Public bug reported: 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:
