If you're gonna reference the wiki, cite the right article[1].
Under the 'GPU Offloading' heading (the feature most folks want in dual discrete/integrated laptops):
> Note: This setting is no longer necessary when using the default intel/modesetting driver from the official repos, as they have DRI3 enabled by default and will therefore automatically make these assignments. Explicitly setting them again does no harm, though.
I had to do nothing out of the box to have a working PRIME setup on my work laptop over a year ago, and I'd never used a laptop with discrete graphics prior. My only driver issue was with DisplayLink (proprietary), where I had to pin xorg because it wasn't compatible with 1.19.
Most people want to use the proprietary drivers, because nouveau's performance is prohibitively low for gaming. And that only supports switching GPUs with a reboot.
It does work, but it's not very nice, which is what we are upset about.
eGPUs in a laptop format is a bit silly, you sacrifice the mobility of the laptop to get a very cut down discrete mobile GPU. AMD has started to eat this market alive due to the performance per watt advantage: https://redd.it/bc5hkg
Consumers are much more likely to bring a sub-5lb HP x360 everywhere than a bulky 8+lb laptop.
Your comment confuses me. Are you talking about external GPUs not making sense? Or dedicated GPUs in laptops?
Anyways, I'm pretty happy with the weight of my Dell XPS 15 which has an Nvidia card, but I regret buying it because of the lackluster Linux support.
I haven't seen any laptops with dedicated AMD cards at all lately, and until recently I had no idea that AMD's integrated cards were so competitive, so that's why I didn't. I plan to buy AMD next time I'm in the market.
