Dual head howto?
Hi,
I have a 16 MB dual-head Matrox G400 and a spare 15" monitor, currently
running X at 1152x864 w/24 bit depth on my main 17" display. I'm having
trouble finding documentation for configuring the second head.
I'm running Blackbox on Debian GNU/Linux with a custom kernel to support
the Matrox frame buffer, XFree86 Version 4.1.0.1 / X Window System. The
XF86Config-4 man page has some good examples for setting up multiple
"Monitor" and "Screen" sections, but I'm confused about how to tell it
to put the 17" Monitor on the primary head and the 15" Monitor on the
second head.
Pointers to the right docs and/or specific configuration examples
appreciated. Here's the output from dmesg, which seems to indicate that
the second screen buffer is being allocated.
