Thanks for your response.

I don't seem to be having any luck. When I lift the machine out of the port 
replicator II the LCD does not show the display. I tried Fn-F7 but no joy. I 
changed the BIOS settings to be VGA+LCD but that didn't help. I tried using 
the /proc/acpi/ibm/video switches but I could only unset 'auto', not enable 
any other modes.

I wonder if it has to do with the different refresh rates of my 19" CRT and 
the laptop's LCD -- maybe the video card is too smart to attempt to drive the 
LCD with the CRT's settings?

Cheers,
John
