Exactly, it looks like KDE NEON is not fully binary compatible with Ubuntu 20.04. I suggest to build the Veyon package on your own as described here: https://github.com/veyon/veyon/blob/master/README.md#veyon-on-linux

We'll launch a new pricing model this year which will also include licenses for personal use. Please contact sales@veyon.io to discuss further possibilities

The username/password of the teacher (or any other user using Veyon Master). The provided account has to exist on the remote computers (which should be default when working in an AD environment).

Are you using the same logon credentials on the 2 affected teacher computers as on the other working teacher computers? Can you check that the time is synchronized on all computers properly? Besides this I recommend upgrading to the latest version (as of writing: 4.5.2) on both teacher and student computers.

@itguy Hi, the idea of a background task sounds good to me. I'll give this a try.

@kunneljose https://github.com/veyon/veyon/blob/master/INSTALL https://veyon.io/download/

@issam Yes, just confirming Windows was set to not display last signed-in user. I have no other ideas at the moment.

@ocrozat Hello sir, Do you found the solution for this probleme, I have the same probleme, And I don't know how to fix it. When I try to connect with user name to an other PC , he refuse informations entred and message appear : tentative d'ouverture de session en utilisant des informations d'identification explicites

@marcus There is a button to the right of the search field at the bottom of the master window. Its purpose is to toggle display of powered-off or otherwise unreachable computers chosen for monitoring.

It seems that the slowness and freezes disappear after adjusting the LDAP update interval to 999 instead of 60 seconds .

@itguy You could instead copy the wakemon.bat file to a shared network folder then use 'Run program' to run the batch file from the shared folder: \\servername\sharename\veyon\wakemon.bat

SOLUTION: I created new set of keys and those worked. Old keys were from 09/2020, weird that those didn't work.

@tobydox said in Windows 10: log in function does not work: @erotavlas how does your Windows login screen look like? Do users have to enter their usernames? We have some information at https://docs.veyon.io/en/latest/admin/platform-notes.html#user-login Right, thank you.

@tobydox said in Windows 10: upgrade to latest version, control problem: The problem has been fixed in version 4.5.2 - if possible please upgrade and give us some feedback. I confirm, thank you.

The problem has been fixed in version 4.5.2 – if possible please upgrade and give us some feedback.

Are the student sessions virtual/remote desktop sessions? If so try enabling multi session mode (https://docs.veyon.io/en/latest/admin/reference.html#refmultisessionmode) and try the NetworkDiscovery add-on with session scanning enabled so it will access the Veyon Server instances at ports 111XX instead of 11100 only (which is the console session). BTW we'll publish a tutorial on how to work with remote/virtual desktop sessions in a few weeks.
