tigervnc-xorg-extension 1.9.0+dfsg-2 (amd64 binary) in ubuntu disco

 VNC stands for Virtual Network Computing. It is, in essence, a remote
 display system which 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.
 .
 This package contains an X server connector so VNC clients can connect to your
 local X desktop directly.
