here is the command to identify video cards
# pciconf -lv | grep -A 4 vga
Code:

I also tried the automatic configuration but without a positive result
/usr/local/etc/X11/xorg.conf.d/video.conf
Code:
Section "Device"
      Identifier  "Card0"
      Driver      "radeon"
      BusID       "PCI:0:1:4"
EndSection
I can not properly configure the xorg.conf, card under FreeBSD we process the automatic configuration with the files having ".d" endings, so I can only switch to manual configuration, i must to configure the xorg .conf!
So I have two video card and two screen output, which I choose so I have ²16 solutions, how to choose the right video card and the good screen?

Philippe
