This may be of some interest to those struggling with second screens.
I recently modified my xorg.conf following information given in
<http://www.thinkwiki.org/wiki/Xorg_RandR_1.2>. The basic proposition
is that xorg.conf kludges should not be needed to get clone or dual
monitor setups. I based my xorg.conf on one generated from
Xautoconfig with some of the modifications suggested in the above
document (mainly the visual line). With this done I could plug in an
external monitor to my iBook and get a display doing (for example):
xrandr --output LVDS --auto --output VGA-0 --auto --same-as LVDS
or
xrandr --output LVDS --auto --output VGA-0 --auto --below LVDS
For all fonts to diplay correctly the generated xorg.conf assumes all
font directories are found by the X Font server. I ensured that all font
directories were added to /etc/fs/config using:
chkfontpath --add directoryname
After this I ran (i) mkfontdir on each directory and then ran (ii)
'fc-cache -fv'.

# RgbPath is the location of the RGB database. Note, this is the name of the
# file minus the extension (like ".txt" or ".db"). There is normally
# no need to change the default.
# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.
