Chris, Colin,

Thanks for your replies but "tick the box" and "System, Preferences,
Monitors" don't have a lot of meaning for me, because I constantly switch
between Gnome, KDE, Xfce, Openbox, Ion, Awesome, Fluxbox,... I have a bit
of a Frankenbuntu, but it all works just fine.
I am not familiar with the common Ubuntu abstraction layers imposed by the
GUI. However, I *have* used "System, Preferences, Monitors" in Gnome
(which is just a fancy graphical front end for the xrandr commandline
utility), and it is not remembered. So there is my problem.

Is there anyone on the list who knows about xrandr?
