That file needed to be generated in the past, but it's no
longer needed (and even the location is not correct anymore,
today you can use a /usr/local/etc/X11/xorg.conf file, or
partial files in /usr/local/etc/X11/xorg.conf.d/ with
configuration fragments).

For example, if you want to force a specific screen size
("resolution"), you could use the following:


	Section "Screen"
		Identifier "Screen0"
		Device "Card0"
		SubSection "Display"
			Modes "1024x768"

I use this to have a laptop with a native LCD size of
1280x800 to display correctly on a 4:3 CRT attached at
the docking station.

You can use the xrandr program to manually switch to the
screen you want. Then add that to your X startup file,
~/.xinitrc or ~/.xsession, so it will automatically use
the desired monitor when you start X.

With xrandr, you can also alter the size ("resolution")
parameters of the screen, if needed.

However, most of all this stuff should be correctly
autodetected by X.

"Desktop with icons on the screen" is a matter of the deskto
environment, not of X. Most desktop systems will arrange the
icons depending on the screen parameters they find.

Always check mixer settings, levels, selected recording device,
and for the program in use, which sound system it uses (for
example, OSS or ALSA).
