Monitor Clients goto sleep in Fullscreen demo

[SID SBD]

Hi anybody

Sorry for my bad English

My configuration is

Platform: Linux Ubuntu Server 18.04 Bionic + KDE Neon
Veyon 4.1.2

While I use the option "Fullscreen Demo", the student's monitors go to sleep

Why?

How can I solve it?

On windows dont happen this

Thank you

This is a known bug and discussed in https://veyon.nodebb.com/topic/100/broadcasting-and-screen-lock/7 already. We're working on a solution and hope to get this fixed in 4.1.3.
