KDE panel missing on tigervnc vnc session
So I found 2 solutions for me - if anyone stumble over the same question.
with Tigervnc or Tightvnc
with x11vnc
The difference between both is that 1. starts its own x11 server and 2. connects to the existing desktop. With 1. I can setup any screen resolution that I want and start as many as the hardware can handle - didn't red about any limitations.
1. in the ~/.vnc folder appears a xstartup file after the first start of tigervnc that has to contain the following content in order to start a kde plasma x11 session:
#!/bin/sh
# Run a generic session
if [ -z "$MODE" ]
then
xsetroot -solid grey & #set the background picture
export XKB_DEFAULT_RULES=base & #both should be needed for keyboard signals
export QT_XKB_CONFIG_ROOT=/usr/share/X11/xkb &
# export $(dbus-launch) &
# exec startplasma-x11&
# kstart5 plasmashell &
konsole & #starts konsole (kde terminal)
firefox & #starts firefox
ksysguard & #starts the kde system monitor
# xrandr --dpi 144 & #
kstart5 plasmashell & #adds a task bar to the windows
dbus-launch startplasma-x11 #starts the actual window + Dolphin
# /opt/kde/bin/startkde &
fi
All the out commented Options (and many more are tryouts with a bad or not result at all)
vncserver :1 -depth 24 -geometry 1920x1080
starts the server in FullHD
and vncserver -kill :1
kills it (1 stands for sessions and increment the more you run the command before)
I can connect to it with remmina gui client with ip and port - f.e. 192.168.1.4:5901 (standard port, you find your server ip with ip addr
)
There is still no task bar and still no background desktop options available - but it works and I can move and resize windows and start new windows with the terminal - If you find a solution for that - am happy to hear bout it :)
2.
Is pretty easy/fast, just installing x11vnc (sudo pacman -S x11vnc
)
and starting it on the server with x11vnc -many -display :0
Than connecting with remmina client and the ip (no port) (f.e. 192.168.1.4)- boom done - picture of the original monitor. (in my case just hd resolution - but with desktop and taskpanel)
If I skip the command -many, the session is just available for one connection and ends after I disconnect the vnc client and has to restarted every time i want to connect. With many it stays. Starting the x11vnc automatically after a reboot is done with the following:
I have lost some hours on this. I think it is not a good idea to start x11vnc as root. This [email protected]
- on Arch Linux this folder is at /usr/lib/systemd/system/
- just create a file with [email protected]
and include the following content.
[Unit]
Description=VNC Server for X11
Requires=display-manager.service
After=display-manager.service
[Service]
Type=forking
ExecStart=/usr/bin/x11vnc -rfbauth /home/user/.vnc/passwd -ncache 2 -forever -shared -bg -display :0
Restart=on-failure
RestartSec=10
User=%I
[Install]
WantedBy=multi-user.target
can be started once with
systemctl start [email protected]
where you can change "user" to your user and it can be started after boot automatically with
systemctl enable [email protected]
and it will never fail (maybe the lines about restart can be omitted).
Yeah - thats it :)
EDIT:
I tested it on many arch linux servers now and for stability reasons
one should use the git version (yay -S x11vnc-git
instead of yay -S x11vnc
) because by compiling it on the specific computer the compiler optimizes it perfectly for the installed system. Not necessary in most cases but for some hardware it is necessary.
Also the -ncache 2 flag speeds up/safes up bandwidth to the vnc server by just sending the difference to the previous picture but is optional and works fine without it if bandwidth doesn't matter.

I want to gain VNC access to a tigervnc server. Both laptops runs with ArchLinux sddm KDE xorg (not wayland) and it took me a day to get the server running and an Dolphin is opening - just nothing else. my xstartup file contains the following:
#!/bin/sh # Run a generic session if [ -z "$MODE" ] then xsetroot -solid grey & #has impact on the background export XKB_DEFAULT_RULES=base #no impact export QT_XKB_CONFIG_ROOT=/usr/share/X11/xkb #no impact kstart5 plasmashell & #no impact konsole & #is opening firefox & #is opening xrandr --dpi 144 & #see no difference dbus-launch startplasma-x11 #this is what moves the needle rn :) fi
I start the server with
vncserver :1 -depth 24 -geometry 1920x1080
and I access the server with the remmina client, the google vnc viewer and KRDC with ip:port and the vnc transmission has a pretty good look and reaction time is nice. Just I can't right-click on the desktop and there is no task bar/the plasma panel is missing.I can start applications with the terminal like firefox e. g. just not the plasma panel somehow. The logout screen works fine too and I can logout and login with pure perfect graphics and animations.
So my question is: How do I get the plasma Panel + Desktop shown on the vnc server or how can I connect to the original desktop on tty1?
(If I access the server laptop directly it works fine, the panel shows up and it runs smooth. I also got a gnome vnc server up and running in seconds - just I fell in love with KDE and it actually runs much smoother/faster/reactive than gnome via vnc)

Igor Stoppa almost 3 yearsI tried the Tigervnc option and works quite well. I am not sure what you meant about taskbar and desktop background, because I can see them. I'm on Ubuntu 21.4

Ingo Mi almost 3 years@IgorStoppa Nice, thanks for your feedback - would be great if it is fixed. Will try it out at times and correct the answer accordingly.
