The GNU Screen manual tells you that to use scrolling, you must first enter “Copy mode” with C-a [.

You can easily fix this and use regular PgUp/PgDn by simply adding a line to your ~/.screenrc. I really don’t know why this isn’t a default setting except that it seems to mess with Vim scrollback.

Here’s the line:

termcapinfo xterm ti@:te@

Enjoy.
