[X2Go-User] X-Video extension missing

[Ingo Brückl]

On a client notebook with integrated Intel UHD-Grafik 605 running Windows 10
a video player complains that "it seems there is no Xvideo support for your
video card available".

And, indeed, xvinfo reports on the client:

  $ xvinfo
  X-Video Extension version 2.2
  screen #0
   no adaptors present

So, is it VcXsrv which lacks the support or any of the X libraries? Is there
anything that can be done about it, like loading a module or such?
