I'm unhappy to further report that my dual monitors only work after I
log out and log back in after rebooting.
When I boot up my laptop monitor doesn't display anything. My desktop
is displayed on my external monitor. If my external monitor isn't
connected then I don't have any display at all !
I am hoping this gets fixed before the weekend as I have to take my
laptop on the road on Saturday morning.
However, if I log into a KDE session and then log out and log in again,
my laptop monitor comes to life. Someone forgot to initialize something
