@vkovelkar I just built and tested ubuntu-xfce with no problem. What are the commands that you are using to build the image?
@danchitnis I download whole master branch and I try to build the image but am getting above error. command : " docker build -t ubuntu:xdp ."
This is not the correct command. Are you following this? It is best to build it in Linux. If you still have errors during the build, then you have to upload the docker build logs here. Another option is to pull the image, and then update it inside the virtual environment like normal ubuntu.
I see the same issue with the Ubuntu version on dockerhub. After login there is a black screen and mouse pointer, but nothing else.
Same with the Fedora image. On the same host with the same RDP client the image from danielguerra69/ubuntu-xrdp runs fine. I'll try tomorrow with another host.
Not sure what is going on. On my machine with the new Docker doesn't work at all. On my other machine with old Docker runs but has your blank screen problem which generally means a bug has appeared among xrdp and its related packages. I should have kept the old images. I will update whenever I get it working again.
issue reported here and here with Docker v4.16.3. You need to change the RDP port on Windows using the instruction here until the bug is fixed. Other than your Docker or WSL version might be too old. The containers run without problems other than the mentioned bug.
I've verified with a more recent docker host and the issue doesn't exist there.
