Most of the processes you're seeing are run by the session upstart. Try 'ps fax' to see the process tree. You also get to see what state these processes are in that way.
Still, this has nothing to do with Unity, which neither handles system power states nor session process control. You might want ot check logs in /var/log/upstart or ~/.cache/upstart for more clues. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity in Ubuntu. https://bugs.launchpad.net/bugs/1427785 Title: Duplicate processes started after Resume of amd64 bit Status in unity package in Ubuntu: New Bug description: $ uname -a Linux ajsc855 3.13.0-46-generic #76-Ubuntu SMP Thu Feb 26 18:52:13 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux $ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=14.04 DISTRIB_CODENAME=trusty DISTRIB_DESCRIPTION="Ubuntu 14.04.2 LTS" Toshiba Satellite C855, 4GB RAM, 720GB HD I typically run Thunderbird, Firefox, a terminal or two, Gthumb, Gimp, Qcad, Gedit, Libreoffice, Inkscape, Document Viewer and occasionally Virtualbox. I just noticed this a couple of weeks ago, so I am guessing a recent update started it. It seems to me that there are quite a few duplicate copies of some processes populating memory after suspending/resuming a session for a few days. Namely, dbus-daemon, gvfsd and gconfd-2. The more I suspend/resume the session, the more of these processes appear. After a while they start using up a significant amount of memory and system response seems to slow down. Logging out and back in did not alleviate the problem. Rebooting did. But, I will have to reboot again in a week to free up the memory used by these duplicate processes. The example session used to get the following results was probably well over a week in use. Before rebooting: $ ps -ef >prereboot.txt $ grep -i dbus-daemon <prereboot.txt|wc -l 40 $ grep -i gvfsd <prereboot.txt|wc -l 78 $ grep -i gconfd-2 <prereboot.txt|wc -l 37 After rebooting: $ ps -ef >postreboot.txt $ grep -i dbus-daemon <postreboot.txt|wc -l 4 $ grep -i gvfsd <postreboot.txt|wc -l 5 $ grep -i gconfd-2 <postreboot.txt|wc -l 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1427785/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
