Any code called from the driver ScreenInit may want to refer to pScrn->pScreen. As the function passed to AddScreen is the first place the DDX sees a new screen, the generic code needs to make sure that value is set before passing control to the video driver's initialization code. This was found by running a driver which didn't bother to set this value when the initial colormap was installed; xf86RandR12LoadPalette tried to use pScrn->pScreen and crashed.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
