Bug Description
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.

Thank you for reporting this bug. matteo please do not confirm your own bug report. Some one else other than the original reported must confirm it.
Anyways, I have this problem on my system as well for the past week. Cannot figure out which package is responsible for this. Please let me know how I can gather more information to help the developers.
