20 years ago, I had a midrange laptop with a dGPU and while it played games with mediocre results, the laptop experience itself was also mediocre. Stupidly, 10 years ago, I bought a laptop with a dGPU again, but because NVidia didn't play nice with Linux back then, I don't think I've used that GPU for more than an hour or so.
Never again. A laptop with a dGPU runs counter to the things a laptop should be. Keeping gaming activities on a desktop is the best option in my experience.
A few months ago, I started working at an e-waste recycling company, and discovered that used Microsoft Surface tablets are what I've been looking for. My work "laptop" is a Surface Pro 5 with Debian (my work desktop is an Optiplex micro). I'm typing this on a Surface Go (with BlissOS) that I bought for myself. The cameras don't work on either and the work Surface never knows it's battery status, but I don't care (it lasts an entire afternoon with a barcode scanner, good enough for me).
I daily drive Ubuntu on this laptop. It has issues, but the Nvidia GPU is not one of them. Times have changed.
If you don't like a dGPU in a laptop, that's fine. But people have different needs. I travel a lot and do 3d content creation work.
