There may be a quit context menu item. This is how some programs like Amarok and Ktorrent work as well. If you were downloading the latest disto's dvd via a torrent, you would close the main display after starting the download. The program will continue to operate in the background with an icon displayed in the tray. The program that you call may be a wrapper that calls another program and then quits.

I'm not sure where the localhost display is coming from but it is also related to the SSH forwarding. Did you do just one SSH hop, or two? You may have more success, if you enable TCP listening directly on your workstation X server remove '-nolisten tcp' flags and you might need to add '-listen tcp' then tell the docker container to use your workstation display directly.

I have an old sample docker container somewhere on gitbub that does this for running Azureus I'll see if I can find the link. Sometimes it is a lot easier to add a VNC server into the container, start your Java app within a vnc session in the container, and use vnc to connect to it from the workstation. That gets around needing to add VNC packages into your container. Sign up to join this community.

Ask Ubuntu is a question and answer site for Ubuntu users and developers. It only takes a minute to sign up. I am new to shell scripting. What does this mean? A display is managed by a server program, known as an X server. The server serves displaying capabilities to other programs that connect to it. The remote server knows where it have to redirect the X network traffic via the definition of the DISPLAY environment variable which generally points to an X Display server located on your local computer.

An omitted hostname means the localhost. D is a sequence number usually 0. It can be varied if there are multiple displays connected to one computer.

S is the screen number. A display can actually have multiple screens. Usually there's only one screen though where 0 is the default. Read more here and here and here. This information is used by the application to determine how it should connect to the server and which screen it should use by default on displays with multiple monitors :.

If the hostname is not given, the most efficient way of communicating to a server on the same machine will be used. Most workstations tend to only have one keyboard, and therefore, only one display.

Larger, multi-user systems, however, frequently have several displays so that more than one person can be doing graphics work at once. To avoid confusion, each display on a machine is assigned a display number beginning at 0 when the X server for that display is started. The display number must always be given in a display name.
