The VGA arbiter controls the PCI bus' routing of legacy VGA resources, specifically the video memory aperture at 0xa0000-0xb0000 (640k should be etc.) and a handful of I/O ports. Since 128k is far too small for a real framebuffer these days, every driver instead maps a linear version of VRAM through the PCI BAR. And no DRI2 drivers ever need I/O port access, because all operations they might be used for (legacy VGA CRTC setup, mostly) happen on the kernel side. In other words, this just works, and we can stop breaking it. Signed-off-by: Adam Jackson <ajax@redhat.com> Reviewed-by: Dave Airlie <airlied@redhat.com> |

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
