[Bug 1385572] Re: gnome-session not shutting down cleanly

[Tim]

** Description changed:

- We have had reports going back to 13.10 that gnome-shell extensions are
- disabled after restart (LP: #1236749), I've only just managed to
- reproduce this and have discovered that gnome-session is not shutting
- down cleanly.
+ [Impact]
+ We have had reports going back to 13.10 that gnome-shell extensions are disabled after restart (LP: #1236749), this has probably been our #1 unresolved bug for the last few cycles. While this is the main user visible bug probably other bugs caused by this for example (BGO: #745707)
  
- Basically, X gets shutdown, which causes gnome-shell to abort, following
- this gnome-session tries to respawn gnome-shell which fails and due to
- this failure disables all shell extensions. I don't know enough about
- upstart to really understand what is going on but it appears this also
- affects unity and it just hasnt been noticed since there are probably no
- such side-effects happening there.
+ The cause was tracked down to gnome-session not shutting down cleanly
+ under upstart. Although the underlying issue seems to be the order in
+ which upstart takes down the various components in a user session, the
+ side-effects themselves appear to be caused by gnome-session continuing
+ to run when it should in fact be shutdown
  
- Filing this against upstart since this is not reproducible when using
- systemd init, though it may well be a bug in gnome-session, but related
- to upstart user sessions.
+ The fix updates the 103_kill_the_fail_whale.patch to force shutdown of
+ gnome-session. This is inline with the fix upstream for (BGO: #745707)
+ also.
