xnest 2:1.19.6-1ubuntu4.1 (s390x binary) in ubuntu bionic

 Xnest is a nested X server that simply relays all its requests to another
 X server, where it runs as a client. This means that it appears as another
 window in your current X session. Xnest relies upon its parent X server
 for font services.
 .
 Use of the Xephyr X server instead of Xnest is recommended.
 .
