Comment 3 for bug 236210

@Dereck Wonnacott : The gdm restart was added for good measure, but why would you think to change the source package to Xorg? I do not think that this is an Xorg bug, rather separate bugs with bonobo-activation-server, gvfs-fuse-daemon, evolution-data-server, and gconfd-2. See Bug #49594, which is a dupe (but that report is limited to a discussion only of bonobo-activation-server; this report attempts to track all of the aberrant processes).

It seems that these processes are called by gdm, so a gdm restart gets us to a clean slate again. But these processes should, in and of themselves, know to terminate upon user log off. See a fuller discussion re: cleaning of GNOME processes at logoff at the link I posted here: https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/49594/comments/33
