Hmmhhh... I really intensively tested now all the possible
configurations (single/dualhead with and without xinerama) and must say
wow! it is working very stably... I saw one problem once though, that
when I switch from X to console and used less to view some log file and
scrolled backwards, there was a stripe reproducing itself...
Unfortunately I cannot reproduce this... and I was unable to trigger it
again...

True... Indeed if I leave out the above Modes option and start X without
an external CRT but later on attach one, I also get some output on the
monitor... it is a bit darker in the top though (wrong mode...)...
With attached monitor the resolution of the external monitor is choosen,
which is why I felt like I need the Mode option... Maybe infact I don't.
I am still looking for 'the' solution, where one uses the internal DFP
most of the time then connects an external CRT/DFP and makes use of that
one without having to restart X...
I thought I could do this by using a multihead config with two displays
:0.0 and :0.1 but there I had the problem that the mouse cursor was
somehow only on :0.1 and I did not know how to set the mouse to be on
:0.0 ...
A different option would be to use a xinerama mode, and have a program
to somehow en/disable the mouse going to the external display...
Very good job Michael !
It is a pity that XFree86 is not yet capable of adding displays
dynamically like osx can... that would indeed "rock".
Thanks a *lot*,
Soeren.
