NAME
       vga - Generic VGA video driver

SYNOPSIS
       Section "Device"
	 Identifier "devname"
	 Driver	"vga"
	 ...
       EndSection

DESCRIPTION
       vga  is	an  XFree86  driver for	generic	VGA video cards.  It can drive
       most VGA-compatible video cards,	but only makes use of the basic	 stan-
       dard  VGA  core	that  is  common  to these cards.  The driver supports
       depths 1, 4 and 8.  All relevant	visual types  are  supported  at  each
       depth.	Multi-head  configurations  are	 supported in combination with
       some other drivers, but only when the vga driver	is driving the primary
       head.

SUPPORTED HARDWARE
       The  vga	 driver	 supports  most	VGA-compatible video cards.  There are
       some known exceptions, and those	should be listed here.

CONFIGURATION DETAILS
       Please refer to XF86Config(5) for general configuration details.	  This
       section only covers configuration details specific to this driver.

       The  driver  auto-detects the presence of VGA-compatible	hardware.  The
       ChipSet name may	optionally be specified	in the	config	file  "Device"
       section,	and will override the auto-detection:

	   "generic"

       The  driver  will  only use 64k of video	memory for depth 1 and depth 8
       operation, and 256k of video memory for depth 4 (this is	 the  standard
       VGA limit).

       When operating at depth 8, only a single	built-in 320x200 video mode is
       available.  At other depths there is more  flexibility  regarding  mode
       choice.

       The following driver Options are	supported:

       Option "ShadowFB" "boolean"
	      Enable or	disable	use of the shadow framebuffer layer.  Default:
	      off.

	      This option is recommended for performance reasons when  running
	      at  depths 1 and 4, especially when using	modern PCI-based hard-
	      ware.  It	is required when using those depths  in	 a  multi-head
	      configuration  where one or more of the other screens is operat-
	      ing at a different depth.
