DaVinci Resolve is free-as-in-beer but not Free-as-in-Speech, and it's a pretty serious bit of software. In Linux, it lacks some of the codec support and "nice-to-haves" like automatically exporting to Youtube etc, but if you use Linux already you probably use ffmpeg already and you probably know what you're doing with it. You will need a fairly modern graphics card, but a low-end NVidia GT1030 will work perfectly well.
