My laptop just ran some updates, and when prompted to restart, I did.
Now my CPU is maxing out, and my battery barely lasts 20 minutes. The processes that are going crazy are:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

This has happened once before, about a year ago, but I can't remember how I fixed it. I do remember upvoting this question/answer, but the solution there doesn't work for me now (and I think I upvoted it because it was a step in the right direction, not a solution itself).
When I run dbus-monitor --system I see a lot of NameOwnerChanged events. Here's some sample output from dbus-monitor --system "member=NameOwnerChanged":
signal sender=org.freedesktop.DBus -> dest=(null destination) serial=376312 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameOwnerChanged
string ":1.191451"
string ""
string ":1.191451"
signal sender=org.freedesktop.DBus -> dest=(null destination) serial=376313 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameOwnerChanged
string ":1.191452"
string ""
string ":1.191452"
signal sender=org.freedesktop.DBus -> dest=(null destination) serial=376314 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameOwnerChanged
string ":1.191452"
string ":1.191452"
string ""
There's about 100 NameOwnerChanged events coming through per second.
It's very frustrating. What should I try next?
