Travis:

  I ran your code on REDHAT 6.2 using svga ver 1.4.1
  and it runs OK.

  The error is not coming from eu_engin.e but from svga lib
  It maybe your svga settings in libvga.config or your video card
  is not supported by svga lib. Maybe you should read the svga
  lib docs about that message

  about resetting the driver.

  Like Mike said try running different modes.
