Please try again with 1:6.7.194-1 currently in experimental. It should
be much better than 6.6.3 and 6.6.193 for dual-head since it supports
RandR 1.2 which enables dynamic enabling/disabling/resizing/moving of
multiple outputs. You need to update your xorg.conf for RandR 1.2. See
http://bgoglin.livejournal.com/9846.html,http://bgoglin.livejournal.com/10214.html
and maybe http://bgoglin.livejournal.com/10423.html too. If it does not
work, please send your config and log from this version, and also the
output of xrandr right after starting X.
