HI

This is a report on successful startup of KDE6/plasma6 on wayland on Nvidia RTX3060

All I did to start KDE on Wayland on Freebsd 16 WAS:

#1 build Nvidia 580.105 drivers and install them.
#2 Build kde6/Plasma6 selecting and including all wayland options in the ports as I built them.
#3 build and install and run the /usr/ports/sysutils/seatd service.
#4 run " exec dbus-launch ck-launch-session startplasma-wayland "

ISSUE with missing cursor:

the cursor is not visible on the Nvidia display.
this problem occurs on linux as well and is well known.

Solution is to set variables

export WLR_NO_HARDWARE_CURSORS=1
export KWIN_FORCE_SW_CURSOR=1

in $HOME/.profile
 
I installed with cmd "doas pkg ins kde".
started it with "exec dbus-launch ck-launch-session startplasma-wayland".
my laptop has Intel UHD Graphics [Integrated] card.
it runs ok.
chrome crashed!!!
There are some issues on system information widget which i haven't sorted out yet.
cursor is working.
so is audio.
sleep works too, except wifi is disconnected n has to restart with "doas service netif restart wlan0"
 
I found out that konqueror crashes too.
chromium was able to start later. but, chromium, librewolf and waterfox could not be minimized.
I have never tried on 15, sorry.

Will it work on 15.0 ?
Because nvidia does not support wayland.

I tried KDE6/Wayland on two additional machines with FBSD 15-p1 one kabylake cpu with a quadro p2000 GPU , system panics and reboots .
And also on one AMD threadripper with RTX4000 , were machine does not Panic but fails to start desktop with som EGL graphics errors .
that machine is using Nvidia 580.95 drivers from the quaterly repo . so i may try to upgrade to later Nvidia drivers shortly.

x11/nvidia-driver + x11/nvidia-kmod alone may not work well for Wayland (possibly depends on compositor).
As far as I know, to use Wayland, usually graphics/nvidia-drm-*-kmod{-devel} is wanted. "*" here would depend on the version of base FreeBSD version.

And a correction. Not "nvidia does not support Wayland", but "Wayland does not support nvidia well". This is similar to Xorg, which xorg-server does not look for nvidia proprietary driver (except graphics/nvidia-drm-*-kmod{-devel} which runs via default modesetting driver) without additional manual configuration.

Note that nvidia drivers does not support all patterns of protocols Wayland assumes. But supporting basically EGL for Wayland.

Beware! Current in-tree version (on latest branch) of "-devel" variant is at 590.48.01. And starting from 590 series, nvidia dropped supports for GPUs older than Turing generation of architectures.

So to use Quadro P2000, you need non-devel variant (master port at 580.119.02 on latest branch) of drivers.

You can see which GPUs are still supported here.

And you can read HEADSUP I've posted to freebsd-ports ML here.
