Configuring weston/wayland for two displays

Hi @stefan.tx ,

we have tried a lot, but with the normal “dunfell-5” image weston does not work. We can’t set the OPTARGS. Here, you can see the logs:

The Command line is every Time:

Command line: /usr/bin/weston --modules=xwayland.so --log=/var/log/weston.log

Maybe we have to change the systemctl weston service ?
