--- Comment #2 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Are you using a compositor? Are you using kwin?

In order for prime to work, you must use a compositor. There are also reports
of kwin occasionally ending up with black windows, which you can fix by
minimizing and restoring the window. (Although that's not the issue in the
screenshot.)
