Hello, we use online scanning computers in our university library. On these computers, students log in with their ldap information. in the veyon program the lock screen does not precede the student login screen. However, it kicks in after student login. Veyonda lock screen
How can we bring it before the screen where students log in? So when the pc is turned on, the veyon lock does not come on the first boot screen. (we are using version 4.7) . Thanks bro.
