Docker Desktop does not start and returns no error

Just getting started with Docker.
Docker Engine installed, I can pull images and run instances in containers.
Trying to work with Docker Desktop now.

Host: Ubuntu 18.04
Dell XPS Intel® Core™ i7-8750H CPU @ 2.20GHz × 12

I installed docker-desktop-41.19.0-amd64.deb (I did not see an installer for x86_64) according to the instructions at the Docker site for installing Docker Desktop for Linux.

After installing, the Docker Desktop shows up in my applications, but when I click on it, nothing happens.

When I run from a command line (systemctl --user start docker-desktop), the same thing - I just get my prompt back and no error.

Thanks in advance for looking at this.

amd64 and x86_64 mean the same.

If you are looking for error messages that will probably not come when you start a service on Linux unless it is running in the foreground, but systemctl starts it in the background. systemctl --user status docker-desktop could tell you more about the status of the service.

This is what I get when I use the status command
