full-screen window mode doesn't work on lower of two monitors in extended workspace under Unity

[Christopher Barrington-Leigh]

Binary package hint: unity

Alt-F10, the default for expanding a window to full-screen, has no effect in the lower of two monitors in an extended desktop.
In the upper monitor, it snaps nicely back and forth to full screen. In Compiz / 10.10, it worked nicely by snapping to the local full-screen in either upper or lower display.

Hrm, I can't seem to reproduce this one. Can you explain what you mean by "fullscreen" here? I've tried both the bindings for fullscreen and /maximize/ (alt-f10) on both monitors in a top/bottom arrangement and I didn't see any problems.

Remarkably, this behaviour has changed a lot and for the better after a recent update (this week?).
 I assume that means I'm benefiting from backports. I don't have handy a system with the initial 11.04 distribution, but I think a lot of problems I've reported have been helped (without assignment from my bugs) since then. (It would sort of be nice to have launchpad reflect the real perfomance with which the distro went out, though --- presumably not everyone can update as easily).

So, if I drag a maximised window from my top screen to my bottom screen, it now jumps to maximised as it should (didn't before).
If I alt-f10 a window currently in bottom, it jumps to max in bottom, as it should (didn't before).
If I drag a window so that mouse is in top bar of bottom screen, I think I get a max state in bottom screen too, though I find it very difficult if the window is coming from the top screen (unmaximised).

There is still a problem with the bottom screen max state, though: the top bar of the window is missing/invisible (ie, behind the unity panel there). It remains visible and working properly when max'd in the top screen.
For instance, in Chrome, the tabs are invisible in the bottom max state. This problem exists for other apps too.

AFter yet another update, things got worse again! Actually, worse than ever. It's back to completely unusable external monitor. If I boot with it plugged in, I get multicolor flashing screen / unusable. If I plug it in after logging, the screen goes black and useless. If I unplug it to recover, I get a black responseless screen with an arrow cursor. I cannot recover and must reboot.
I'm back to early 1990s functionality now under the latest Natty updates. (Very very discouraged)

That sounds like an X11/Driver bug to me, not a compiz bug
