I discovered that stopping my autofs5 service seemed to resolve this stalling, or at least one case where I was seeing it (Shutter not being able to load). I have not really figured out why.
My autofs config is simple, mounts a few NFS shares when I am on my home network, as well as a local drive when it is connected. #auto.master /shares /etc/auto.ianbmacdonald --timeout=120 --ghost #auto.ianbmacdonald media -fstype=nfs4,rsize=32768,wsize=32768,hard,intr,async media.ianbmacdonald.com:/data data -fstype=nfs4,rsize=32768,wsize=32768,hard,intr,async maple.ianbmacdonald.com:/data external -fstype=auto UUID="be2779cd-9607-46b4-a64f-92ec5894ec1a" Basically with autofs enabled, I don't see a complete list of folders in the left pane on most "open" dialogues, there are delays refreshing my evolution main screen, and shutter will not load (or takes minutes). It seems to be the culprit, although I have not seen the symptoms where desktop notifications get jammed up (as described above) in a very long time (maybe because I usually stop the service). I attached my xsession-errors from today (no autofs running); A few interesting things in there, notably with evolution, but nothing that seems related to this previous issue. ** Attachment added: "Xsession Errors" https://bugs.launchpad.net/ubuntu/+source/dbus/+bug/894766/+attachment/2721761/+files/.xsession-errors -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/894766 Title: DBus timeout stalling applications To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dbus/+bug/894766/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
