Fail to repaint screen when external monitor attached while sleeping

[Amos Blanton]

Binary package hint: xorg

Steps to reproduce.
1. Put machine to sleep.
2. Plugin external monitor of higher resolution than laptop monitor (via external VGA port).
3. Wake computer.

Lower / left portions of desktop are displayed properly. Areas above and to the left of the desktop (that correspond to x,y values greater than the original screen size) do not repaint properly. They continue to display whatever content / application has been overlaid on them. See screenshot.

Possibly related config setting: The computer has been told to turn off laptop monitor when external screen is present.

Done some more looking into this. Turns out it only happens when:
System is booted without external monitor connected, then made to sleep, connected to external monitor while sleeping, then woken.

If the system is originally booted while connected to the external monitor, then it can be connected to an external monitor while sleeping, and this problem will not occur.

Hey amos-scratch,

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.

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.
