Currently my xorg.conf.d directory contains the following config:
$ cat /etc/X11/xorg.conf.d/*
Section "Device"
Identifier "Radeon Graphics"
BusID "PCI:1:0:0"
EndSection
Section "Device"
Identifier "Intel Graphics"
BusID "PCI:0:2:0"
Driver "intel"
Option "AccelMethod" "sna"
#Option "AccelMethod" "uxa"
#Option "AccelMethod" "xaa"
EndSection
Is the BusID line in the intel device section not needed? What is needed for X
to automatically detect multiple GPUs properly and show some video output from
the correct card?
