X11 is deprecated, it’s been removed from RHEL, and hasn’t had dedicated maintainers for years. You might as well switch to Wayland (and xwayland if needed) now, it’s not really the case that you have an option.

Just a head up to be careful with 7900 XTX if you do plan on getting an AMD GPU like other people on here are suggesting.

When I purchased 7900 XTX, AMD doesn’t offer me any way to control the fan speed on 7900 XTX and it always get stuck on 5% speed. I literally tried everything from using hwmon mode setting to manual (it stuck on auto and refuse to switch to manual), literally modifying the AMD GPU driver in kernel to forcibly set the manual mode for fan speed, it doesn’t work and instead it locks up the Kernel, and tried literally every application that exists for setting fan speed on 7900 XTX.

I tried to contact the manufacturer to refund me, they refused to pay me back in full and want me to reduce what I get back, I paid $1000 for it, they want me to pay $100 shipping and to only be qualified to receive $400 from them. I ended up keeping the 7900 XTX and basically went nuclear on fixing the GPU. This was literally within 1 week of receiving the GPU mind you. AMD is ranked far below Nvidia after my absurdly negative experience with them and I would rather go with Intel than AMD at this point and that is saying a lot, because it’s not only my GPU that is a problem, but it also with their software and driver like ROCm that NEVER worked, ever.

I created a plastic strap via 3D printing on top of the GPU and create a negative pressure fan to cool it down, it can stay under 50 degree Fahrenheit at 100% utilization.

Wayland is the future. But I live in the present so I use X11 :)

Just kidding I use Wayland on my work laptop (and maybe I should revert it to X11?! I have an issue with switching to an external monitor). I have both installed but overall I think I’ve had fewer issues with X11 than with Wayland.

I’m hoping one day soon it’ll be amazing but until then I see everyone’s pushing for it and in my experience so far it’s not ready yet.

I’m using Arch, Wayland, AMD GPU, Discord, Steam (Proton, so xWayland) for playing. I don’t remember when I switched to Wayland, might be even more than a year.

I remember that I liked something about configuration and internal logic but mostly, for me, it just works. I don’t see much difference from purely user perspective.

I love Wayland but I’m not using Nvidia. I really hope th3y figure that Nvdia stuff out soon because it’s such a roadblock to many people when it comes to Wayland

I haven’t used Nvidia since I switched to Linux 8 years ago. That’s what my computer at the time had, and it definitely influenced the hardware I chose going forward (I switched to using AMD GPU’s).

The X11 developers have moved onto working on Wayland, and I find my computers are more performant under Wayland. However, my use-cases don’t require CUDA or anything else that Nvidia provides.

In the end, use the tool(s) that get the job done. I’m not going to say “switch to AMD & use Wayland,” it’s not my place to do that. X11 is fine until the Wayland experience on Nvidia improves.

Little late to the party, but I’ll chime in. I have a 3080, and for the most part, Wayland works, but there are a few problems that keep me from using it as a daily driver. G-Sync doesn’t work at all, and when I put my PC to sleep, upon wake I end up needing to do a full reboot because of severe graphical issues. When it is running though, it’s pretty smooth, with only a few graphical issues here and there. I still daily drive X11 though until the major bugs are fixed.

In your situation, I would say to stick with X11. I’m still using X11 for gaming, but Wayland for most other things. Maybe try Wayland again in a few years. And when it’s time to buy new hardware, maybe avoid Nvidia.

If you want to have another go at getting it working, check out what the Arch wiki says for KDE:

If you are an NVIDIA user with the proprietary nvidia driver, also enable the DRM kernel mode setting. If that does not work, too, check the instructions on the KDE wiki.

As for the question of security, I want to emphasize that X11 is not increasing your risk of getting hacked. If one of your applications is compromised, then X11 acts as one method by which an attacker could further their attack or extract information, but other methods would usually be easier for an attacker. You could use flatpaks or firejail to mitigate those other methods, but only after you’ve done that would Wayland provide a meaningful security benefit.

This is a sore point. I understand that Wayland is the future, just as people adopt laptops instead of desktop machines.

Many years ago, I used Opera browser - I learned to close tabs using MOUSE gestures… so instead of clicking on a little 'x to close a tab, I could press the RMB and draw an L shape.

With X11 (initially with the software Easy Gesture and later on with KDE’s own Custom Shortcuts) I was able to do the same thing - but for ALL desktop apps.

So now, drawing an L does Ctrl+W - and I have dozens more gestures to do not only keyboard shortcuts, but also commands and scripts…

So just putting it out there that X11 isn’t only for NVidia users or gamers…

If gaming is your focus I would suggestedtio stick to x11 for some time. If you want to try an arch based distro I would suggested to stick with archo orendeveross. Thy are for the normal userwazy easier then pure arch.I

NVIDIA has been shit on wayland for a while now, wayland is coming along nicely though and there’s already quite a bit happening in terms of expensions; but unless you need wayland for something there’s no real need for it (and you can get wayland apps working on X11 just fine). The big thing right now is that we’re in a transition period where we need to go from one ecosystem with tons of well used extensions (like xinput) to one where these extensions are still being developed.

What I’d say is that if you just stick to Gnome or KDE you won’t have to worry about which one you’re using yet, and if you have problems with wayland just stick to X11 until those get resolved. I’m in a similar ballpark where I’m still on X as I am waiting for several parts of the wayland ecosystem to mature (mainly nvidia support specifically for certain laptop configurations and tiling WMs (yes there’s options, but I have multiple problems with most of them))

Specifically with KDE and Arch, if you installed the meta package including the sddm display manager, make sure you’re using sddm-git and not the stable release (19.x I think) because the stable version of sddm doesn’t support Wayland. That could be why you’re seeing a black screen, the drivers shouldn’t be that bad. KDE is in the process of transitioning to being Wayland by default, some things are still WIP and you may have to account for that on bleeding edge distros like Arch. That’s the fun thing about Arch, not only does it not stop you from shooting yourself in the foot, it cheerfully loads the gun for you.

I had many issues running Arch+Wayland+nvidia because, as a long-time i3 user, I figured that migrating to Sway would be the best choice based on so many people in the community talking about it. I tried moving over several times, every few months to see if the experience had improved but each time I got frustrated with how terrible and buggy the environment was.

Trying out Hyprland was a complete game-changer. I’ve been running it full-time for about 2 months and it’s completely stable, supports everything I need to run, and is more efficient: the battery on my laptop lasts about 30% longer compared to my i3/picom/X11 setup.

So yeah, I highly recommend Hyprland if you’ve tried sway in the past and didn’t get anywhere with it.
