%description
The Extensible Virtual Display Interface (EVDI) is a Linux kernel module that
enables management of multiple screens, allowing user-space programs to take
control over what happens with the image. It is essentially a virtual display
you can add, remove and receive screen updates for, in an application that
uses the libevdi library.

It is needed primarily for DisplayLink driver.
