is my configuration just wonky? Hoping to avoid editing every affected shortcut to include Gamescope.

Whatever comes with your distro or desktop environment ought to be enough for anybody.

Unless you have a minimal window manager that comes with only xterm. Then I’d install xfce4-terminal to get tabs and more reasonably sized text. If for some reason the distro or OS only has sh, I’ll also go ahead and install bash, but nothing fancier than that.

To be completely honest, I installed Jellyfin “bare-metal” and have been using it that way since after attempting to skim the Docker documentation and failing to understand how Docker works.

Awesome, adding to my current arsenal of alternative clients alongside FreeTube and NewPipe. One less chance for YouTube to force me onto their webpage.
