*) First I tried with my laptop, but I was not able to set up separate x screens. Found old message saying that intel does not support separate x screens - http://lists.x.org/archives/xorg-devel/2009-October/002447.html. Updated gnome-panel to version in proposed. Seems that with single screen gnome-panel still works ok, did not see any regression.
*) Installed 12.04 on flash drive. Updated all packages, installed gnome-panel, nvidia drivers. Tested gnome-panel before enabling proposed. Gnome panel did not work correctly with separate x screens. Enabled proposed and upgraded gnome-panel. I can confirm that this bug is fixed.

*) But there is two other bugs that should be fixed in my opinion:
1) White screen/background bug. I have proposed fix for that - https:/ /code.launchpad .net/~albertsmu ktupavels/ nautilus/ white-screen- fix-precise/ +merge/ 180232
2) Someone should backport fix for this bug - https:/ /bugs.launchpad .net/ubuntu/ +source/ xorg-server/ +bug/1068920.
