From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Why I need extra kernel modules to be able to run Wayland on nvidia? (sh.itjust.works)

If i run X.org i dont need to modify my kernel or its configs, it just works well (well, well for X.org) out of box. With wayland its the other story. I need to enable nvidia-dkms module and much other stuff to should be configured. There is a whole page about enabling hyprland on nvidia.

https://wiki.hyprland.org/Nvidia/

I ran into troubles trying to set up wayland preperly with nvidia, it has many issues and visual artifacts. I know that the problem somewhere in my kernel set up, but i feels like there would be no problem if hyprland/wayland would not require that granual configuration.

I keep thinking about wayland as a fullscreen videogame that just draws windows (in wayland it called somewhat else though, dont remember the term). And this is kinda weird for me that a video game needs special kernel modules.

Probabely if in wayland they could not require this extra set ups on nvidia, they would do that. They should have some reasons for not doing that i just want to know why?

Thank you :3

That's the Nvidia drivers. Dkms just builds to match your kernel when the kernel updates. Intel and AMD contribute driver code so you don't have to do anything extra but Nvidia doesn't do that because they are shits.

As far as not needing it for x11 you are either using nouveau, the reverse engineered drivers which last I tried are effectively useless for any modern workload, or a non dkms version of Nvidia driver provided by distro maintainers or someone else and just didn't notice.

Nouveau got way better I heard

Probably nvk which I think just completed vulkan feature set for the newest cards recently, but is not reaching the windows fps yet. I still haven't gotten over Nvidia betraying me by dropping the GTX 460 from drivers at a time when it was still more than enough for me so I don't follow it very carefully.
