Install Atom as a snap

Atom has long been our favourite editor.
Normal installation method now is using Snap

$ snap install atom --classic

Need to override confinement as the editor will make changes outside of the normal sandbox snaps run in.

Whether you use te snap or traditional installation method you may find that the Atom display does not appear.

There are many possible causes (e.g. wide or multi monitors) but for us the cause was very specifc.
We use X2Go to connect from Windows to our XUbuntu desktop.
For Atom a specific change in the X2Go configuration is needed for the display to appear.
Add the following to /etc/x2go/x2goagent.options and restart the X2Go session.
