for those die-hard Matrox users out there (my card is a G550):
To use mga_hal with the new X server, unpack
matrox_driver-x86_32-4.4.0.tar.gz (or matrox_driver-x86_64-4.4.0.tar.gz,
in case of amd64) (do "make extract" in x11-servers/mga_hal) and
copy matrox_driver-x86_32-4.4.0/xserver/7.0.0/mga_{hal_,}drv.so to
/usr/local/lib/xorg/modules/drivers (don't forget to back up mga_drv.so).
>From now on, start your X server with "-ignoreABI", e.g. xdm users
edit /usr/local/lib/X11/xdm/Xservers nd add the mentioned option to
the X server command line.
Without mga_hal, I do not get any signal to my monitor via DVI,
but now fvwm is up and running.
Thanks to the "Unofficial Matrox Support Forum" hosted at
If this is not considered a "trivial fix", I will write a PR
