Public bug reported:
Dual monitors with both monitors connected via DVI to a dual head nVidia
GTS250 card. However, xrandr thinks that the secondary monitor is an
HDMI connection:
nick@PreciseBeta2:~$ xrandr
Screen 0: minimum 320 x 200, current 3640 x 1920, maximum 8192 x 8192

I get a desktop across both monitors ok with the Nouveau driver, which I
am using, but if I switch to the proprietary nVidia driver, I cannot get
a display on the secondary monitor.
I also have 10.04 installed on the same machine, and booting into it and
running xrandr shows the expected DVI connection for both monitors.
