NAME
       apm - Alliance ProMotion video driver

SYNOPSIS

         Driver "apm"

       EndSection

DESCRIPTION
       apm is an Xorg driver for Alliance ProMotion video cards. The driver is accelerated for supported hardware/depth combina-
       tion. 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 xorg.conf(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 "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.
