Ich habe seit gesern nach meinem neustart meines Raspberry PI 4 probleme mit meinen Conbee2.
Ich habe sogar schon versucht einen neue version einzuspielen, habe geooglet.
Danach war auch erst eine Firmenversion angezeigt worden. Ich konnte aber keine Schalter/Stecker oder was anderes Anlernen. Reboot und es war keine mehr da.
habe dann noch weiter gegoogelt.
bin dann über das hier gestoßen aber ich komme einfach nicht weiter. Habe auch schon Phoscon-App neu installiert auch keine änderung.

qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin “xcb” in “” even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
I don’t understand your procedure.
You have a raspbian with desktop, you can’t connect to phoscon but if you plug Screen/mouse and keyboard all is working ?
You are sure you don’t have 2 sessions running ? It can happen if you have an headless OS and use VNC, as your OS is headless a wrong procedure to use a VNC client can trigger a new session.
And if you unplug screen/mouse and keyboard, all is still working ? So it’s fine ?
I installed everything with a monitor connected and set it up using the desktop interface.
Everything worked fine, then I disconnected the monitor.
I accessed the system via VNC (Remote VNC), and everything was running smoothly for about six months.
During that time, there were some OS updates, both through the desktop and the terminal.
Two days ago, while using the desktop via VNC, the deCONZ app opened in full-screen mode. So I connected a monitor, adjusted the deCONZ window (minimized it slightly), and afterward, there was no access to the deCONZ stick once I disconnected the monitor again.
Now, when I connect the monitor, everything works fine again.
How can I disable the dual-session behavior, if that’s the cause of the issue?
So all seem fine, and plug/unplug devices can’t change something for me. If you are using the native VNC server on a desktop OS, can’t be a session issues.
Can try
ps ax | grep deCONZ
This command will show how many instance you have (but on this session)
