Should I try all the amd64 packages, i.e. headers, images, and modules 
in both generic and low latency flavors, or is there a specific package? 
I've pulled down the entire amd64 set, and the headers-all as well.

Title:
  [nouveau] screen background overlaid with scan type artifact in red

Status in linux package in Ubuntu:
  Incomplete
Status in mesa package in Ubuntu:
  Incomplete

Bug description:
  My desktop has both it's usual items in place; toolbar on left and
  desktop icons distributed around the screen. Then there's what appears
  to be a bunch of scan line, raster line artifacts, in red, laid over
  my normal background, which is a star field photo on what is
  ordinarily a black field.
