(II) Loading sub module "mga_hal"
(II) LoadModule: "mga_hal"
(WW) Warning, couldn't open module mga_hal
(II) UnloadModule: "mga_hal"
(EE) MGA: Failed to load module "mga_hal" (module does not exist, 0)
(II) MGA(0): Matrox HAL module not loaded - using builtin mode setup instead
The mga_hal submodule is a binary file mga_hal_drv.o which isn't part of
XFree86, but is provided by Matrox.
I find that using it gives better results with the DVI output on my G550.
There is a version of this file on the CD that came with my G550, at
Linux/drivers/xfree86/4.1.0/drivers/mga_hal_drv.o
but I use a version intended for XFree86 version 4.2.0 that came with the
Matrox Linux drivers on their web site. You may find that the CD with a
newer card has the 4.2.0 version on it.
XFree86 built from our sources will use the binary mga_hal_drv.o,
but I've found that the version shipped with Red Hat 8.0 does not
use this module even if it is available.
