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. matroxfb: Matrox G400 (AGP) detected matroxfb: MTRR's turned on matroxfb: 1024x768x8bpp (virtual: 1024x16380) matroxfb: framebuffer at 0xD8000000, mapped to 0xce81f000, size 16777216 Console: switching to colour frame buffer device 128x48 fb0: MATROX VGA frame buffer device . . . i2c-core.o: adapter DDC:fb0 #0 on i2c-matroxfb registered as adapter 0. i2c-core.o: adapter DDC:fb0 #1 on i2c-matroxfb registered as adapter 1. i2c-core.o: adapter MAVEN:fb0 on i2c-matroxfb registered as adapter 2. i2c-core.o: driver maven registered. i2c-core.o: client [maven client] registered to adapter [MAVEN:fb0 on i2c-matrox fb](pos. 0). matroxfb_crtc2: secondary head of fb0 was registered as fb1 TIA, Paul
