TechDave1969; Let me convey to you the correct answer and product(s) to use to achieve a great finish. Is this just another incorrect or unqualified answer? Review who I am, here and/or through an internet search, and the go to my website to decide that for yourself.
What happens with new drywall that plagues most people is that they don immediately realize that the paper and the mud absorb the primer differently, thus you won get the wall effectively blocked out either one coat of PVA, or conventional drywall primers. What going to happen as a result of this is you be painting and panting and painting. . . and still get what known as flash and not the finish you envisioned.
So what to do? You use "USG First Coat" primer/sealer, or go to Lowe and get their "Construction First Step" primer/sealer, using that instead of the others. These are essentially high build primers that WILL provide you adequate coverage in one good coat and eliminate what killing you. Also, contrary to what I read posted to this question, yes you do sand in between coats of the primers I've described above if you looking for a level 5 finish, which is truly smooth wall. Sanding flattens and removes any trash that was caught up in your roller cover, or kicked up by your sprayer and effectively promotes a truly smooth wall finish.
Have the primer tinted a light grey as it will eliminate you being white blinded and shadowed and allow you to proof/punch out any minor imperfections that you will miss using a straight white primer. The grey, being truly neutral, will provide a great base color to apply bright (whites) or deep tone colors over. . . trust me, I know my stuff.
Now if you decided to followed my advice, finding it competent, let me take you another step or two. Use a 1.25" or 1.5" lambs wool roller cover (what we call a wooly) when priming; it put the product on the walls ceilings and 9 out of 10 times do it in one coat. Back roll "all" applications of primer and paint to avoid trails, get even coverage, and eliminate flash that often results in eggshell and semi-gloss sheens. I actually use the same size roller covers with primer as I do with paint, and if you follow my advice on this and the above, you have beautiful surfaces with a fine paint stipple,
