       r128 - ATI Rage 128 video driver

       Section "Device"
	 Identifier "devname"
	 Driver "r128"

       r128 is an Xorg driver for ATI Rage 128 based video cards.  It contains
       full support for 8, 15, 16 and 24 bit pixel depths, hardware  accelera‐
       tion  of	 drawing  primitives,  hardware	 cursor,  video	 modes	up  to
       1800x1440 @ 70Hz, doublescan modes (e.g., 320x200 and  320x240),	 gamma
       correction  at  all  pixel  depths,  a  fully programming dot clock and
       robust text mode restoration for VT switching.  Dualhead	 is  supported
       on M3/M4 mobile chips.

       The  r128  driver supports all ATI Rage 128 based video cards including
       the Rage Fury AGP 32MB, the XPERT 128 AGP 16MB and  the	XPERT  99  AGP

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

       The driver auto-detects all device information necessary to  initialize
       the  card.   However, if you have problems with auto-detection, you can

	   VideoRam - in kilobytes
	   MemBase  - physical address of the linear framebuffer
	   IOBase   - physical address of the MMIO registers
	   ChipID   - PCI DEVICE ID

       In addition, the following driver Options are supported:

       Option "SWcursor" "boolean"
	      Selects software cursor.	The default is off.

       Option "NoAccel" "boolean"
	      Enables or disables all hardware acceleration.  The  default  is
	      to enable hardware acceleration.

       Option "EnablePageFlip" "boolean"
	      Enable  page  flipping  for  3D acceleration. This will increase
	      performance but not work correctly in some rare cases, hence the
	      default is off.

       Option "RenderAccel" "boolean"
	      Enables  or  disables  hardware Render acceleration.  It is only
	      supported when using EXA acceleration and DRI.  The  default  is
	      to enable Render acceleration.

       Option "AccelMethod" "string"
	      Chooses  between	available  acceleration	 architectures.	 Valid
	      options are XAA and EXA.	XAA is	the  traditional  acceleration
	      architecture  and support for it is very stable.	EXA is a newer
	      acceleration architecture with better performance for the Render
	      and Composite extensions.	 The default is XAA.

       Option "Dac6Bit" "boolean"
	      Enables  or  disables the use of 6 bits per color component when
	      in 8 bpp mode (emulates VGA mode).  By default, all 8  bits  per
	      color component are used.	 The default is off.

       Option "VideoKey" "integer"
	      This overrides the default pixel value for the YUV video overlay
	      key.  The default value is undefined.

       Option "Display" "string"
	      Select display mode for devices which support flat panels.  Sup‐
	      ported modes are:

	      "FP" - use flat panel;

	      "CRT" - use cathode ray tube;

	      "Mirror" - use both FP and CRT;

	      "BIOS" - use mode as configured in the BIOS.

	      The default is FP.

       The following Options are mostly important for non-x86 architectures:

       Option "ProgramFPRegs" "boolean"
	      Enable  or  disable  programming	of  the	 flat panel registers.
	      Beware that this may damage your panel, so use this at your  own
	      risk.  The default depends on the device.

       Option "PanelWidth" "integer"

       Option "PanelHeight" "integer"
	      Override	the  flat panel dimensions in pixels. They are used to
	      program the flat panel registers and normally  determined	 using
	      the  video card BIOS. If the wrong dimensions are used, the sys‐
	      tem may hang.

       Option "UseFBDev" "boolean"
	      Enable or disable	 use  of  an  OS-specific  framebuffer	device
	      interface	 (which	 is not supported on all OSs).	See fbdevhw(4)
	      for further information.	Default: on for PowerPC, off for other

       Option "DMAForXv" "boolean"
	      Try  or  don't  try to use DMA for Xv image transfers. This will
	      reduce CPU usage when playing big	 videos	 like  DVDs,  but  may
	      cause instabilities.  Default: off.

       The following additional Options are supported:

       Option "ShowCache" "boolean"
	      Enable or disable viewing offscreen cache memory.	 A development
	      debug option.  Default: off.

       Option "VGAAccess" "boolean"
	      Tell the driver if it can do legacy VGA IOs to the card. This is
	      necessary	 for properly resuming consoles when in VGA text mode,
	      but shouldn't be if the console is using radeonfb or some	 other
	      graphic  mode  driver.  Some  platforms like PowerPC have issues
	      with those, and they aren't necessary unless  you	 have  a  real
	      text  mode  in  console. The default is off on PowerPC and SPARC
	      and on on other architectures.

       Dualhead Note: The video BIOS on some laptops interacts strangely  with
       dualhead.  This can result in flickering and problems changing modes on
       crtc2.  If you experience these problems	 try  toggling	your  laptop's
       video  output  switch (e.g., fn-f7, etc.) prior to starting X or switch
       to another VT and back.
