Answer was I needed to use the IP instead of Hostname in the Configurator. now all good.

Hello,

i helped myself. Solution is resetting config through cli-command line.

You can lock thread now.

This might be related to an incomplete previous program update or incompatible versions of Veyon and the addons. I recommend uninstalling Veyon and reinstalling the latest version (+addons if desired).

Does this still happen with the latest 4.5.7 release? If so, do you have the chance to go back the releases step by step and report which version was the last one that works for you?

Veyon Master doesn't use the administrator account. The Veyon Service on client/student computers is running as the LocalSystem user which also doesn't require a profile to exist.

Hello, I am struggling to get veyon-server to start up automaically at the login screen of Ubuntu 20.04 before any user logs in. I am using the lightdm Display Manager and latest veyon from the ubuntu ppa. We have the ubuntu Desktop Environment for local use and the xfce Desktop Environment for use via RDP. So, once I am inside any user session and run the "veyon-server" command from a terminal, the veyon server starts and establishes a proper connection with the veyon master. Before and after that, I just see the orange screen... I have searched quite a while now and found several related posts to this topic, but this seems to be the newest one. Please tell me if I should post any logs or where I could check proper configuration. Thank you in advance.

After much time spent trying to get veyon to work on my Ubuntu 18.04 lab, and many days and weeks with not much support, I decided to end the suffering and move on. I did find an affordable paid option that I am using right now and it works great. Not only that but I did have a few issues after first install and the developer scheduled a zoom meeting with me on the same day of purchase and we got it all ironed out.

So, if you are using Ubuntu and like me are stumped. If you are looking for an affordable solution, I can recommend Classroom Spy at classroomspy.com. Does the same thing as Veyon and I think I paid a 1-time cost of $699 for 25 computers.

@lmoellendorf Can you try passing -DWITH_PCH=OFF to CMake? Which version of CMake are you using?

@gparent DNS looks OK. Try checking VeyonMaster.log, if it contains any clues.

Based on this script, the mac format could be xx-xx-xx-xx-xx-xx. But I think it is needed only for WOL.

Thank you very much for your interest in sharing your work! For the time being, I suggest to open an issue at https://github.com/veyon/docs/issues and attach the document there so we can review it. Even better would be to integrate it into the official documentation, e.g. by adding an Ubuntu-specific chapter in the admin manual. What do you think about it?

@tobydox Thank you for the explanation. I use "Show notification on remote connection".

@kelfka Hi, I haven't tried it myself yet, but maybe you could try opposite approach. Demostration mode should let you stream the screen from one PC (smart board) to other clients (kids)... You start the action from Master PC... kids do not have to do anything...

Manual:
You can use the demonstration mode (demo mode) to start a presentation. In this mode, the content of your or a student’s screen is broadcasted to all computers and displayed in real time. You can choose between a full screen and a window demo.

Hello @erich,

Veyon Master does not require any administrator rights to run. When trying with a non-admin user, did you try a local or domain user? In case of domain users, did you properly prepend the domain, i.e. MYDOMAIN\user? Did you also disable the "Perform access control" option in the master configuration (https://docs.veyon.io/en/latest/admin/reference.html#behaviour)?

@tbuller Probably the download somehow failed? I just downloaded the file and it has a size of around 1.8 MB. Alternatively use our PPA so you benefit from automatic updates and better dependency resolving upon installation.
