  Summary: Unity 3D desktop crashes in Oneiric using ATI Mbility Radeon
  X1600
  
  Problem: 
  There doesn't seem to be rhyme or reason to this, be it having Firefox running, opening a link in Chromium to open in a new tab or watching a .flv video clip, using the subcontextual menus of Thunderbird, or watching videos in Totem. The desktop crashes bringing one to the login screen.  Sometimes the desktop crashes as it's appearing.
  
  The last thing one sees is a black screen with text, and something about
  Pulseaudio, but I'm not sure it's an error as I see no red text (just
  white), and there's no time to read it before the login screen appears.
  
  
  Steps to reproduce:
  Login using Unity 3d.
  Use your system.
  
  
  Results
  The desktop crashes
  Login screen appears
  
  
  Expected results:
  No crashes.
  
  
  Comments:
  At one point I thought the problem was due to indicator-weather, but I removed it, and although crashes became less frequent, they increased drastically two days ago (after updating).
  
  This behaviour was non-existent in Natty.
  
  I went a whole day without this behaviour by logging in using Unity 2D,
  and went along using all the above apps to no crashes.
  
  I noticed there is a history of problems with Radeon video drivers, but
  they didn't describe this type of crash, and they seemed to be fixed in
  Natty, which makes me think it might not be a regression.
  
  The only other issue I can think of that might be related is that
  turning compiz plugins on and off (Widgets Layer, and Zoom Desktop),
  presumably the non-default one, crashes Unity. I looked into it and
  sources say that this could be an issue with my video card, which I find
  outrageous considering it's only a few years old (well within the 5 year
  margin for compiz support), which points to a faulty driver and/or lack
  of proper driver support.
  
  System Info lists my graphics support as Gallium 0.4 on ATI RV530. I
  found that odd. Wikipedia says that the my video card, although based on
  the RV530, is NOT the ATI RV530. So, I don't know if it's a matter of
  the wrong driver being assigned and there's no longer a Xorg.conf file
  to check, so I'm at a loss.
