First of all: I don’t have anything against Wayland. I just wanna play Minecraft occasionally.
I am running Fedora with KDE on some HP workstation with an Nvidia 2060 FE. I am using the proprietary drivers. With the next release of Fedora (and KDE), Wayland will be the only supported Display Manager (as of my understanding). I tried switching to Wayland, but I get some weird black stuttering in Minecraft making it completely unplayable. The bad thing is that with my friends GPU, a GTX 1050, it worked just fine. On my Laptop with just the integrated Graphics too.
Have you got any tips for me? I neither want to switch the distro nor the desktop enviroment, as I’m happy with how it is. I could imagine buying a used amd gpu, but I dont really want to spend a lot of money.
For now, I am just waiting and hoping they’re having it fixed in the release. ** Edit:** thanks for all the help. @Pantherina@feddit.des solution, forcing it to use xwayland made it better, but then i discovered that if I’m in fullscreen, it works perfectly fine, also without xwayland. It seems like a really dumb solution, and i’m not quite happy with it, but hey, if it works, don’t touch it.
tl;dr: In fullscreen it works just fine
You don’t have to worry. The folks at fedora have decided that the X11 session will remain in fedora 40 so you will be able to use X11 if you still face issues in wayland.
Edit : I was not clear enough. Want I mean to say is that the kwin-x11 and other required packages will be part of the fedora repo and people can just download them to enable the plasma-X11 session
Where did you see that? Are you sure you are not confusing it with fedora gnome?
At today’s FESCo meeting, we agreed on the following proposal:
AGREED: KDE packages which reintroduce support for X11 are allowed in the main Fedora repositories, however they may not be included by default on any release-blocking deliverable (ISO, image, etc.). The KDE SIG should provide a notice before major changes, but is not responsible for ensuring that these packages adapt. Upgrades from F38 and F39 will be automatically migrated to Wayland. (+5, 0, -1)
For additional clarification: this means that all users performing upgrades MUST be migrated to the Wayland session. They then MAY opt-in to the X11 session by installing a package for that purpose. We are explicitly not providing detailed technical implementation requirements here, but we expect all parties to follow the spirit of this decision when making technical decisions.
there’s a lot of stuff you can do, and you can end up with something usable, though not great, at least not in my experience. NVidia’s drivers are to blame, they don’t really work well with opengl and have lots of issues (and also regressions).
The 550 beta driver is ok-ish, steam flickers but I can play games. Drivers before 535 also somewhat worked, though it really depends on your GPU.
But I don’t think you will have it working acceptably without some work.
Here’s some pointers on stuff to try:
- check protondb for how other people got games to work, you can filter by your GPU.
- try running through gamescope or gamemoderun
- try the modeset=1 (and maybe fbdev) kernel parameters for nvidia drm
- and there’s tons of env vars and other things that can help, I couldn’t summarize them all here, but as a pointer:
XWAYLAND_NO_GLAMOR=1,WLR_RENDERER=vulkan,LIBVA_DRIVER_NAME=nvidia,GBM_BACKEND=nvidia-drm(for the drm above),__GLX_VENDOR_LIBRARY_NAME=nvidia - try the beta drivers, if those are available somehow (I’m on arch so they were easy to install), or just different driver versions in general.
The above is meant more as hints than something to copy paste, so use at your own risk. You can of course always just install a second DE with X11 and log into that for gaming and use your regular DE for everything else
None of these will help it, sadly. The flickering is an XWayland issue that’s still not fixed. Switching to native Wayland when possible would eliminate the flickering completely, however with games it’s not as easy.
In the case of minecraft specifically, you’ll require the newest version of lwjgl, which just got experimental Wayland support. Same for Windows games under Wine. 9.x had a native Wayland mode hidden in the settings
The usual xwayland flicker alternates last two frames (unlike op’s black flicker) and never occurred to me while playing a game, so op’s problem is probably something else
Roll back your drivers to 535 if you’re on 545. 545 is broken
Is 545 still the latest? That release was so awful it made me completely drop Nvidia and pick up an AMD card. Fixed so many issues
Like the other commenter I also had wildly flickering frames. Overwatch in particular was stuttering back to some previously buffered frame when the framerate was either below or above a sweet spot. I was also having issues with KDE Plasma bars that I assumed was a KDE issue, but they went away with the new GPU with no other software changes than swapping drivers. I was on a GTX 1080 which was still going strong with the games I played
I’m having the exact same situation with a 2060 super particularly badly when CPU spikes but not exclusively
Full screen hasn’t worked for me, but that’s probably because I’m using hyprland. Forcing it to run in xwayland solved the issue for you?
It is probably your NVIDIA driver. Version 545 has this kind of problem. Rolling back to 535 solved it for me.
