You have to change the service configuration (on the target machine) so that it uses Active session mode. This will make the Veyon Service launch the Veyon Server for the currently active session, no matter if it's a console or an RDP session. If you require support for multiple RDP sessions, consider activating the Multi session mode and using the NetworkDiscovery add-on to see all (even dynamically changing) sessions in Veyon Master.

@mscdaddy30 EDIT: So I figured out how to solve this problem! I installed Veyon via the apt command from the repository and this version had the issue with the service not staying between login sessions. Once I downloaded the .deb file from the website and installed it, the problem went away! The only criticism I have is that there is not a way to remove the "master" portion of the install. Fortunately, the Master that shows up in the start menu requires elevated privileges so the kids cannot access it.

@nishizhen1234 How to compile vs project? I found It requires many dependencies

Bonjour, Il se base sur l'adresse MAC pour le démarrage des machines, mais à ma connaissance, après c'est le nom ou l'adresse IP. Et chez moi sur un parc machine de 250 avec 600 profils utilisateurs qui tournent sur les postes, il y a des soucis avec les noms d'hôtes qui se mélangent même après un nettoyage du cache. Je n'en sais pas plus sur les conditions techniques précises, si ce n'est que plusieurs prestataires de maintenance en sont arrivés à la même conclusion alors qu'ils auraient souhaité ne pas passer en resa d'IP... Le sujet m'intéresse grandement, ainsi que les possibilités de mettre en place un fonctionnement adapté à un emploi du temps des groupes d'utilisateurs de l'AD... Bon courage

May you have some hidden special (e.g. UTF-8) characters in your file or some kind of encoding or newline problem? I was able to run the command with the given example file without any problems

That's indeed a very special issue we've never seen before. First of all it looks like you're running Windows 7 which unfortunately is not supported by Veyon any longer. Does the issue appear with other Win10 computers as well? Does the affected computer have a special display configuration (color depth, resolution etc.?) Which version of Veyon is installed on the computer?

@tatanas Any chance you can test with the internal VNC server and disable the external UltraVNC server instance temporarily? That would allow us to figure out whether your issues are related to the external VNC server feature in Veyon.

@walery I removed version 4.7.0 Installed 4.6.0 Everything works now.

@zeltron80 What do you mean by this statement, can you be more descriptive please.

Any news here?

@benoitfouc You need to open veyon-configurator and switch the View to Advanced. Then you go to the Service tab and there is the option "Hide tray icon".

I knew better than to install a .0 version of a program! Going back to the earlier one for now. . . I need it working!

@tobydox nice. This solved an issue I've been struggling with for quite q few days:) thanks!

@hitzl Hello, Did you manage to make it running ? Thanks, Delvasse
