VGA(4)                 FreeBSD Kernel Interfaces Manual                 VGA(4)

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
       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 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
              hardware.  It is required when using those depths in a multi-
              head configuration where one or more of the other screens is
              operating at a different depth.
