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 chipsets

ProMotion 6420

ProMotion 6422

AT24

AT3D

AT25

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 qDeviceq 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 qDeviceq section.

The following driver Options are supported:

Option qHWCursorq qbooleanq

Enable or disable the hardware cursor. Default: on.

Option qNoAccelq qbooleanq

Disable or enable acceleration. Default: acceleration is enabled.

Option qNoLinearq qbooleanq

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

Option qPciRetryq qbooleanq

Enable or disable PCI retries. Default: off.

Option qRemap_DPMS_Onq qstringq

Option qRemap_DPMS_Standbyq qstringq

Option qRemap_DPMS_Suspendq qstringq

Option qRemap_DPMS_Offq qstringq

Remaps the corresponding DPMS events. I've found that my Hercules 128/3D swaps Off and Suspend events. You can correct that with

Option qRemap_DPMS_Suspendq qOffq
Option qRemap_DPMS_Offq qSuspendq

in the Device section of the config file.

Option qSWCursorq qbooleanq

Force the software cursor. Default: off.

Option qShadowFBq qbooleanq

Enable or disable use of the shadow framebuffer layer. Default: off.
