[Bug 1511095] Re: unity-system-compositor crash, no interaction on windowed mode

 

The stack trace shows a crash in
mi::DisplayInputRegion::bounding_rectangle() because we don't have any
displays in the region. A fix for the immediate crash is at:

>From the supplied info I can't tell if not having any detected active
displays is a valid situation or it's indeed a problem and the root
cause of what we are seeing. Whatever the case we shouldn't crash like
this, so this fix is a definite improvement, even if it turns out not to
be a final fix.

Bug description:
  I am seeing this occur with Nexus7 (i haven't tested with nexus4 enough to say)
  but I regularly see N7 reboot with me having interacted with it

  I will have usually connected the BT mouse and have maybe u-s-s open as well as dash (i think i've even seen it do so after just being rebooted with me not touching it before the next reboot).
  the screen will be on or off from being idel, no interaction per se and the device will suddenly display the "spinner" screen which is actually ubuntu dot-dot-dots

  I have seen it enough to confirm there are no crash files
  generated/associated with it

  lastly, i have seen this mostly while i have added silo21 (unity8
  improvements) on top of the latest pd image.

  attached is a syslog
