Any movement on this? My students have figured out to move their non-school windows to their second screen...

I'm using v. 4.1.5

We have the dual screen box checked in the configurator.

I have successfully installed it but when I click veyon master or configurator nothing happens
What is the solution?

Thanks for providing the investigations and sharing the workaround! While scrutinizing the issue I spotted a problem in the build system leading to relevant x11vnc features such as the keyboard extension not being enabled at compile time. This will be fixed in 4.1.6.

Unfortunately we have to postpone this feature in order to get everything else done for 4.2.

Welcome to Veyon! Unfortunately it's currently not possible. We could implement this through professional services. Please contact support@veyon.io this could be an option for you.

Restricting access to a group such as teacher is the way to go so there seems to be a problem with the system or Veyon configuration. I assume the teacher users are member of a teacher group on both master and all client computers? Can you run

getent group teacher

and post the output here?

Please switch to the 4.1 branch or install cyrus-sasl-mingw-w64.

Have you solved the problem by now? Please see https://docs.veyon.io/en/latest/admin/configuration.html#authentication for more information on how to set up authentication in Veyon.

Ich arbeite mit windows 7 64bit

Hi Tobias,

I just described a similar issue here: [https://github.com/veyon/veyon/issues/455](link url)

Thanks in advance,
Julius

Ok,

As this rooms PCs are windows PCs, joined to an Active Directory, I used AD, and auth works fine (because my organization's AD master did it with me).
I guess I needed some more configuration in env and advanced parameters to make it work.
I didn't have to do that with linux, as my PCs were LDAP auth based, and in access control, I just had to choose "default (local groups and users)", and not LDAP, as I have to with AD joined windows PCs.

I didn't test further ldap conf, as I finally don't need it
Answer this post could help other people with the same question, though 😉

Yes, there's a configuration: "Disable the Swipe Feature of Windows 10"

For Windows 10 users with a touch-enabled device, it is possible to enter Task View by swiping left from the edge of the screen. To stop this from happening, you can disable this swipe feature by Windows group policy:

Computer Configuration > Administrative Templates > Windows Components > Edge UI ("Rand-UI" in German versions)

Using Linuxmint 19 Tara and XFCE desktop. I don't know what to examine but I uploaded the log files in my google drive, here is the link to it.

Welcome to Veyon!
First of all please consult our troubleshooting guide at https://docs.veyon.io/en/latest/admin/troubleshooting.html Can you see thumbnails of the clients in Veyon Master?

I suspect there's an issue with the new desktop duplication engine. You can try to stop the service, remove ddengine.dll / ddengine64.dll and restart the computer. Are you able to see the second screen of this client afterwards?
