CONFIGURATION DETAILS

The driver auto-detects the chipset type, but the following ChipSet names may optionally be specified in the config file N'34'DeviceN'34' section, and will override the auto-detection:

"mga2064w", "mga1064sg", "mga2164w", "mga2164w agp", "mgag100", "mgag200", "mgag200 pci" "mgag400".

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 N'34'DeviceN'34' section.

The following driver Options are supported:

Option N'34'ColorKeyN'34' N'34'integerN'34'

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 N'34'HWCursorN'34' N'34'booleanN'34'

Enable or disable the HW cursor. Default: on.

Option N'34'MGASDRAMN'34' N'34'booleanN'34'

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 secondary heads in multihead configurations so this option will often need to be specified in multihead configurations. Default: auto-detected.

Option N'34'NoAccelN'34' N'34'booleanN'34'

Disable or enable acceleration. Default: acceleration is enabled.

Option N'34'OverclockMemN'34'

Set clocks to values used by some commercial X-Servers (G100, G200 and G400 only). Default: off.

Option N'34'OverlayN'34'

Enable 8+24 overlay mode. Only appropriate for depth 24. (Note: the G100 is unaccelerated in the 8+24 overlay mode due to a missing hardware feature.) Default: off.

Option N'34'PciRetryN'34' N'34'booleanN'34'

Enable or disable PCI retries. Default: off.

Option N'34'RotateN'34' N'34'CWN'34'

Option N'34'RotateN'34' N'34'CCWN'34'

Rotate the display clockwise or counterclockwise. This mode is unaccelerated. Default: no rotation.

Option N'34'ShadowFBN'34' N'34'booleanN'34'

Enable or disable use of the shadow framebuffer layer. See shadowfb(4) for further information. Default: off.

Option N'34'SyncOnGreenN'34' N'34'booleanN'34'

Enable or disable combining the sync signals with the green signal. Default: off.

Option N'34'UseFBDevN'34' N'34'booleanN'34'

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 N'34'VideoKeyN'34' N'34'integerN'34'

This sets the default pixel value for the YUV video overlay key. Default: undefined.

Option N'34'TexturedVideoN'34' N'34'booleanN'34'

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.
