    There doesn’t exist much hardware that has fully open firmware enitely on mass market. I’m not talking about GPUs and CPUs but even WiFi dongles . The FSF is pretty hypocritical in that they’re okay with closed firmware which is built into devices themselves, but they’re not okay with firmware that comes as a file. This is nonsense. Also, they forbid distros which give you the ability to install non-free software even if you require it for your work, forbidding even Electron and fonts which have non-free licenses. This is not possible to live with in the modern patent world. And btw blobs not exist anymore in linux code of torvalds repo it was sepearated long time ago

    But did u install cuda package davinci not working without it ,to have less pain just install nvidia-dkms package,and about dynamic switching exist tool like switecherootctl ,but davinxi smart enough already it can detect multi GPU setup and gonna use card which it like more,so in ur case it gonna use nvidia.I just guess u don’t have installed cuda,and there zero literally magic actually ,u just need two package from nvidia which I already mentioned
