This will work
fine if the actual monitor capabilities can be probed, which is the case for most modern
monitors and some laptop screens. However, this will not work if the monitor is
not on when the X server is started, the monitor does not report its capabilities, or special
video hardware is in use, such as a splitter to connect both a monitor and a video
projector, or a keyboard/video/mouse (KVM) switch. In those cases, the scan rates that
the monitor can accept must be specified in this section (Section 3.14).
Because older monitors could be permanently (and sometimes spectacularly) damaged
by sending a signal with the wrong scan rate, the X server is conservatively programmed
and will exit rather than guess what scan rate to use.
Device
The Device section needs only two basic entries:
Section "Device"
Identifier "Videocard0"
Driver "nv"
EndSection
The entries are:
Identifier
The name given to this video card, which is referenced by a Screen section.
Driver
The name of the device driver to use. This is determined automatically by scanning
the PCI and AGP buses when you run the server with the -configure
option. To see the X server??™s view of the buses, use the -scanpci option:
$ X :1 -scanpci
I used display :1 here to avoid conflicting with display :0 if it??™s already running.
