NAME

       apm - Alliance ProMotion video driver


SYNOPSIS

DESCRIPTION

       apm is an XFree86 driver for Alliance ProMotion video cards. The driver
       is accelerated for supported hardware/depth  combination.  It  supports
       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(5) 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 "SWCursor" "boolean"
              Force the software cursor.  Default: off.

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