vnc connection doesn't work when building the image from Dockerfile

Hello,

I've build the Docker Image from Dockerfile, using the Dockerfile "Dockerfile.centos.xfce.vnc" cp Dockerfile.centos.xfce.vnc Dockerfile docker build -t marpe4k/centos-xfce-vnc:latest . The build finished successfull.

the container start worked with: docker run -d -p 5901:5901 -p 6901:6901 marpe4k/centos-xfce-vnc:latest

but vnc connection didn't work.

Doing the same steps with the Ubuntu image, there are no problems. What is going wrong with the Centos image?

Thanks, Martin
