Description Harald Judt 2011-12-02 15:14:51 UTC 
This might not be a bug, but a few kernel revisions ago, DVI-0 became active:

What's this DVI-0? LVDS and VGA-0 (when connected) work fine, and DVI-0 does not hurt, but still I thought I'd report this here in case this shouldn't be as it is now ;-)

It's on a docking station.  As to why it's suddenly getting detected, can you bisect?
