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.

[kind of solved] Nvidia Wayland Issues (feddit.de)

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. @[email protected]s 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

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

[–] [email protected] 1 points 8 months ago

I'm experiencing the exact same issue as the op, hence the comment. This is what helped me

Can you tell me how you did it? I just found an old guide for lwjgl 2.x.

[–] [email protected] 1 points 8 months ago

Realistically you should just need lwjgl-glfw version 3.3.3 or newer, and that should be it
