tigervnc-xorg-extension 1.12.0+dfsg-5 (ppc64el binary) in ubuntu kinetic

 VNC stands for Virtual Network Computing. It is, in essence, a remote display
 system that allows you to view a computing `desktop' environment not only on
 the machine where it is running but from anywhere on the Internet and from a
 wide variety of machine architectures. For this purpose, it implements a
 client/server model.
 .
 This package contains an X server connector so VNC clients can connect to your
 local X desktop directly.
