Comment 0 for bug 1347272

I seem to be hitting transient DBus communication problems after a fresh install of Xubuntu 14.04 amd64 on my Thinkpad W510 with the latest nvidia binaries from the Ubuntu repos. Here are the related bugs. Sometimes rebooting fixes things for a while. If I understand correctly, at least one of the bug reports (Bug #1314782) suggests a race condition is to blame:

Bug #976638 (pkexec does not find any authentication agent)
Bug #1193236 (Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-*)
Bug #1239014 (xfsettingsd unable to daemonize properly when overlay scrollbars are activated)
Bug #1048805 (xfce4-appfinder launches very slowly)
Bug #1314782 (multimedia keys don't work when xfce4-volumed is run in daemon mode)
