DESCRIPTION

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.

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 \N’34’Device\N’34’ 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 \N’34’Device\N’34’ section.

The following driver Options are supported:
Option \N’34’HWCursor\N’34’ \N’34’boolean\N’34’
  Enable or disable the hardware cursor. Default: on.
Option \N’34’NoAccel\N’34’ \N’34’boolean\N’34’
  Disable or enable acceleration. Default: acceleration is enabled.
Option \N’34’PciRetry\N’34’ \N’34’boolean\N’34’
  Enable or disable PCI retries. Default: off.
Option \N’34’Remap_DPMS_On\N’34’ \N’34’string\N’34’
Option \N’34’Remap_DPMS_Standby\N’34’ \N’34’string\N’34’
Option \N’34’Remap_DPMS_Suspend\N’34’ \N’34’string\N’34’
Option \N’34’Remap_DPMS_Off\N’34’ \N’34’string\N’34’
  Remaps the corresponding DPMS events. I’ve found that my Hercules 128/3D swaps Off and Suspend events. You can correct that with


  Option \N’34’Remap_DPMS_Suspend\N’34’ \N’34’Off\N’34’ Option \N’34’Remap_DPMS_Off\N’34’ \N’34’Suspend\N’34’
in the Device section of the config file.
Option \N’34’SWCursor\N’34’ \N’34’boolean\N’34’
  Force the software cursor. Default: off.
Option \N’34’ShadowFB\N’34’ \N’34’boolean\N’34’
  Enable or disable use of the shadow framebuffer layer. Default: off.
