Dual monitor - how to save settings?

[Amedee Van Gasse (ub)]

Hello,

I have two monitors, both connected to the same graphics card:

VGA-0: 1280x1024
DVI-0: 1920x1080

When I boot up, they are both in 1024x768 and show the same output.
I use xrandr (or whatever frontend Gnome or KDE provides) to change them
to their native resolution (their 'automatic' setting) and the DVI-0 to
the right of the VGA-0 so that I get one huge desktop.

After rebooting I always have to reconfigure this, my modifications aren't
saved.

I have tried to find recent documentation, but most of what I found was
for Ubuntu 6.06, and I seem to remember that there were some significant
changes in X in the last couple of years.
