Version 304 says: "WARNING: This is an unstable beta driver.  This
package is intended for testers and early adopters, and not recommended
for production hardware."

Are you seriously suggesting I should use that? Given how unstable the
current "stable" version is, I don't dare imaginge how a version that is
explicitely declared "unstable" can be.


Anyway how can this possibly be a graphics card driver issue by the way?

Happened again just now. I'll do an apport collect, hope it provides
some useful data.

** Changed in: unity (Ubuntu)
       Status: Incomplete => Confirmed

** Tags added: apport-collected

** Description changed:

  I had a few applications open, namely:
  - Google Chrome
  - a Nautilus window
  - Gedit
  - a terminal
  
  Suddenly, after clicking on Google Chrome to give it focus, the whole
  system hanged and I couldn't give focus to any other window, nor close,
  minimize or move the current focused window (which was Chrome), nor do
  anything.
  
  - CPU consumption wasn't high (I can tell because the fan cooler wasn't 
running fast)
  - the Google Chrome maximized window, to which I had just given focus, was on 
front
  - I could see and move the mouse cursor, but wherever I clicked or dragged, 
nothing happened at all
  - Moving the cursor to the top of the screen would NOT show the window's top 
buttons nor the application menu
  - moving the cursor to the left would not show up the Launcher
  - alt+tab wouldn't switch to another window
  - Ctrl+Super+D would not show the desktop
  - left or right-clicking anywhere did nothing
  
  I couldn't save the files that I was editing in Gedit, so I lost a huge
  lot of unsaved work.
  
  Additionally, because of bug #1016457, I couldn't even open a virtual
  terminal and try killing some process or anything.
  
  The KEYBOARD DID RESPOND, in some way, meaning that for example:
  - the Ctrl+Alt+M shortcut that I have associated to the touchpad-indicator 
program did work and would disable and reenable the touchpad
  - Ctrl+Alt+F1 did show a black screen (which is what usually happen, because 
of bug 1016457, instead of showing the virtual terminal)
  
  However neither Alt+TAB nor Ctrl+Super+D (show Desktop) worked.
