You have to display the centroids to be able to see labels, i.e.

d.vect census_wake2000 display=shape,cat type=point,line,boundary,area,face

will not display the cat values, while

d.vect census_wake2000 display=shape,cat 
type=point,line,boundary,area,face,centroid

will.

No need to use attr if all you want to see are the categories of the 
features (unless your attribute table's cat column does not correspond 
to the category values of the features, but represents a separate 
attribute, then attr is needed, but cat not.)
