Oh yeah I gave up trying to run LConnect on linux a while ago. I then looked into alternative tools people have made, of which there are a few and they seem great, but none of which (when I looked last) support my specific fan models. So my current solution is Windows 11 in a barebones VM that autostarts. It literally just runs Lconnect and nothing else, and the only things passed through to it are the USB controls for the fans. It has allowed me to at least control the colours, and screens, though not fan profiles or stats.
