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(5x) 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  dif-
	      ferent depth.

NAME

       fbdev - video driver for framebuffer device

SYNOPSIS

       Section "Device"
	 Identifier "devname"
	 Driver "fbdev"
	 BusID	"pci:bus:dev:func"
	 ...
       EndSection

DESCRIPTION

       fbdev  is  an XFree86 driver for framebuffer devices.  This is a non-accelerated driver, the following framebuffer depths are supported: 8,
       15, 16, 24.  All visual types are supported for depth 8, and TrueColor visual is supported for the other depths.  Multi-head configurations
       are supported.

SUPPORTED HARDWARE

       The fbdev driver supports all hardware where a framebuffer driver is available.	fbdev uses the os-specific submodule fbdevhw(4) to talk to
       the kernel device driver.  Currently a fbdevhw module is available for linux.

CONFIGURATION DETAILS

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

       For this driver it is not required to specify modes in the screen section of the config file.  The fbdev driver can pick up  the  currently
       used video mode from the framebuffer driver and will use it if there are no video modes configured.

       For  PCI  boards you might have to add a BusID line to the Device section.  See above for a sample line.  You can use "XFree86 -scanpci" to
       figure out the correct values.

       The following driver Options are supported:

       Option "fbdev" "string"
	      The framebuffer device to use. Default: /dev/fb0.

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

       Option "Rotate" "string"
	      Enable rotation of the display. The supported values are "CW" (clockwise, 90 degrees), "UD" (upside down,  180  degrees)	and  "CCW"
	      (counter clockwise, 270 degrees). Implies use of the shadow framebuffer layer.   Default: off.
