nvidia card gives priority to "CRT", the external display, so, if you
plug an external screen/beamer, the display is on this one by default.

That was the case for the nvidia X driver, however never for the
hardware. And its no longer accurate for the driver. For many
notebooks, the internal DFP is given priority.

Nvidia readme:

<cite>

All mobile NVIDIA chips support TwinView. TwinView on a laptop can be
configured in the same way as on a desktop machine (please refer to
Appendix G); note that in a TwinView configuration using the laptop's
internal flat panel and an external CRT, the CRT is the primary display
device (specify its HorizSync and VertRefresh in the Monitor section of
your X config file) and the flat panel is the secondary display device
(specify its HorizSync andVertRefresh through the SecondMonitorHorizSync
and SecondMonitorVertRefreshoptions).

I'm not sure where you got this from, but its not true.

Maybe no longer true, if your laptop is new (mine is one year old) and
has a dvi connector. We can read in Nvidia readme:

<cite>

NOTE: anything attached to a 15 pin VGA connector is regarded by the
driver as a CRT. "DFP" should only be used to refer to digital flat
panels connected via a DVI port.

</cite>

Using Atrpms last dynamic compiled version of nvidia driver.
