To set up default DE for the VNC server, you'll need to modify/re-create the file 'xstartup' on the directory '~/.vnc'. This script will be automatically executed when the VNC server is running.

mv ~/.vnc/xstartup ~/.vnc/xstartup.bak
nano ~/.vnc/xstartup

there is no xstartup in vcn

 

Hello,
You don't said so much about your system version, etc.

I don't know if this would realy help you, but that what I did to get VNC Server with Debian 11.5 with graphic interface installed.
It is fully functional.
I used part of this one :

Code:

https://techviewleo.com/configure-realvnc-server-and-client-on-debian/

• 0.1. Log in as root or run
  
  Code:

  su -

  
  
• 0.2. Or if no "root" access, add "sudo" in front of each command for the allocation of rights.

1. Start the download of the current version (2022-10-11)
   
   Code:

   wget https://downloads.realvnc.com/download/file/vnc.files/VNC-Server-6.11.0-Linux-x64.deb

   
   
2. Start the installation of the *.deb :
   
   Code:

   dpkg -i VNC-Server-6.11.0-Linux-x64.deb

   
   
3. Enable both services:
   
   Code:

   systemctl enable vncserver-virtuald.service
   systemctl enable vncserver-x11-serviced.service

   
   
4. Start the two services :
   
   Code:

   systemctl start vncserver-virtuald.service
   systemctl start vncserver-x11-serviced.service

   
   
5. Activate the "Enterprise" license: (2022-10-11)
   
   Code:

   vnclicense -add xxxx-xxxx-xxxx-xx

   
   
6. Launch "RealVNC" :
   
   Code:

   vncserver

   
   
7. Connect with a VNC viewer with the distant IP / domain name
   By defaulf the port is (have to be changed after the first connexion) :
   
   Code:

   5900

   
   
8. After the first connexion, I did all setting I need with VNC Server.

Vincente.
