They look great, thanks for the suggestion.

Is there a way to assess which packages on my linux distribution aren't open source? I'm planning on having a secondary machine which is exclusively open source, but not sure how I would go about ensuring that is the case.

Great! This is the kind of answer I've been looking for. Thank you.

No biometrics! Just wanted to clarify the only difficulties related to typing my password are its length

Agreed - the message I was trying to convey is that I use a very secure password, which sacrifices convenience for security - is this necessary though? I have no concerns related to memorising or particular difficulties typing it out as it follows a passphrase structure for the most part.

I'll give it a shot and see if it's compatible. Cheers

Not too familiar with it, in what way would you consider it better?

I'll have to give it a try! Hopefully not too many dependencies :)

My use case is a pdf of a book which is meant to be read across two pages - wouldn't work if it's displaying pages 1 and 2 together instead of pages 2 and 3, if you see what I'm saying. Does Zathura allow for that?

I'm on XFCE, so was hoping for an alternative to Okular!

Thanks for pointing this out.

Arch wiki is superb, couldn't have installed or configured Arch without it.

Both :) Manual classic install doesn't strike me as particularly complicated.

Just checked, I'm using the deb package.

Would you consider all activists on the same threat level? I was imagining what the Just Stop Oil protesters in the UK might consider their threat model, I'd imagine it would be different to an activist in Iran or Russia for instance. Am I wrong?
