This question came from our site for Ubuntu users and developers.

    
I guess they didn't want to deal with this over on askubuntu. Not auto-detecting the second monitor isn't so much of an issue. Check the xorg settings in an ubuntu 10.04 base install and see if manually adding that to an HD install of backtrack works. That's what I would do. –  hbdgaf Sep 19 '11 at 2:16
