Yes DaVinci Resolve is supported on Linux. Unfortunately the free version of DaVinci Resolve does not include H.264/H.265/AAC support on Linux due to codec licensing issues though you can transcode it elsewhere first.
I think this will be the year of the Linux then.
Native photo editor with decent ux was the missing piece.
Even the paid version doesn't include aac support in Linux so you have to transcode the audio from videos recorded from your phone, with ffmpeg for example, prior to opening them with resolve. That's the biggest inconvenience it has for me in Linux. And plugins can't solve that either, because apparently can only add codecs for encoding, not for decoding.
