Fedora 36 Planning To Run Wayland By Default With NVIDIA's Proprietary Driver

[bple2137]

Only thing keeping me on X is the nextcloud desktop app. It only shows a tray icon under X11.

I used Nextcloud on Wayland without any issue including the tray icon, though I globally enforced QT on Wayland with

QT_QPA_PLATFORM=wayland

It brings some other issues like junky window borders on GNOME or context menus misplacement, but if you do that on per-app basis where it works, it should be fine.
I can't remember trying it on Xwayland, but my experience with X apps on GNOME Wayland is that they all just work, including the tray icons.

Since the game is Xorg based on.

That's not how it works. In SDL games you can choose whether to use x11 or Wayland, so the game is not tied in any way to x11

I think that the problem with external monitors in Wayland when using the blob is only when you are running the hybrid setup. That is, let's say intel, iGPU is running the show and you plug your monitor into the Nvidia GPU, then that's when things go south, and that's probably why they still keep Xorg as default for hybrid setups. Last time I checked everything worked okay in Wayland for my hybrid setup **except** plugging in an external monitor. I don't think this is a problem if the Nvidia GPU is the primary display device, but I could be wrong, haven't tested that setup extensively.

That is not exactly an uncommon setup for a laptop though. For me at least I have 1-2 external monitors plugged in more often than not by a far stretch: My work laptop (Thinkpad P15 Gen1) has the external display outputs hooked up to the Nvidia Quadro GPU. I would love to run it in hybrid mode to save on battery when I do use it on the go, but I currently run it in full on nvidia-all-the-time mode due to stability issues (under XOrg even!). Battery life sucks as a result, but I probably use it docked or on the power brick 90-95% of the time anyway.

I'm on KDE Wayland Intel plus nvidia.

You are right that it does works properly, but only when playing the games through xwayland. If you force Wayland directly on the game, Nvidia Optimus doesn't support that and the game won't run on the Nvidia card.

Yeah, so this means that Wayland on nVidia using GBM is still broken in some ways.
- External monitor not working when using Hybrid setups (probably depend on which GPU it's wired to)
- Missing DMABUF support
- Not being able to select which GPU to use for native Wayland games

You'd expect from a multi-million company (which is about to acquire ARM) to put in a little more effort and resources getting an out of the box experience such as when using the Mesa drivers.

Looks like you have super old GPU that is working with Nouveau. If missing Vulkan can be considered "fine" lol. We are unlucky with our 9xx+ GPUs here.

Go ahead and continue making assumptions.

Hybrid graphics with nvidia work fine on X and Wayland now, I've been running Wayland exclusively since nvidia added support. I use Arch, btw.

In that case, I hope they detect that configuration and don't enable wayland by default on such systems. While I'm knowledgable enough to fix this kind of issues fairly easily (and I don't run Fedora), it is important to provide a good out of the box user experience. (As an example of this: a crash issue when selecting btrfs in the installer of Manjaro made me just say "nope, going for another distro, don't want to deal with this". Could I have worked around this? Most likely. But just going with plain Arch instead was easier.)

Everyone is thinking "wow, Nvidia has come a long way with linux". It is however also true that Fedora has come a long way with Nvidia. It's hard to know what is more remarkable: Nvidia supporting gdm, or Fedora supporting Nvidia binaries.
