Veyon
Download from GitHub
https: //github. com /veyon/ veyon/ releases/ tag/v4.8.0 (It is recognized as a link. Please join the parts, otherwise it won't let me post.)
(I use this version; it always works for me)
I always install it using the Ubuntu program installer. Configure and Test the keys
Extension
Install gnome-shell-extension-prefs
Disable desktop icons
Disable unused software
Install the package
sudo apt-get install gnome-tweaks
Open "Settings"
-- First tab "General"
--- Turn off "Animations"
It works like this here: if I don't follow this order, I can't get Veyon to work. It doesn't allow access to the keychain, which is basically what it needs to locate the machine.
In case of problems, I use ssh to stop the service with
sudo systemctl stop Veyon
and start it again with
sudo systemctl start Veyon
