[Bug 1507764] Re: metacity crashed with signal 5 in _XEventsQueued() ; forcing gnome session to logout


About the packages, I am still using 15.04 Vivid (which means metacity
3.14), and it seems metacity and gtk+-3.0 will require a ton of
dependencies (glib, pango, atk, etc...), so I can't test these right

Here is what I get :
$ gsettings get org.gnome.metacity alt-tab-thumbnails
No such key 'alt-tab-thumbnails'

As for configuration, it seems I am still relying on CCSM (CompizConfig Settings Manager), which offers :
- Application Switcher
- Static Application Switcher (the one I use, which pops up with only icons)

Also, I don't think this is related but it feels like at times the
application switch is not instant (meaning, I need to wait a little bit
to be sure that it did switch, otherwise the keys I hit right after
Alt+Tab get processed by the previous application, which is kind of

  metacity crashed with signal 5 in _XEventsQueued() ; forcing gnome
  session to logout

Status in metacity package in Ubuntu:

Bug description:
  This bug seemed to occur already since earlier versions of Ubuntu, and
  usually would just end up leaving me with undecorated windows, from
  which recovery was as easy as restarting metacity by hand, but in this
  release of Ubuntu (15.04), it seems gnome-session tries to restart it
  too many times in a too short span, and then decides arbitrarily that
  it failed so bad it has to kill the whole session.

  So, while the metacity bug is really a thing, my real problem actually might be a gnome-session-bin bug.
  I expect metacity crashing would not bring down the whole session, as is the case currently.

  At any rate, this is extremely annoying, I am hitting this bug about
  every two days, and because of it and the regression in crash
  handling, I end up losing all my windows and running programs. (In all
  fairness, I am suspecting a hardware issue, but the problem remains
  that a sub process dying should not cause the parent process to die
  like this)
