Trying to run KDE 6 Plasma with Wayland....

Don ZioMario · Jul 23, 2024

Thanks. It does make difference. Instead I see a big difference when I change the value of "QT_QPA_PLATFORM".
Actually I have :

Code:

export QT_QPA_PLATFORM=minimal

but I read that it can assume different values. At the moment I don't know what they are. Can you tell me all the values that I can use ? I will try them one by one. Thanks.

Don ZioMario · Jul 23, 2024

I've looked for what caused this error for months :

and finally I got it. It is :

export QT_QPA_PLATFORM=xcb

Don ZioMario · Jul 23, 2024

export QT_QPA_PLATFORM=vnc

is interesting :

It says "the bound address is already in use" because I'm using a vm like this :

Code:

/usr/sbin/./bhyve-win -S -c sockets=1,cores=12,threads=1 -m 12G -w -H -A \
-s 0,hostbridge \
-s 1,ahci-hd,/mnt/$vmdisk4'p2'/bhyve/img/FreeBSD/FreeBSD-141.img,bootindex=1 \
-s 8:0,passthru,2/0/0 \
-s 8:1,passthru,2/0/1 \
-s 8:2,passthru,2/0/2 \
-s 8:3,passthru,2/0/3 \
-s 11,hda,play=/dev/dsp,rec=/dev/dsp \
-s 13,virtio-net,tap14 \
-s 14,virtio-9p,sharename=/ \
-s 29,fbuf,tcp=0.0.0.0:5914,w=1600,h=950,wait \
-s 30,xhci,tablet \
-s 31,lpc \
-l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI_CODE.fd \
vm0:14 < /dev/null & sleep 2 && vncviewer 0:14

but the busy port is not 5900,but 5914...

seatd - Service is enabled

Plasma cannot use seatd without https://github.com/CTSRD-CHERI/cheribsd-ports/commit/02e468a397ad

Plasma requires ConsoleKit2 session, so prepend ck-launch-session,like :

https://cgit.freebsd.org/ports/tree/x11/plasma5-plasma-workspace/files/startplasma-wayland.sh

Anyway,I'm trying with :

Code:

export LIBSEAT_BACKEND=consolekit2

sddm - Wayland session is visible but doesn't start. X11 is visible and KDE6 starts.

please disable sddm,it causes problems.

also change the last line to use exec and dbus-launch --exit-with-session
see if that helps

exec ck-launch-session dbus-launch --exit-with-session startplasma-wayland 2> startplasma.log

my start script :

dont export XDG_RUNTIME_DIR

on 14.1 its automatically created and exported

And what happened after you updated the permissions? You did do that, right?

Re: Question: setting up Plasma Wayland session

in particular,point 2 :

[2] CheriBSD added libseat support to KWin in their ports/ tree. That may
be more stable than relying on consolekit2 to behave like logind or
Plasma/Wayland not to expose consolekit2 bugs which don't affect Plasma/X11.

I did nothing because I'm not sure about what to do.

14.1 xdg runtime dir location

Code:

/var/run/xdg/username

where username is your username
you dont need to set export the XDG_RUNTIME_DIR

its automatically set to your username with the correct permissions and exported

if you comment out export XDG_RUNTIME_DIR
and reboot the vm and run

Code:

printenv

you will see its exported

Code:

XDG_RUNTIME_DIR=/var/run/xdg/djwilcox

Don ZioMario · Jul 23, 2024

like this ?

What we have here ?

1) wayland and wayfire works
2) kde 6 on top of xorg works :

so what ? can the conclusion be that if wayland + kde 6 does not work is because there are bugs ? because if we take only point 1 we can assume that Wayland works. If we take only point 2 we can say that kde 6 works...they don't work together,so logic wants that in this case cause are bugs or some unfinished work between some relationship that bind them.

