What's the use case? Is there a reason that the disk is not unlocked at boot/login?

I think any distro will do really. I'd go for something that is friendly to new users, if you're not very familiar with Linux in general. For example: Linux Mint. Here is an example on how you can get your installation setup easily: https://www.youtube.com/watch?v=IyT4wfz5ZMg

Regarding your Valve Index. It will likely work, but don't expect it to be very easy to get it running well. I'm currently on Arch Linux with red team hardware and a Valve Index. For example, you will need to ensure the udev rules are set properly: https://github.com/ValveSoftware/steam-devices. New issues occasionally arise, see: https://github.com/ValveSoftware/SteamVR-for-Linux/issues. Currently, it's not switching audio devices automatically, so I use pavucontrol (with PipeWire) to switch that manually.

Love it. Too bad it's missing the eating sound we all know so well

Personally, I never do it. I like to invest quite a bit into a world. The idea of having that being taken away because I do something silly feels awful.

To each their own of course. I can imagine it gives it that more of a thrill.

Could be a good idea for you to determine why you would want a hardcore world and what you'd feel if that ends.

Oh I didn't know that yet! Amazing stuff.

You're in luck. As far as i recall wincompose is inspired by Xorg's Compose feature (https://github.com/samhocevar/wincompose?tab=readme-ov-file#features). Depending on your installation you can toggle it via some settings, or by running: setxkbmap -option compose:ralt

I always find the book useful for this stuff: https://wiki.archlinux.org/title/Xorg/Keyboard_configuration#Configuring_compose_key
