same issue here with thinkpad W500 it was working fine almost 45 days ago but not anymore with ubuntu although works with vista

in Xorg.0.log i noticed this "invalid output device for dac detection"

attached part of the log when i start to mirror the screen.

btw during the boot i see dual screen working on laptop and the external ThinkVision L220x but the moment login screen of ubuntu shows it disabled the external monitor although ubuntu's boot logo shows
