Description Patrick Silva 2021-03-11 15:48:11 UTC
Created attachment 136588 [details]
screenshot before re-login - sensors are working

SUMMARY
I'm not sure if this is related, but systemd startup is enabled on my system.

STEPS TO REPRODUCE
1. have System Monitor widgets on desktop
2. boot your machine
3. start Wayland session
4. logout
5. immediately start Wayland session again

OBSERVED RESULT
Wayland session takes almost 2 minutes to start and when my desktop finally loads, System Monitor sensors are not working. If this problem does not occur, repeat the steps 4 and 5 above, at some point
the System Monitor sensors will fail. Please compare the attached screenshots taken before and after
re-login.

EXPECTED RESULT
System Monitor sensors should always work

Comment 2 Nate Graham 2021-03-11 21:12:48 UTC
Is ksystemstats running?
Comment 3 Patrick Silva 2021-03-11 21:56:19 UTC
yes, ksystemstats is running. 
I have noticed that bith kded5 and plasmashell crash when the sensors stop working.

output of coredumpctl:

Comment 4 Arjen Hiemstra 2021-03-12 10:33:08 UTC
Having the output of "kstatsviewer --list" may help, at least we'd be able to determine if it's ksystemstats failing or something else. Normally speaking ksystemstats should be launched automatically through D-Bus, I wonder if something's going wrong there.

Comment 6 David Edmundson 2021-03-12 11:58:44 UTC
>but systemd startup is enabled on my system.

Could you determine if that makes a difference?
Comment 7 Patrick Silva 2021-03-13 12:12:36 UTC
I can't reproduce the problem with sensors using default startup system.
But plasmashell failed to start on my system after 5 re-logins to Wayland session. I was able to restart plasmashell running "plasmashell --replace" with
krunner but it crashed again every time when my desktop appeared on the screen.
Apparenyly plasmashell was crashing in loop.

I don't remember. I have reproduced the bug again right now, here is the new output after logout and login:

Plasma 5.22 beta after re-login

The problem is a bit different on Plasma 5.22 beta.
Some sensors stop working after re-login, others display weird values.
Please see the attached screenshot.

Comment 15 David Edmundson 2021-09-08 13:17:16 UTC
I checked that we close ksystemstats on logout, which means I'm out of ideas. 

We know it starts when dbus-activated for the test. Which means we're out of any productive clues.

To proceed we will need a dbus-monitor log from login to the bug being visible.
Comment 16 Patrick Silva 2021-09-10 18:09:30 UTC
could anyone provide instructions to get the log requested in
the comment 15 please?
Comment 17 David Edmundson 2021-09-10 22:13:18 UTC
Put

#!/bin/sh
dbus-monitor --pcap > /tmp/dbus-log & 


in /etc/X11/Xsession.d

and make it executable

That will create a file in /tmp/dbus-log 

Not that this file might contain lots of other information, so you might want to just ping me on IRC/whatever and take some screenshots from Bustle filtering ksystemstats

all sensors stopped working

Thank you David. :)
I was able to reproduce after ~10 re-logins to Wayland session. All sensors on desktop stopped working
and Plasma notified about a crash in kde crash handler., as we can see in the screenshot attached to this comment.
