laptop display on externel screen

Hello, I'm installing Fedora version 2 on a Dell Latitude x300.
The kernel has been upgraded to 2.6.8.1 and compiled with support
for acpi. Support for apm is disabled.
The Fn+(CRT/LCD) button doesn't work, but I have installed the
program i810switch, which (should) enables control of whether the
displayimage is send to the laptop LCD, to an external display/beamer,
or both.  

Connecting to an external display and running
"i810switch crt on"
makes the displayimage visible on the external screen. However:
on the external screen the image is extremely blurred (flickering like
when wathcing a start). It is fully recognisable as a copy of the
laptop lcd image, but too blurred to be of practical use when
giving for example a presentation using a videobeamer.

It isl like the graphics board should normally automatically have made some
fine tuning of the frequencies
when sending to a new device, but  didn't do so (I'm guessing -
it has never been a problem before with other laptops I have used).
I have tested the functionality against both an external LCD monitor and
against a videobeamer. The result is the same in both cases.

When called the i810switch program reportts an error:
"no LCD support for this chipset"
which is kind of funny as it is  showing on the laptop lcd all the time. But
is cannot stop that ("i810switch lcd off" doesn't change anything, but
that's not a problem to me).

With thanks for your help, Henrik

That is a i855GM, so... according to http://vorlon.cwru.edu/~ames/i810switch/ you should perhaps try get something workable from the i855 crt project (http://i855crt.sourceforge.net/ ... or rather http://sourceforge.net/projects/i855crt) since you fall into the category (flicker and generally bad output...).
A bit experimental, but unfortunately the best there seems to be:).
