NAME
       mga - Matrox video driver

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

DESCRIPTION
       mga  is	an  XFree86  driver for Matrox video cards.  The driver is fully accelerated, and
       provides support for the following framebuffer depths: 8, 15, 16, 24, and an 8+24  overlay
       mode.   All  visual  types  are	supported for depth 8, and both TrueColor and DirectColor
       visuals are supported for the other depths except 8+24 mode  which  supports  PseudoColor,
       GrayScale and TrueColor.  Multi-card configurations are supported.  XVideo is supported on
       G200 and newer systems, with either TexturedVideo or video overlay.  The  second  head  of
       dual-head  cards  is supported for the G450 and G550.  Support for the second head on G400
       cards  requires	a  binary-only	"mga_hal"  module   that   is	available   from   Matrox
       <http://www.matrox.com>,  and  may  be on the CD supplied with the card.  That module also
       provides various other enhancements, and may be necessary to use the DVI (digital)  output
       on the G550 (and other cards).

SUPPORTED HARDWARE
       The mga driver supports PCI and AGP video cards based on the following Matrox chips:

       MGA2064W    Millennium (original)

       MGA1064SG   Mystique

       MGA2164W    Millennium II

       G100

       G200	   Millennium G200 and Mystique G200

       G400

       G450

       G550

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

       The driver auto-detects the chipset type, but the following ChipSet names  may  optionally
       be specified in the config file "Device" section, and will override the auto-detection:

	   "mga2064w",	"mga1064sg",  "mga2164w",  "mga2164w agp", "mgag100", "mgag200", "mgag200
	   pci", "mgag400", "mgag550".

       The G450 is Chipset "mgag400" with ChipRev 0x80.

       The driver will auto-detect the amount of video memory present for all  chips  except  the
       Millennium  II.	 In the Millennium II case it defaults to 4096 kBytes.	When using a Mil-
       lennium II, the actual amount of video memory should be specified with a VideoRam entry in
       the config file "Device" section.

       The following driver Options are supported:

       Option "ColorKey" "integer"
	      Set  the	colormap  index  used for the transparency key for the depth 8 plane when
	      operating in 8+24 overlay mode.  The value must be in the  range	2-255.	 Default:
	      255.

       Option "HWCursor" "boolean"
	      Enable or disable the HW cursor.	Default: on.

       Option "MGASDRAM" "boolean"
	      Specify  whether G100, G200 or G400 cards have SDRAM.  The driver attempts to auto-
	      detect this based on the card's PCI subsystem ID.  This option may be used to over-
	      ride  that  auto-detection.  The mga driver is not able to auto-detect the presence
	      of of SDRAM on secondary heads in multihead  configurations  so  this  option  will
	      often need to be specified in multihead configurations.  Default: auto-detected.

       Option "NoAccel" "boolean"
	      Disable or enable acceleration.  Default: acceleration is enabled.

       Option "NoHal" "boolean"
	      Disable or enable loading the "mga_hal" module.  Default: the module is loaded when
	      available and when using hardware that it supports.

       Option "OverclockMem"
	      Set clocks to values used by some commercial X-Servers (G100, G200 and G400  only).
	      Default: off.

       Option "Overlay"
	      Enable 8+24 overlay mode.  Only appropriate for depth 24.  (Note: the G100 is unac-
	      celerated in the 8+24 overlay mode due to a  missing  hardware  feature.)  Default:
	      off.

       Option "PciRetry" "boolean"
	      Enable or disable PCI retries.  Default: off.

       Option "Rotate" "CW"

       Option "Rotate" "CCW"
	      Rotate  the  display  clockwise  or  counterclockwise.  This mode is unaccelerated.
	      Default: no rotation.

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

       Option "SyncOnGreen" "boolean"
	      Enable or disable combining the sync signals with the green signal.  Default: off.

       Option "UseFBDev" "boolean"
	      Enable or disable use of on OS-specific fb interface (and is not supported  on  all
	      OSs).  See fbdevhw(4x) for further information.  Default: off.

       Option "VideoKey" "integer"
	      This  sets  the  default pixel value for the YUV video overlay key.  Default: unde-
	      fined.

       Option "TexturedVideo" "boolean"
	      This has XvImage support use the texture engine  rather  than  the  video  overlay.
	      This  option is only supported by the G200 and G400, and only in 16 and 32 bits per
	      pixel.  Default: off.
