Other Wayland , labwc,sway : found 0 GPU's cannot create backend

I can start xorg/x11 without any problem.
But wayland fails to start with the error message in title.
The graphics card is:

vgapci0@pci0:1:0:0:    class=0x030000 rev=0xa1 hdr=0x00 vendor=0x10de device=0x1f03 subvendor=0x1462 subdevice=0xc757
    vendor     = 'NVIDIA Corporation'
    device     = 'TU106 [GeForce RTX 2060 12GB]'
    class      = display
    subclass   = VGA

Most Wayland compositors do not work under the proprietary Nvidia drivers as Nvidia implements a different rendering API than Intel & AMD.

The freebsd-nvidia drivers also not for me.

You need this for wayland with Nvidia.

Funny, I was under impression that Wayland devs actually target NVidia... Wayland requires something called graphics/egl-wayland... and that's NVidia stuff.

They actually do.
The problem is that the FreeBSD driver, in contrary to Linux/Windows, lacks the DRM module which is needed by practically all Wayland stuff.
Exactly this drm module has been ported from Linux to FreeBSD by ashafer in the GitHub I have linked.
