Michel Dänzer 1c3e51daba xfree86/modes: Bail from xf86RotateRedisplay if pScreen->root is NULL 
Avoids a crash in xf86RotatePrepare -> DamageRegister during
CreateScreenResources if rotation or another transform is configured for
any connected RandR output in xorg.conf. The generic rotation/transform
code generally can't work without the root window currently.

Closes: https://gitlab.freedesktop.org/xorg/xserver/issues/969
Fixes: 094f42cdfe "xfree86/modes: Call xf86RotateRedisplay from
                     xf86CrtcRotate"

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.

For a comprehensive overview of X Server and X Window System, consult the following article: https://en.wikipedia.org/wiki/X_server

All questions regarding this software should be directed at the Xorg mailing list:
