Deconz-rest-plugin: Deconz-Gui on a headless Raspberry

Created on 7 Jan 2020 · 5Comments · Source: dresden-elektronik/deconz-rest-plugin

Hello,
i got a Problem running deconz-gui on my headless Raspberry.

I got RealVNC running this way https://www.raspberrypi.org/documentation/remote-access/vnc/.
And i used the command vncserver

But when i try to start Deconz-gui this error occurs:

Jan 07 11:22:27 raspberrypi systemd[1]: Started deCONZ: ZigBee gateway -- GUI/REST API.
Jan 07 11:22:31 raspberrypi deCONZ[613]: Invalid MIT-MAGIC-COOKIE-1 keyqt.qpa.screen: QXcbConnection: Could not connect to display :0
Jan 07 11:22:31 raspberrypi deCONZ[613]: Could not connect to any X display.

Yes i get a working VNC-Session on 192.168.178.24 and 192.168.178.24:0 with realvnc

So you do get a desktop?

Both running on user root.

Unless you haven't explicitly changed anything, you're not root but user pi. Regardless, I'd try to run deconz from command line as follows:

sudo systemctl stop deconz-gui
sudo systemctl stop deconz
/usr/bin/deCONZ

Do you get a working VNC session? The error output states that you have issues with the .Xauthority file. Do you use seperate users for deconz and vnc connection?

Yes i get a working VNC-Session on 192.168.178.24 and 192.168.178.24:0 with realvnc (i dont know the difference tbh).
I also tried to open up the webbrowser and it doenst show up in realvnc.

I dont think so. Both running on user root.
I am a beginner, sorry.

Yes, i got a desktop. But i cant open the web browser or deconz-gui.

Did both commands and thats the result:

root@raspberrypi: sudo systemctl stop deconz
root@raspberrypi: sudo systemctl stop deconz /usr/bin/deCONZ
Failed to stop usr-bin-deCONZ.mount: Unit usr-bin-deCONZ.mount not loaded.

I tried to open Deconz afterwards. Still nothing happens or appears.
