Thanks so much for your help.
I tried "nvidia-setting" to detect the display, it works and can detect the connected display.
But there is another issue about the resolution:
My laptop (DELL D630) is 1280x800, the connected LCD monitor is 1024x768, thus only parts of laptop screen are shown on the LCD monitor.
I wonder if there is a way to change the resolution of the connected LCD monitor or projector? I tried to use "xrandr --output VGA --mode 1280x1024", the xrandr seems
doesn't work on my laptop because nothing happens after I ever execute
the "xrandr" command to switch my screen.
Thanks a lot
Michael

"not entirely true": xrandr --auto should find all connected monitors
and enable them (in this case the laptop AND the projector). This would
work even if you plugged in the monitor/projector after you powered up
the lappie and entered X first. Now, I don't know the version of xrandr
in Lenny, so perhaps this will not work, but I think it will.
