problem activiting second screen for Matrox G450 dual-head PCI card

[陈士成]

After looked into Matrox support forum (actually this question should go to
that forum perhaps, though I am not sure if I am on-topic by sending to this
list) a Matrox support stuff said the user should use the driver they
released if dual-head feature is needed. He/she was talking about G450 MMS
("You need to use the matrox beta driver to make an MMS card work."), but I
got no way to tell if I have a MMS card, at leat this is not written on the
card.

Matrox didn't release a driver for Xorg 6.9.0, trying the driver for
6.8.2(latest) gives a lot of Unresolved symbol error. There is an i810
onbard
card but never activated in the BIOS so I guess that is not causing this
problem.
