NAME

       i810 - Intel 8xx integrated graphics chipsets

SYNOPSIS

       Section "Device"
	 Identifier "devname"
	 Driver "i810"
	 ...
       EndSection

DESCRIPTION

       i810  is an XFree86 driver for Intel integrated graphics chipsets.  The driver supports depths 8, 15, 16 and 24.  All visual types are sup-
       ported in depth 8, other depths only support TrueColor.	The driver supports hardware accelerated 3D via the Direct  Rendering  Infrastruc-
       ture (DRI), but only in depth 16 for the i810/i815 and depths 16 and 24 for later chipsets.

SUPPORTED HARDWARE

       i810 supports the i810, i810-DC100, i810e, i815, 830M, 845G, 852GM, 855GM, and 865G chipsets.

CONFIGURATION DETAILS

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

       The  Intel 8xx family of integrated graphics chipsets has a unified memory architecture and uses system memory for video ram.  By default 8
       Megabytes of system memory are used for graphics.  For the 830M and later, the default is 8 Megabytes  when  DRI  is  not  enabled  and	32
       Megabytes with DRI is enabled.  This amount may be changed with the VideoRam entry in the config file Device section.  It may be set to any
       reasonable value up to 64MB for older chipsets or 128MB for newer chipets.  Note that increasing this value will reduce the amount of  sys-
       tem memory available for other applications.

       The following driver Options are supported

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

       Option "SWCursor" "boolean"
	      Disable or enable software cursor.  Default: software cursor is disable and a hardware cursor is used.

       Option "ColorKey" "integer"
	      This sets the default pixel value for the YUV video overlay key.	Default: undefined.

       Option "CacheLines" "integer"
	      This allows the user to change the amount of graphics memory used for 2D acceleration and video.	Decreasing this amount leaves more
	      for 3D textures.	Increasing it can improve 2D performance at the expense of 3D performance.  Default: 256 to 768 depending  on  the
	      resolution and depth.

NAME

       neomagic - Neomagic video driver

SYNOPSIS

       Section "Device"
	 Identifier "devname"
	 Driver "neomagic"
	 ...
       EndSection

DESCRIPTION

       neomagic is an Xorg driver for the Neomagic graphics chipsets found in many laptop computers.

SUPPORTED HARDWARE

       neomagic supports the following chipsets:

       MagicGraph 128	 (NM2070)

       MagicGraph 128V	 (NM2090)

       MagicGraph 128ZV  (NM2093)

       MagicGraph 128ZV+ (NM2097)

       MagicGraph 128XD  (NM2160)

       MagicGraph 256AV  (NM2200)

       MagicGraph 256AV+ (NM2230)

       MagicGraph 256ZX  (NM2360)

       MagicGraph 256XL+ (NM2380)

       The driver supports depths 8, 15, 16 and 24 for all chipsets except the NM2070 which does not support depth 24.	All depths are accelerated
       except for depth 24 which is only accelerated on NM2200 and newer models.  All visuals are supported in depth 8.  TrueColor and DirectColor
       visuals are supported in the other depths.

CONFIGURATION DETAILS

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

       The following driver Options are supported

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

       Option "SWCursor" "boolean"
	      Disable or enable software cursor.  Default: software cursor is disable and a hardware cursor is used.

       Option "PCIBurst" "boolean"
	      Disable or enable PCI burst modes.  Default: enabled.

       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 "OverlayMem" "integer"
	      Reserve  the  given amount of memory (in bytes) for the XVideo overlay.  On boards with limited memory, display of large XVideo buf-
	      fers might fail due to insufficient available memory.  Using this option solves the problem at the expense of  reducing  the  memory
	      available for other operations.  For full-resolution DVDs, 829440 bytes (720x576x2) are necessary.

       Note
       On some laptops using the 2160 chipset (MagicGraph 128XD) the following options are needed to avoid a lock-up of the graphic engine:
	   Option "XaaNoScanlineImageWriteRect"
	   Option "XaaNoScanlineCPUToScreenColorExpandFill"
