Nvidia: Partial rewrite to bring up to date with new developments

[fxzzi]

Hello again, this is the second time I've done this lol

I was getting a little tired of having people in the Discord keep complaining about electron flickering, when it has been pretty much solved for a while now, so it pushed me to just rewrite most of the Nvidia page on the Wiki to hopefully mitigate some of that.

There are a few opinionated changes I've made here. I felt they were what was best for the page, as they either contained information which were for Nvidia drivers so old they shouldn't even be using Wayland, or they were unneeded in my eyes (i.e. fixing flickering with those weird power management options)

I'm still unsure as to whether I should keep some of this "legacy" info here. i.e., containing info about how to enable modeset and fbdev, when they've also been enabled by default for a few months. Let me know what y'all think and whether or not we should keep this info.

Any criticism is welcome, I want this page to be as easy to read as possible since we have a lot of Nvidia users (including me) and most of the issues being reported are just the same thing over and over again at this point.

CC @fufexan since fuf reviewed my last PR about this (#601)

Generally looks good, but I have a few questions:

1. Does suspend work now on nvidia-open-dkms?
2. Does hardware.nvidia.powerManagement.enable handle the kernelParam as well now?
3. Is the NVreg_RegistryDwords fix no longer needed?
4. __GLX_VENDOR_LIBRARY_NAME?

Additionally, mentions of Hyprland/Wayland/Xwayland or some other project should be capitalized.

1. Suspend is now working for me as of the latest 570xx releases with open kernel modules. I'm not sure if its still a hit or miss tbh, I can add that section back if you'd like.
2. Yes, it does, and I think it did for a while actually: https://github.com/NixOS/nixpkgs/blob/0196e5372b8b7a282cb3bbe5cbf446617141ce38/nixos/modules/hardware/video/nvidia.nix#L659
3. This is one of the opinionated changes that I was mentioning. This section was added a pretty long time ago and I don't think it holds true anymore considering the developments we've had in explicit sync and syncobj in electron, cef, and hyprland itself. (I also don't think its a very good workaround anyway xd, it messes with power management stuff and forces your gpu into a high power state for no good reason, I also haven't seen anybody in practice actually using this workaround on the discord)
4. It was originally suggested to try removing it on the wiki because of some bugs years ago, but these have since been fixed. I haven't seen any reports in years of people having issues with it set.

For your last point, sure, I will have a look.

Okay then, lmk when this is ready.

[fxzzi]

okie dokie, I've made some changes. Let me know if anything is still missing.

[fufexan]

I think it's alright. @gulafaran you have Nvidia iirc, do you mind checking this as well?

[matjam]

Good refactor, I think its overall an improvement.

Left some suggestions.

I re-added the nuclear method, but upon conversation with @gulafaran i decided to remove it again as originally intended.

It's not a very good workaround tbh, stuff should be fixed in Hyprland, Electron, and Chromium now. (thanks tom, ikalco, plasmapower, and others)

Most of those options are either removed or not really working either since a long time ago , https://forums.developer.nvidia.com/t/kernel-module-option-nvreg-registrydwords-for-powermizerenable-doesnt-work-on-530-41-03/247610

Still waiting on Vaxry's response, but should be ready to squash and merge once that's done :)

[vaxerski]

oops didnt notice the ping

[fxzzi]

@fufexan should be ready for any final reviews now.

edit: also squashed

[fufexan]

Kinda long review but I felt like a lot of stuff was overly verbose. We want to keep the wiki as simple as possible.

Thanks lol, I incorporated the changes, let me know what you think.

EDIT: lol there was even more hiding, I had a look at those and they all seemed very reasonable and much better than the way it was already written / I had written it.

Not sure why you lost contributor attribution to this PR. Sorry ><

[fufexan]

LGTM, thanks!
