       apm - Alliance ProMotion video driver


       Section "Device"
         Identifier "devname"
         Driver "apm"


       apm  is  an  Xorg 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.


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

       ProMotion 6420

       ProMotion 6422





       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.
