Hi all,

I'm trying setup xinerama on my computer, that has one Matrox MGA G200 AGP
videl card with 4 outputs. Two monitors are connected to 2 of 4 outputs. My
computer runs NetBSD-2.0. Here is my prolem. When I run startx, I can the the
half of X-Windows on the first monitor. On the second one, I can see only
black and white lines, no window at all. Could anyone explain me what problem
is and how to get it fixed. I've tried to add 3 lines "vga* at pci? dev ?
function ?" to GENERIC file and rebuild the kernel with the hope that the
kernel would recognize the second monitor. But I got the same results. Could
anyone explain me how the kernel and xserver are related. If the kernel can't
initialize a drive, can the xserver recognize and accesses the hardware (pci)
by itself. Any suggestion and comment on the above problem is highly
appreciated. I attached here my XF86Config, dmesg.boot and MYKERNEL files for
your reference.
Thank you very much
