Description Christian Stadelmann 2016-08-31 21:43:07 UTC

Description of problem:
Currently, F25 ships gnome-settings-daemon 3.20.1 although F25 ought to be shipping GNOME 3.22. g-s-d 3.21.90 is already released: https://git.gnome.org/browse/gnome-settings-daemon/log/

Version-Release number of selected component (if applicable):
3.20.1-3.fc25.x86_64

How reproducible:
always

Steps to Reproduce:
1. log in into your gnome session

Actual results:
g-s-d is at version 3.20.x
g-s-d is running at 100% CPU on one core.

Expected results:
g-s-d should be at version 3.21.x or 3.22.x
g-s-d should be quiet most of the time

Additional info:
I've reported both issues in this report because after updating g-s-d to 3.21.x this problem might be gone.

I'm currently unable to give reasonable backtraces due to an issue with mirrormanager: https://lists.fedoraproject.org/archives/list/infrastructure@lists.fedoraproject.org/thread/LUDEXSN4GJDTLBAYZEHQV2YARRRV3S43/

Comment 1 Christian Stadelmann 2016-08-31 21:54:09 UTC

Nominating as blocker since
* This bug results in a general system slowdown
* Applications relying on g-s-d break, miss functionality or are rendered useless
* Login takes very long (>10 seconds compared to 2 seconds on F24 on the same machine)
* Logout takes _very_ long (about 30 seconds compared to <1 second on F24 on the same machine)

Citing Beta Release Criteria [1], section "Shutdown, reboot, logout":

Similar to the Alpha criterion for shutting down, shutdown and reboot mechanisms must take storage volumes down cleanly and correctly request a shutdown or reboot from the system firmware. Logging out must return the user to the environment from which they logged in, working as expected. 

logout of 30 seconds is not expected.

I won't mind if it won't make for a Beta blocker, Final blocker or freeze exception would be fine too.

Comment 2 Adam Williamson 2016-09-01 00:46:23 UTC

yeah, I do see g-s-d taking an awful lot of CPU time on my F25 system.

Comment 3 Marek Kašík 2016-09-01 10:35:50 UTC

This could be a duplicate of the bug #1366775. Could you try to downgrade CUPS to 2.1.4 and look whether gnome-settings-daemon is still that busy? Or alternatively install and start cups service.

Comment 4 Christian Stadelmann 2016-09-01 11:23:11 UTC

This is a duplicate, yes. Thanks for the hint on the workaround.

In case you need more information: I'll subscribe to the "first" bug.

I had cups packages removed as far as possible, leaving only cups-pk-helper and cups-libs on my system. Downgrading cups-libs to version 2.1.4 from https://koji.fedoraproject.org/koji/buildinfo?buildID=775779 makes this problem go away.
