I don't get re-displays of previous OS's last monitor screens. This 
issue is definitely a Kubuntu shutdown issue and not a Win 7 initialise 
As I have said in another thread, I have to boot to Mandriva's kdm login 
screen and warm boot from there to get sound under Win 7 because 
Mandriva shuts down properly.
Also I am regularly in the situation of having to warm boot from Kubuntu 
to Kubuntu to recover from crashes of the flaky compiz version being 
used in Kubuntu, and having firefox tell me it can't start because the 
version that was active when I warm booted Kubuntu is still in memory 
and not responding and needs to be removed first.
