[NTLUG:Discuss] Multi-Head on Dell Inspiron 4100 w/ GeForce2Go chipset

[David Simmons]

Guys,

Need some help configuring a multi-headed setup.  I have a laptop with
external monitor connections.  I've confirmed under Win2K that the
laptop/chipset can do a multi-headed/spanned display (under windows).

When I boot into Fedora Core (yes, version 1 - hope to upgrade, but
since this machine 'normally' is just email - no real hurry except that
it's my ONLY machine for this week while away).

Went to NVIDIA to grab latest/greatest - won't help because it's X.org
based - while Fedora Core uses Xfree86.  I've configured the display
both with the 'helper display app' and hand-configuring the
/etc/X11/XF86Config file....no luck because even though second display
comes up - it's got funky colors ASCII characters....they do change if I
change what's on main screen).

Help!?  I've included the 'booted' XF86Config file - as it should be
configured LCD as primary with CRT (external) as secondary - but it
wants to keep rewriting it?  Maybe that's the source of my
issues)....either way, here's /etc/X11/XF86Config:

# If you have a US Microsoft Natural keyboard, you can use:

# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#	Option	"XkbLayout"	"de"
# or:
#	Option	"XkbLayout"	"de"
#	Option	"XkbVariant"	"nodeadkeys"

# If you'd like to switch the positions of your capslock and
