-multiptr is not working properly

[vipul4work]

Support X11VNC_ARGS now

docker pull dorowu/ubuntu-desktop-lxde-vnc:latest
docker run -e X11VNC_ARGS=-multiptr ...

After using the -multiptr option, the local cursor disables, and there is a static cursor in the middle of the desktop, I am using the latest version of the docker, can you tell me if I am missing something, maybe some other parameter that goes along with multiptr ?
