Yes, and it was a long journey with my X40.

Using Fn-F7 through ibm-acpi gave me about 20 pixels of garbage
at the top of the screen.

Using i855crt worked, but the mouse cursor would stay fixed at
the upper left corner on the monitor output.

i810switch worked, but with very poor video quality on the
monitor output.

Then I found another xorg.conf and a script that somehow
'copies' the contents of the LCD to the external Monitor
via vnc. Worked, but awfully slow.


The following xorg.conf seems to work flawlessly: X just
clones the display on the monitor output. No need to
connect the monitor prior to starting X, no problems with
S3 Sleep and Software Suspend2 ...
The only drawback is that overlays (e.g. xine) are displayed
only on the internal LCD. Don't know how to fix this. It Would
be nice to switch the overlay from internal to external
display with some script...
