Hi Robert,
I have the same situation, and used the xrandr script which Marko posted
a couple of weeks ago. This turns off the laptop screen on startup, BUT
anything which was on the laptopp screen gets "lost" ie, I can't refer
to anything which was in the trays. If I then click on the cashew on
the external screen & hit "zoom out", it shows me 2 screen images, the
one I am using on the external screen (with the "blue blob"background),
the other which appears to be the last laptop image with a plain blue
screen.
My previous F11 installation used to have the same image on both
screens, which I could "auto config" on my external screen to get it to
full screen & Fn-f5(Toshiba) would cycle happily throught the
both-ext-lap.....
So far, I've not found an answer!
