I've been struggling with nvidia on my laptop for quite some time, but I definitely wouldn't say it took debugging. There are clear limitations, primarily that on older chips the gpu never fully powers down when not offloading, but that was pretty clear from the start. And that's on Arch, using a port of a tool that was made for Ubuntu. On newer computers, it works even better. No matter what, there isn't much room for debugging, be that a good or bad thing.
