Device Section - HP zx2000 Supplementary Manual

Device section

The configuration file may have multiple Device sections. There must be at least one, for the
video card being used. Device sections have the following format:
Section "Device"
Identifier
Driver
VendorName
[BusID
Option ...
. . .
EndSection
The Identifier entry specifies the unique name for this graphics device. It must match a DriverID
in the active Screen section.
The Driver entry specifies the name of the driver to use for this graphics device. When using the
loadable server, the driver module "driver" is loaded for each active Device section.
Supported drivers are:
firegl23, radeon
The keyword BusID specifies the bus location of the graphics card. For PCI/AGP cards, the
busid string has the form PCI:bus:device:function. This field is optional in single-head
configurations when using the primary graphics card. In multi-head configurations, or when
using a secondary graphics card in a single-head configuration, this entry is mandatory. Its main
purpose is to make an unambiguous connection between the Device section and the hardware it is
representing.
To find the bus ID of the graphics device you can use the command
ioscan -f | grep gvid
Beginning with the December, 2002 X Server patch, the brokering mechanism is supported and
the Driver and BusID keywords are no longer supported in the "Device" section. They have been
replaced by the Devicefile keyword. The Devicefile keyword identifies which character device
provides the interface with the actual hardware. The device should be a /dev/gvid device
(for example, /dev/gvid0, /dev/gvid1)
Options are device dependant and should be searched for in device specific sections of this
document.
