Dear all,

I have an odd Xorg error with a Matrox G200 card here. I have googled for it but only found dual-head installations, plus comments that it allegedly is fixed with the new FreeBSD Xorg 1.5.3 ports.

However, as I still see the error, I poked about and could not find much of the changes people had suggested in the driver as unpacked from current ports. But since XFree, Xorg and the various releases are a complete miracle to me, my evaluation may just be plain wrong.

So, if there was anyone knowing how to possibly fix the matter, I'd appreciate a hint (or two or so ;-)).

All the best,

Peter.
