NAME

       vga - Generic VGA video driver

SYNOPSIS

	 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

       apm - Alliance ProMotion video driver

SYNOPSIS

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

DESCRIPTION

       apm  is	an  XFree86 driver for Alliance ProMotion video cards. The driver is accelerated for supported hardware/depth combination. It sup-
       ports framebuffer depths of 8, 15, 16, 24 and 32 bits. For 6420, 6422, AT24, AT3D and AT25, all depths are fully accelerated except 24  bpp
       for which only screen to screen copy and rectangle filling is accelerated.

SUPPORTED HARDWARE

       The apm driver supports PCI and ISA video cards on the following Alliance ProMotion chipsets

       ProMotion 6420

       ProMotion 6422

       AT24

       AT3D

       AT25

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

	   "6422", "at24", "at3d".

	   The AT25 is Chipset "at3d" and the 6420 is 6422.

	   The driver will auto-detect the amount of video memory present for all chips. The actual amount of video memory can also  be  specified
	   with a VideoRam entry in the config file "Device" section.

	   The following driver Options are supported:

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

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

	   Option "NoLinear" "boolean"
		  Disable or enable use of linear frame buffer. Default: on.  Note: it may or may not work. Tell me if you need it.

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

	   Option "Remap_DPMS_On" "string"

	   Option "Remap_DPMS_Standby" "string"

	   Option "Remap_DPMS_Suspend" "string"

	   Option "Remap_DPMS_Off" "string"
		  Remaps the corresponding DPMS events. I've found that my Hercules 128/3D swaps Off and Suspend events. You can correct that with
			 Option "Remap_DPMS_Suspend" "Off"
			 Option "Remap_DPMS_Off" "Suspend"
		  in the Device section of the config file.

		  Option "SWCursor" "boolean"
			 Force the software cursor.  Default: off.

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