Screwed up desktop

[S. Patrikios]

At first the user selection and password remained visible on the desktop even after logging in.
Trying to take a snapshot would turn the desktop simply white. Top panel active, though not visible.
Rebooting corrected nothing.
 Eventualy turning off froze completely.
And then... this was the desktop I faced (see attachement).
