DESCRIPTION

16       apm is an Xorg driver for Alliance ProMotion video cards. The driver is
17       accelerated  for  supported  hardware/depth  combination.  It  supports
18       framebuffer  depths of 8, 15, 16, 24 and 32 bits. For 6420, 6422, AT24,
19       AT3D and AT25, all depths are fully accelerated except 24 bpp for which
20       only screen to screen copy and rectangle filling is accelerated.
21

SUPPORTED HARDWARE

23       The  apm  driver  supports  PCI  and  ISA  video cards on the following
24       Alliance ProMotion chipsets
25
26       ProMotion 6420
27
28       ProMotion 6422
29
30       AT24
31
32       AT3D
33
34       AT25
35

CONFIGURATION DETAILS

37       Please refer to xorg.conf(5) for general configuration  details.   This
38       section only covers configuration details specific to this driver.
39
40       The  driver  auto-detects  the  chipset type, but the following ChipSet
41       names may optionally be specified in the config file "Device"  section,
42       and will override the auto-detection:
43
44           "6422", "at24", "at3d".
45
46           The AT25 is Chipset "at3d" and the 6420 is 6422.
47
48           The  driver will auto-detect the amount of video memory present for
49           all chips. The actual amount of video memory can also be  specified
50           with a VideoRam entry in the config file "Device" section.
51
52           The following driver Options are supported:
53
54           Option "HWCursor" "boolean"
55                  Enable or disable the hardware cursor.  Default: on.
56
57           Option "NoAccel" "boolean"
58                  Disable  or  enable  acceleration.  Default: acceleration is
59                  enabled.
60
61           Option "NoLinear" "boolean"
62                  Disable or enable use of linear frame buffer.  Default:  on.
63                  Note: it may or may not work. Tell me if you need it.
64
65           Option "PciRetry" "boolean"
66                  Enable or disable PCI retries.  Default: off.
67
68           Option "Remap_DPMS_On" "string"
69
70           Option "Remap_DPMS_Standby" "string"
71
72           Option "Remap_DPMS_Suspend" "string"
73
74           Option "Remap_DPMS_Off" "string"
75                  Remaps  the  corresponding  DPMS  events. I've found that my
76                  Hercules 128/3D swaps Off and Suspend events. You  can  cor‐
77                  rect that with
78                         Option "Remap_DPMS_Suspend" "Off"
79                         Option "Remap_DPMS_Off" "Suspend"
80                  in the Device section of the config file.
81
82                  Option "SWCursor" "boolean"
83                         Force the software cursor.  Default: off.
84
85                  Option "ShadowFB" "boolean"
86                         Enable  or  disable  use  of  the  shadow framebuffer
87                         layer.  Default: off.
