You're almost there, Sun, and BAP got you home in the msg before this one. Be sure client-type has the hyphen. Hint: I couldn't find the OK or Save buttons until I thought to maximize the windows.
The above takes care of the Step 1 stuff from BAP's original quoted directions, then go back to his msg and pick up after that and do the stuff that I ERRANTLY told you not to do. That stuff dedicates a core to a GPU and takes the core from SMP, thus preventing SMP from being continually halted each time the GPU wants it.
Kapowerrific!
