Dual Monitors no longer working

Hey there, I've been without net for a few weeks so I haven't done a full system upgrade in about a month. I normally have two monitors running just great using TwinView but I've recently picked up a new monitor that I'm using to replace one of my older monitors in my setup. Using the same xorg.conf (didn't think much, aside from naming the device, needed to be changed) so I plugged it in and all that fun stuf,f got it set up right, and I'm able to view the monitor that isn't showing up when starting X during boot and while starting up. What's strange is that I've had a different, crappy, monitor plugged in and started x and it worked fine and while X was still running I plugged in my current "to be desired" monitor and it worked! Though when I restart X I can't use it anymore. I'm not sure where to start with this one, I'm a bit of a noob so hopefully someone can lend a hand.

This is my xorg.conf

# XFree86 4 configuration created by pyxf86config

Section "ServerLayout"
    Identifier     "Default Layout"
    Screen      1  "Screen1" 1 1

    InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "Files"

# 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.

#    Option    "XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults).  For example, for a non-U.S.
# keyboard, you will probably want to use:
#    Option    "XkbModel"    "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
#    Option    "XkbModel"    "microsoft"
#
# 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

Re: Dual Monitors no longer working

I've never used twinview, but I would like to see this figured out.  My guess is that maybe the LCD isn't reporting to the comp correctly?  Maybe you should check dmesg for anything about either?  I know some have DSDT issues, and plugging in the old monitor before means it's probably erroring out on something small and fixable when your have the new monitor in.

G'luck.
