matroxset - switch the output mode of Matrox video cards
SYNOPSIS
matroxset [OPTIONS] [VALUE]
OPTIONS -c Get/set control value.
-e Edit controls interactively.
-f DEVICE
Manipulate the frame buffer DEVICE (default is /dev/fb1).
-l List controls
-m Connect this frame buffer to the outputs specified in VALUE (0 is none, 1 is primary, 2 is secondary, 4 is digital flat panel; these
values may be summed for multiple outputs).
-o OUTPUT
Set OUTPUT (0 is primary, 1 is secondary, default is 1) to the output mode VALUE (128 is monitor, 1 is PAL TV, 2 is NTSC TV).
-p Display information about blanking.
DESCRIPTION
Output Matrox card video to television. PAL 50Hz and NTSC 59.94Hz are supported, Composite and S-Video output.
Contains two demo programs, normal and swapped. First selects CRTC1 on first output and CRTC2 on second one. Swapped connects CRTC1 to
secondary head and CRTC2 to primary head. You can use these programs if you need text mode or 8bpp mode on TV, as CRTC2 is incapable of
these modes.
In program call, If VALUE is specified, set the specified option to VALUE. If VALUE is not specified, retrieve the value of the specified
option.

mga - Matrox video driver
SYNOPSIS
Section "Device"
Identifier "devname"
Driver "mga"
...
EndSection
DESCRIPTION
mga is an XFree86 driver for Matrox video cards. The driver is fully accelerated, and provides support for the following framebuffer
depths: 8, 15, 16, 24, and an 8+24 overlay mode. All visual types are supported for depth 8, and both TrueColor and DirectColor visuals
are supported for the other depths except 8+24 mode which supports PseudoColor, GrayScale and TrueColor. Multi-card configurations are
supported. XVideo is supported on G200 and newer systems, with either TexturedVideo or video overlay. The second head of dual-head cards
is supported for the G450 and G550. Support for the second head on G400 cards requires a binary-only "mga_hal" module that is available
from Matrox <http://www.matrox.com>, and may be on the CD supplied with the card. That module also provides various other enhancements,
and may be necessary to use the DVI (digital) output on the G550 (and other cards).
SUPPORTED HARDWARE
The mga driver supports PCI and AGP video cards based on the following Matrox chips:
MGA2064W Millennium (original)
MGA1064SG Mystique
MGA2164W Millennium II
G100
G200 Millennium G200 and Mystique G200
G400
G450
G550
CONFIGURATION DETAILS
Please refer to XF86Config(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:
"mga2064w", "mga1064sg", "mga2164w", "mga2164w agp", "mgag100", "mgag200", "mgag200 pci", "mgag400", "mgag550".
The G450 is Chipset "mgag400" with ChipRev 0x80.
The driver will auto-detect the amount of video memory present for all chips except the Millennium II. In the Millennium II case it
defaults to 4096 kBytes. When using a Millennium II, the actual amount of video memory should be specified with a VideoRam entry in the
config file "Device" section.
The following driver Options are supported:
Option "ColorKey" "integer"
Set the colormap index used for the transparency key for the depth 8 plane when operating in 8+24 overlay mode. The value must be
in the range 2-255. Default: 255.
Option "HWCursor" "boolean"
Enable or disable the HW cursor. Default: on.
Option "MGASDRAM" "boolean"
Specify whether G100, G200 or G400 cards have SDRAM. The driver attempts to auto-detect this based on the card's PCI subsystem ID.
This option may be used to override that auto-detection. The mga driver is not able to auto-detect the presence of of SDRAM on sec-
ondary heads in multihead configurations so this option will often need to be specified in multihead configurations. Default: auto-
detected.
Option "NoAccel" "boolean"
Disable or enable acceleration. Default: acceleration is enabled.
Option "NoHal" "boolean"
Disable or enable loading the "mga_hal" module. Default: the module is loaded when available and when using hardware that it sup-
ports.
Option "OverclockMem"
Set clocks to values used by some commercial X-Servers (G100, G200 and G400 only). Default: off.
Option "Overlay" "value"
Enable 8+24 overlay mode. Only appropriate for depth 24. Recognized values are: "8,24", "24,8". Default: off. (Note: the G100 is
unaccelerated in the 8+24 overlay mode due to a missing hardware feature.)
Option "PciRetry" "boolean"
Enable or disable PCI retries. Default: off.
Option "Rotate" "CW"
Option "Rotate" "CCW"
Rotate the display clockwise or counterclockwise. This mode is unaccelerated. Default: no rotation.
Option "ShadowFB" "boolean"
Enable or disable use of the shadow framebuffer layer. Default: off.
Option "SyncOnGreen" "boolean"
Enable or disable combining the sync signals with the green signal. Default: off.
Option "UseFBDev" "boolean"
Enable or disable use of on OS-specific fb interface (and is not supported on all OSs). See fbdevhw(4) for further information.
Default: off.
Option "VideoKey" "integer"
This sets the default pixel value for the YUV video overlay key. Default: undefined.
Option "TexturedVideo" "boolean"
This has XvImage support use the texture engine rather than the video overlay. This option is only supported by the G200 and G400,
and only in 16 and 32 bits per pixel. Default: off.
