Bug Description

I have powered on the pc as usual, the screen shown only the mouse cursor, the rest was black.
I have tryied to restart lightdm service (ctrl-at-f1, login, sudo lightdm restart), but the drawer shown only "labels", no input or buttons was displayed, only the baloon with the login name and the background.
ctlr-alt-f(x) does not worked anymore

Using ctrl-alt-canc i have rebooted the machine, at the first login the error report apperaed.
