I think that most of usefulness of swap has passed now that we have systems with noodles of ram.

Please read this article authored by maintainer of Linux kernel memory management subsystem and cgroup subsystem, Chris Down.

And there is another article with some additional informations about swap authored by @farseerfc@sn.angry.im who tranlated the article above to Chinese.

I suppose displayport over thunderbolt plus embedded USB hubs in computer monitors gets close, but the display settings controllers usually require proprietary drivers and are vendor specific.

DisplayPort have DDC to control display settings. But I don’t know how much settings was standardized and implemented by vendor. But at least, the backlight was implement by most vendors, many users use it.

What ever DisplayPort do, HDMI do more badly. HDMI also requires Annual Fee to get document now (since 2021, before that the document was public available). And this is not the worst thing, the worst thing is the HDMI forum disallow anyone open source a driver which support HDMI 2.1 or higher.

It’s difficult to have. The members of HDMI Forum are almost the TV manufacturers and the members of VESA (the maintainer of DisplayPort) are PC and GPU munafacturers. So TV almost uses HDMI and monitor almost uses DisplayPort.
