We put applications in cgroups to ensure that their PIDs don't escape and we can kill them all when the app shuts down.

Re: [Bug 1535058] Re: applications close instantly when launched from the launcher or dash
@David, please look at /etc/pam.d/common-session. Do you by chance have libpam-cgm rather than libpam-cgfs there? libpam-cgfs does not require cgmanager running On the other hand if unity8 itself requires it, then that's that. And yeah, i guess I do have cgmanager running on my laptop, so I've not tested it without. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1535058 Title: applications close instantly when launched from the launcher or dash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cgmanager/+bug/1535058/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I have no idea, unfortunately i've not been able to get far enough with unity8 to reproduce this. Could you please restart cgmanager with the --debug command line option, reproduce, then send me the debug log? Also show the /proc/self/cgroup output for the task (upstart?) that does the failed firing off of apps.

Re: [Bug 1535058] Re: applications close instantly when launched from the launcher or dash
What file or dbus call is used to start the upstart job? Why is upstart requiring cgroups? Is it something you want/need, or is it being done inadvertently? If it's something you need, then unity8 or one of its pieces must depend on libpam-cgm (soon libpam-cgfs). If not, then we should figure out where the dependency is coming from, as it would be better to not require the extra package if unneeded, obviously. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1535058 Title: applications close instantly when launched from the launcher or dash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cgmanager/+bug/1535058/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
