Wayland not working

[h-2]

I think that I installed all the right things:

# pkg info | grep nvidia
linux-nvidia-libs-550.54.14    NVidia graphics libraries and programs (Linux version)
nvidia-driver-550.54.14        NVidia graphics card binary drivers for hardware OpenGL rendering
nvidia-drm-515-kmod-550.54.14  NVIDIA DRM Kernel Module
nvidia-drm-kmod-550.54.14      NVIDIA DRM Kernel Module
nvidia-settings-535.146.02     Display Control Panel for X NVidia driver
# dmesg | grep drm
[drm] [nvidia-drm] [GPU ID 0x00000a00] Loading driver

17 1 0xffffffff83695000 7c050 drm.ko
# lh /dev/dri

lrw-rw-rw- 10 root 10 Mar 22:13  renderD128 -> ../drm/128

But if I try to start a wayland session, e.g. plasma-wayland, it doesn't work:

No backend specified, automatically choosing drm
kwin_core: Could not determine the active graphical session
kwin_wayland_drm: failed to open drm device at "/dev/dri/card0"
kwin_wayland_drm: No suitable DRM devices have been found

Am I missing something?

Thanks for your help!

As of 550 you need to set hw.nvidiadrm.modeset=1 in /boot/loader.conf. Did you do this step?

Note that there are also a few outstanding issues with the pkg, so you might want to build from ports if you haven't already. That's mostly for multigpu setups so that might not affect you.

Thanks for the quick reply!

Yes, I have that!

I'll give it a try, although, as you said, I don't have a multi-gpu setup.

You're trying kwin wayland? Is that even supported on FreeBSD? Last I heard it was not stable and was a WIP?

You'll have to share dmesg/logs/etc for me to know what's going wrong.

I didn't know kwin-wayland was problematic :o I am actually aiming for sway, but I had thought that Kwin was the more established thing, so I did my experimenting with that.

I will give sway a try, and report back!

I managed to get sway working with the 570-series of the driver!

This is how I start it: dbus-launch --exit-with-session ck-launch-session sway --unsupported-gpu.

It does not work with SDDM (it lists sway, but after logging in there is only a black screen with a white mouse cursor).

I haven't been able to get plasma-wayland working (neither directly, nor through sddm).

With the most recent pkg upgrade, sway no longer loads. It runs without crashing, but no desktop loads. I still see the VT, although I cannot Ctrl+C. I can switch to a different VT and kill sway, though. This is the log:

I am not sure if any of these are "new", though.

I think this drm-kmod change is relevant. drm-kmod has issues with the primitives needed for explicit sync, which it looks like sway is tripping over.

[amshafer]

The eglDupNativeFenceFDANDROID error you linked above is actually separate from drm-kmod's problem, this will be fixed in a future driver version (version 580).
