     That did it !  Thanks.  Removed it from /etc/default/grub and 
rebuilt grub.cfg.
     But now I have lockup problems on the desktop and to some extent at 
the CLI. I have disabled composting
in Marco ( I'm running the Mate desktop) and nothing else I could see 
that might affect video is on. It's real tight
lockups...nothing works except the power button.
