brant interactive

I got dual monitors working well, except the two screens were basically duplicates - each screen having its own desktop, and control panels. Plus, it wasn’t possible to drag windows between screens. Adding the Xinerama option as shown below seems to have fixed this issue.
(from /etc/X11/xorg.conf)

Section "ServerLayout"
        Identifier     "Default Layout"
        Screen         "Default Screen" 0 0
        Screen         "aticonfig-Screen[1]" [...]

Another crumb for the setup path…
You’ll need to create a symlink to irb to run the console:

ln -s /usr/bin/irb1.8 /usr/bin/irb

The Ruby OpenSSL bindings are not installed by default on Ubuntu and Capistrano needs them.. so if you see this error:

`gem_original_require': no such file to load -- openssl (LoadError)

run this command(you probably already have the openssl library, but not the Ruby bindings):

apt-get install libopenssl-ruby
