I have experienced this kind of slowing down when opening Synaptic. Opening Synaptic is delayed about 10 sec. It will open finally, however. I traced the bug to the package at-spi2-core (libatspi2.0-0 version 2.9.90-0ubuntu1) and possibly also to at-spi2-atk (libatk-bridge2.0-0 version 2.9.90-0ubuntu1).
After downgrading the packages back to the previous ones (versions 2.9.5-1ubuntu1 and 2.9.5-1) all is well and Synaptic opens immediately without any delay. I use the old d-bus (version 1.6.12-0ubuntu2) for the time being. I haven't tried the latest version 1.6.12-0ubuntu5 depending on libapparmor1 yet. I have a 64-bit setup with only Gnome-Shell DE. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to at-spi2-core in Ubuntu. https://bugs.launchpad.net/bugs/1217757 Title: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.NoReply: Did not receive a reply.
