tag 130191 + moreinfo thanks This debconf question has come a ways since I first created it.
Is the current template description and logic satisfactory?:
Template: xserver-xfree86/config/device/bus_id
Type: string
_Description: Please enter the video card's bus identifier.
Users of PowerPC machines, and users of any computer with multiple video
devices, should specify the BusID of the video card in the format:
.
PCI:nn:nn:nn
.
(where each nn is a decimal number referring to the card's bus, device, and
function number, respectively).
.
For users of multi-head setups, this option will configure only one of the
heads. Further configuration will have to be done manually in the X server
configuration file, /etc/X11/XF86Config-4.
.
You may wish to use the "lspci" command to determine the bus location of your
PCI or AGP video card. Keep in mind that lspci reports the bus, device, and
function numbers in hexadecimal, not decimal.
.
When possible, this question has been pre-answered for you and you should
accept the default unless you know it doesn't work.
.
Users of non-PowerPC machines with only one video card should leave this
entry blank.
