** Description changed:
- 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:
