How do you completely reset monitor configuration (e.g. what used to be dpkg-reconfigure xserver-xorg)?

Question

Using unity 11.04. I have a secondary monitor (actually two, one at home, one at work). The home twin monitor set up works perfect (Viewsonic monitor). At work, I get very buggy behaviour, such as full screen applications 'ghosting' when maximized, and other strange effects. I would like to try and completely reset the monitor configurations (not unity or compiz), before doing anything else. In 10.10 this would be accomplished:

dpkg-reconfigure xserver-xorg

If you think it's some user preferences settings, then you can create a new user "temp", login as a "temp" and see if it's ok.

You can also try xrandr --auto.
