[ltp] T41 dual monitor FC2

[nate]

I've had some success in FC2 getting dual monitor to work. I enabled 
dual head in the Display settings window. That gave me my lcd at the 
proper size, and my 17" crt monitor at 800x600 to the right of my 
laptop. I needed that switched, which (though irrelevant) is just drag 
in windows. However, I did modify the xorg.conf to say "leftof" instead 
of "rightof" and I've been somewhat happier. But 800x600 makes me feel 
trapped, so I'm hoping to fix the resolution on the crt. I read in the 
man page for xorg.conf that doing ctrl-alt-(numpad_-) will cycle through 
all the settings that are possible in the xorg.conf. However, I am a bit 
confused because what happens is my crt will turn off, and my lcd 
monitor decreases in resolution. That means that the line

 >Screen      1  "Screen1" LeftOf "Screen0"

tells me Screen1 is my crt, and Screen0 is lcd. But down lower xorg.conf 
says:

Section "Screen"
    Identifier "Screen0"
    Device     "Videocard0"
    Monitor    "Monitor0"
    DefaultDepth     16
    SubSection "Display"
        Viewport   0 0
        Depth     16
        Modes    "1400x1050" "1280x1024" "1280x960" "1152x864" 
"1024x768" "800x600" "640x480"
    EndSubSection
EndSection

Section "Screen"
    Identifier "Screen1"
    Device     "Videocard1"
    Monitor    "Monitor1"
    DefaultDepth     16
    SubSection "Display"
        Viewport   0 0
        Depth     16
        Modes    "1400x1050"
    EndSubSection
EndSection

Which means my crt should be at 1400x1050? It's at 800x600... (erm, I 
checked, but I forgot how, but it's obviously smaller than my lcd)
Should I just slap on "1280x1024" "1280x960" "1152x864" "1024x768" 
"800x600" "640x480" to the Modes for Screen1 and hope for the best? What 
am I missing here? The entire xorg.conf is posted below for reference.
Thanks,
Nate

# For example, a german layout can be obtained with:
