Summary
This document contains a 2-minute walkthrough to get your
Ubuntu 6.06 system with a Matrox G450/G550 card to work with a dualhead
setup.
The Problem
Matrox is a rather old-fashioned corporation, persisting in not
releasing the specs of (obsolete) videocards, and only offering support in
the form of binary-only drivers with some glue. In other words: the
Linux-driver Matrox offers to its clients only supports rather ancient
versions of X. Ubuntu 6.06 LTS contains a fresh version of X.org. So the
problem boils down to convincing the old Matrox driver to work with the new
X.org...
The Solution
- mga_hal.o
- This is the same file as
matrox_driver-x86-4.3.0/xserver/6.8.2/mga_hal_drv.o from the Matrox driver package
which can be found online at Matrox
- mga_drv.so
- This is the driver produced using the procedure outlined in the Matrox
Support Forum
- xorg.conf
- For your convenience, here's a working xorg.conf. Note that a lot of
stuff is defined twice, once for screen 0 and once for screen 1. Also you'll
want to enable Xinerama, or your setup is less than optimal.
After you've downloaded these files, copy the drivers to
/usr/lib/xorg/modules/drivers/, rub your configuration 'til it
bleeds (using the xorg.conf provided here), and then go get some work
done... Good luck!
