window maximisation fails in multiple ways in extended desktop

[Christopher Barrington-Leigh]

Binary package hint: xorg

using an extended desktop with one, larger display above the other, maximising a window (alt-f10) in the lower display sends it to the max state in the upper window.
Now, dragging the maximised window to the lower display results in various broken behaviour: the window shrinks to a strange small size, or sometimes expands to the size of the other display. But never does it dock to the lower display at the right size to be maximised there. And that is what it should do, to work like gnome and in the expected (or just not erratic) manner.

[Christopher Barrington-Leigh (cpbl)]

What a random excitement roller coaster is 11.04. After an update a week or two ago, window maximisation began to work much better. Sometimes it would still fail, but mostly, Alt-F10, for instance, would maximise a window in whatever screen it started. And to some extent I could drag a window from one to another in max mode, etc.

But after yesterday's update, that all stopped and I'm back to completely impossible to maximise in the lower screen.
Another symptom of this: If I maximise a window starting in the lower screen, it max's in the top, but the menu (if I press Alt, for instance) appears upwards from the bottom screen's top bar!!

[Christopher Barrington-Leigh (cpbl)]

Actually, it's worse. 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)

Hey cpbl,

You filed this bug report against natty, but I see it's still open and
doesn't appear to have much activity recently. So, now that oneiric
is released and stable, this may be a good point for you to upgrade
and re-test if this issue is still present there.

If it's solved in the new release and you think it's worth backporting
the fix, please indicate that. Or if having the fix in the new release
is good enough, feel free to close out the bug (or let us know and we'll
close it.)

If it's not solved, leave the bug report open. I can't promise we'll
get to it (we get way more bugs filed than we can usually get to), but
your testing and feedback can help out if and when we do.

[bugbot (bugbot)]

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.
