I'm running 13.04 on an acer c7 (chrubuntu 12.04 install then two system upgrades) and now whenever I use my computer for more than a few minutes, it slows down as polkitd, dbus-daemon, console-kit-daemon, and networkmanager chew up all my system resources. I tried googling this issue but it does not seem to be very widespread, or I'm just missing something.
I've tried looking at my system logs but nothing seems especially unusual there. I've also tried looking at the dbus-monitor. I'm not completely sure what I'm looking for there, but there does not seem to be a constant stream of activity. Is there some other way to see what polkitd and / or these other processes are going?
I would also appreciate any thoughts on how to fix this issue.
