Public bug reported:

Binary package hint: xorg

I hesitate to report this bug because it is (1) complicated to
reproduce, and (2) therefore not likely to occur.  Regardless, it does
happen and the only reliable workaround is to reboot my laptop.

To reproduce this bug, I need to:

   -- run my lucid laptop with two screens, one on :0 and one on :1,
that are different sizes, with the second screen connected via HDMI

   -- run virt-manager on the larger display (:1) and attempt to install
Windows 7 in a 32-bit virtual machine; all interaction with the virtual
machine must occur through the virt-manager GUI, not via VNC or other
method.

   -- walk away from the laptop and display long enough for the screen
saver to kick in (mine just blanks the screen), AND long enough for
power savings mode to kick in

   -- when you attempt to get the machine's attention by wiggling the
mouse or hitting shift on the keyboard, the only response is the cursor
flashing in the lower left part of the :1 display -- no password screen,
no actual control of the cursor (the mouse does not change the cursor
location),

At this point, the windowing system is completely unresponsive; logging
in from another machine via ssh and restarting gdm can sometimes work (X
does not always die), but more often than not it's necessary to reboot
the system.

If I run the same scenario but remove the second screen (i.e., do
everything on the laptop :0 alone), the screen does not lock up.  It's
also not clear that virt-manager is a key part of the issue -- I can
recreate it that way, but it has occurred under other circumstances
where I do not recall if virt-manager had been running or not.
