I have created an environment variable in the operating system with a value equal to 2
SET VEYON_SESSION_ID = 2
And also in the veyon-client environment.
veyon-cli config set Service/VEYON_SESSION_ID 2
My session ID is two
SESSION NAME USER NAME ID STATE
services 0 Desc
rdp-tcp # 2 administrator 2 Active
console 3 Conn
rdp-tcp 65536 Listen
And in no case have I managed to make the screen that shows to the students the session in which the teacher works.
I have also test with the new version of Veyon 4.4.0
I would like to remind you that both the students and the teacher are working on their own virtual desktop connected by RDP, that is, they are all in session 2 of their own virtual desktop.
