Comment 10 for bug 754337

There are serious issues (design issues I think) with multi-screen configuration in Unity:

* No way to choose (using pointer device) primary screen (suppose the primary screen is the one with launcher). Workaround: xrandr --output VGA1 --primary
* Multiple issues with vertical layout with primary screen on top:
 * Only way to move the window past the top panel of bottom screen is using Alt key.
 * When resizing windows from the bottom screen by mouse, the corresponding apps crash (resizing with Alt+middle key works).
 * When maximizing windows from the bottom screen by mouse or Alt-F10, the windows are maximized on the top screen,
 * When apps are lanched on the bottom screen, they're window title-bar is hidden behind the top panel,
 * No way to hide the top panel on the bottom screen (I consider this a bug). Also, hiding the top bar would be probably a workaround to most of the above bugs, similarly to removing top bar from the bottom screen in vertical dual-screen setup with GNOME).

If you need visualization, I can make a video for you to show how messy this is. In my opinion (because of the above bugs) Ubuntu 11.04 should be still BETA.
