Jaunty set up my dual monitors out of the box without me having to lift a finger.

In Karmic my second (vga) monitor is assigned as the primary with the launch bar and dock appearing there, which is a little annoying as i have to keep both monitors on even if I only need one.

Anyone know what has changed between releases to cause this and know how I can solve it?

I've seen similar problems listed for nvidia cards, the solution was to issue twinview specific commands in xorg.conf to assign the primary monitor to the dvi output. Anyone know if a way i can do this for ati?

I tried installing fglrx and the proprietry drivers from the ati site, both resulted in blank screens after login.
