[PlanetCCRMA] soundcard must be detected via local display before detected via vnc IT WORKS

[Bengt Månsson]

Hi
I use Fedora 8 (I couldn't install 7, it did'nt find drivers for my dvd or
something. a known bug they don't care to fix)
I copied your suggestions into the file and restarted.
Thanks a lot Fernando, it works!
(now the crt goes back to the attic)
