Dual Display problems in 12.10 and Raring

[Colin Law]

Is anyone using dual displays in Raring alpha (or 12.10 for my second
issue) seeing the problems that I am?  Firstly, with the launcher on
the right hand display it is impossible to place anything (shortcuts,
files etc) on the left hand display, they bounce back tot the right
hand one when an attempt is made to place them there [1].  This is a
new bug on Raring.  The second one however [2] is equally annoying and
has been around since 12.10.  If, for example, two firefox windows are
opened, one on each display, and the FF launcher icon is clicked then
the focus always goes to the one on the same display as the launcher,
whichever FF window last had the focus.  This is not specific to FF,
it applies to any application.

No-one so far has confirmed the bugs.  There was a big push to get
dual display support working well for 12.04 (if I remember correctly)
but things seem to have gone downhill since then.

I am using Intel graphics.
