NAME
       vga - Generic VGA video driver

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

DESCRIPTION
       vga  is	an Xorg	driver for generic VGA video cards.  It	can drive most
       VGA-compatible video cards, but only makes use of  the  basic  standard
       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 xorg.conf(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.
