Public bug reported: So it used to be that when unity/compiz crash, which sadly happens to me about once a week, compiz would get respawned, causing maybe a few seconds of the session being frozen but then having everything back to normal.
This is unfortunately not the case with Yakkety. When the same issue happened to me again earlier, compiz did get respawned properly but I lost all my open windows. I don't believe that this is the same issue as https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1613297 since compiz crashing means it'll be respawned by whatever manages it and that's typically done in the exact same process group, which is pretty different from killing compiz and spawning a new one from somewhere completely different in the process tree. This may be related to the switch away from upstart user sessions over to systemd user sessions and the way systemd tracks and kills tasks. I suspect this can be reproduced by killing (possibly with SIGSEG) unity-panel-service or even just compiz itself. Here it's usually unity- panel-service that's misbehaving, dies and takes compiz with it. ** Affects: unity (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1632386 Title: On yakkety, a unity crash and respawn kills all windows To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1632386/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
