I'm not sure, that this is so.

It is the main problem discussed here. When the initial virtual size (e.g. set
to 1600x1200) is too small to include my dualhead display (e.g. 2048*768), then
it fails to set it - "... it must fit in virtual resolution".

I have to shut down X, modify xorg.conf (add VirualSize ...) and restart X.

... no "dynamically resize" :-(
