Bug 1235681

Same problem here.

This results in lags everywhere. While dragging windows, while typing, ...
Problem seems to be related to NetworkManager.

Try systemctl stop NetworkManager should fix this problem (ofc Internet will not work). Please try this. CPU usage should go away, too.

This happens with Cinnamon only!
Gnome works fine (other DEs, too I think).

Anybody any idea how to fix that?

Yes, I find this only true with Cinnamon

Thanks for your report. Could you try to track down the source of the activity?

Probably the easiest option is to follow https://wiki.ubuntu.com/DebuggingDBus (the system bus part) and look for the most frequent calls to org.freedesktop.PolicyKit1.Authority. )

Alternatively, as root run
> G_MESSAGES_DEBUG=all /usr/lib/polkit-1/polkitd --replac |& tee log
let it run for a while, then press Ctrl-C. Then search the resulting log file for the most frequent instances of
> … is inquiring whether … is authorized for …
(but this might change system behavior because the logging interferes with polkit-pkla-compat, undoing that would require additional steps)

I run this for half an hour and see nothing but:

Successfully changed to user polkitd
20:51:17.594: Loading rules from directory /etc/polkit-1/rules.d
20:51:17.594: Loading rules from directory /usr/share/polkit-1/rules.d

The whole time polkitd is very active and using between 5 and 15 % of CPU.

Sorry, the command is
> G_MESSAGES_DEBUG=all /usr/lib/polkit-1/polkitd --replace |& tee log
(--replace, not --replac); but the output you show suggest that you probably got it to work.

Still, no polkit requests at all? And the system otherwise works fine?!

I guess I will have to spin a VM… I’ll try an ordinary Workstation install + (dnf groupinstall); is there anything special I should know as a first^Wsecond-time Cinnamon user?

I have the same problem with MATE desktop
polkitd is constantly eating 20-50% CPU according "top"

My 10 minutes log:

G_MESSAGES_DEBUG=all /usr/lib/polkit-1/polkitd --replace >/var/tmp/log 2>&1 &
sleep 600 ; kill %1
awk '/is inquiring whether/||/is authorized for/{print$NF}' /var/tmp/log \
 |sort|uniq -c

  22968 org.freedesktop.RealtimeKit1.acquire-high-priority
  31320 org.freedesktop.RealtimeKit1.acquire-real-time

(nothing else)

Thanks, the ~90 requests per second at a few ms per request can easily account for such a load.

So, next step is tracking what causes at least ~50 rtkit calls per second; looking at RPM dependencies. pulseaudio seems to be the only user, but reassigning to rtkit to be sure.
