in decimal form, but lspci displays these in hexadecimal form. The value of
BusID is automatically detected by SaX2.
The value of Driver is automatically set by SaX2 and specifies which driver to
use for your graphics card. If the card is a Matrox Millennium, the driver module
is called mga. The X server then searches through the ModulePath defined in
the Files section in the drivers subdirectory. In a standard installation, this
is the /usr/X11R6/lib/modules/drivers or /usr/X11R6/lib64/
modules/driversdirectory. _drv.o is added to the name, so, in the case of
the mga driver, the driver file mga_drv.o is loaded.
The behavior of the X server or of the driver can also be influenced through additional
options. An example of this is the option sw_cursor, which is set in the device section.
This deactivates the hardware mouse cursor and depicts the mouse cursor using software.
Depending on the driver module, there are various options available, which can be
found in the description files of the driver modules in the directory /usr/share/
doc/package_name. Generally valid options can also be found in the manual pages
(man xorg.conf and man X.Org).
26.1.3 Monitor and Modes Section
Like the Device sections, the Monitor and Modes sections describe one monitor
each. The configuration file /etc/X11/xorg.conf can contain as many Monitor
sections as desired. The server layout section specifies which Monitor section is rel-
evant.
Monitor definitions should only be set by experienced users. The modelines constitute
an important part of the Monitor sections. Modelines set horizontal and vertical timings
for the respective resolution. The monitor properties, especially the allowed frequencies,
are stored in the Monitor section.
WARNING
Unless you have an in-depth knowledge of monitor and graphics card functions,
nothing should be changed in the modelines, because this could cause severe
damage to your monitor.