NapoleonWils0n · Jul 23, 2024

it will be easier to figure out what the issue is
if you dont export so much stuff in your script

start with exporting a few variables

Code:

#!/bin/sh

export XDG_CONFIG_HOME="$HOME/.config"
export XDG_CACHE_HOME="$HOME/.cache"
export XDG_DATA_HOME="$HOME/.local/share"

export QT_QPA_PLATFORMTHEME=qt6ct
export LIBSEAT_BACKEND=consolekit2

dbus-launch --sh-syntax --exit-with-session startplasma-wayland 2> startplasma.log

and then see whats needed,
most desktop will automatically set what they need most of the time

you probably dont need this

Code:

export __GLX_VENDOR_LIBRARY_NAME=nvidia

thats the code i gave you for a davinci resolve fix

the idea of not exporting all those variables is to test if any of them are causing the issue
then just add them back one at a time and see if it works or breaks

at least that way you will know if they are the problem or you need to look elsewhere

NapoleonWils0n · Jul 23, 2024

because if we take only point 1 we can assume that Wayland works.

no assumption needed wayland works on Freebsd
ive been using it for the last 6 months with wayfire, labwc, hikari and dwl

exporting variable like QT with the wrong settings can stop stop wayland from running
for instance xcb is for X11 and not wayland

thats why mention not exporting lots of stuff in your script

i know this from getting davinci resolve to work in a linux jail on freebsd
resolve is a qt application

i dont export any "wayland" settings

~/.zshenv

Code:

# xdg directories
export XDG_CONFIG_HOME="$HOME/.config"
export XDG_CACHE_HOME="$HOME/.cache"
export XDG_DATA_HOME="$HOME/.local/share"

# qt5
export QT_QPA_PLATFORMTHEME=qt5ct

Code:

printenv

Code:

WAYLAND_DISPLAY=wayland-0
XDG_CACHE_HOME=/home/djwilcox/.cache
XDG_CONFIG_HOME=/home/djwilcox/.config
XDG_DATA_HOME=/home/djwilcox/.local/share
XDG_RUNTIME_DIR=/var/run/xdg/djwilcox
XDG_SESSION_TYPE=wayland

you can see the XDG_SESSION_TYPE is set
as well as the WAYLAND_DISPLAY

come on man. I'm not talking in absolute way. I mean that it is working now for me,in the same v. machine where KDE 6 also works,so they are WELL CONFIGURED if considered separately.

you can see the XDG_SESSION_TYPE is set
as well as the WAYLAND_DISPLAY

I've already tried to include and exclude variables,but I haven't yet touched the wayland settings...good idea to play with them...

NapoleonWils0n · Jul 23, 2024

so kde works on x11 with no missing fonts or anything like that
and wayland is working with wayfire

you have all the needed kde package installed

in your startup script you are

1 - exporting variables
2- running dbus-launch
3 - startplasma-wayland

so which of those 3 things might be causing the issue

so if you rule them out one by one you might track down the cause of the issue

if you commented out all the exported variables and then uncomment them you could could rule that out
then move onto the dbus command and the different ways you can use that

then finally you could see if the issue is with the startplasma-wayland script
i did see people mention issues with it in the past on the forum

NapoleonWils0n · Jul 23, 2024

have you looked at the startplasma-wayland script
to check if it works with kde6

if it has any hard coded paths to kde5 or anything like that

Don ZioMario · Jul 23, 2024

I've added these lines to /home/marietto/.shrc

Code:

export XDG_CONFIG_HOME="$HOME/.config"
export XDG_CACHE_HOME="$HOME/.cache"
export XDG_DATA_HOME="$HOME/.local/share"
export QT_QPA_PLATFORMTHEME=qt5ct

and this is what happened :

Now I can't login inside the vm anymore.

NapoleonWils0n · Jul 23, 2024

are you running freebsd 14.1

i did suggest

Code:

#!/bin/sh

export XDG_CONFIG_HOME="$HOME/.config"
export XDG_CACHE_HOME="$HOME/.cache"
export XDG_DATA_HOME="$HOME/.local/share"

export QT_QPA_PLATFORMTHEME=qt6ct
export LIBSEAT_BACKEND=consolekit2

dbus-launch --sh-syntax --exit-with-session startplasma-wayland 2> startplasma.log

with consolekit2 and qt6ct

you can export the variables one by one to see what the issue is
