I was a manjaro i3 user for months on my old laptop, but got a new one with an optimus setup (nvidia card with intel igpu). Yeah, I know, "nvidia bad for oss etc.", but that's what was sold. And cuda is still the gold standard for compute. I had to switch because I couldn't get gpu switching working on my manjaro; nvidia card was stuck in D3 state. Very sad, though I'm now on i3 arch and happy.
