[Bug 1315842] [NEW] Compiz crashes Unity unexpectedly, no option for recovery

 

Public bug reported:

Sometimes it occurs that my Unity session crashes just like that - no
window decorations, no panel, but whatever was going on in the
background continues, like music playback. Problem is though it cannot
be restarted, since the option to kill the X server has been removed
from 14.04.

I did only minor alterations to Compiz, eg. bound the zoom function to
mouse buttons, added hotspots for expose to screen corners, changed the
number of screens from the default 4 to 6 (+2 vertical), fade effects of
windows, changed the drag button from ALT to Super,

yet it keeps freezing/hanging/crashing on a regular basis.
