Not a native speaker, so I could be wrong about this:
I’ve seen a construction using proper nouns (eg. Annas Haus) where an “s” indicates possession, but no apostrophe. This doesn’t seem to apply to non-proper nouns (das Haus der Frau) and is different from normal genitive construction that adds an “s” to masc/neut noun genders (das Haus des Mannes)
I was using Manjaro KDE and ended up switching to Pop OS because Manjaro would never work right with my GPU. Pop OS has worked very well out of the box though.
