Description Jason Haar 2015-06-09 02:47:15 UTC

Description of problem:

I only installed F22 last week, but have noticed a couple of times a day coming back to the computer to find it hasn't locked like it should, instead showing

Unable to Lock: lock was blocked by an application

Version-Release number of selected component (if applicable):


How reproducible:

20-50% of the times screen locking should be called


Steps to Reproduce:
1. walk away
2. come back
3.

Actual results:


Expected results:


Additional info:

I'm running the standard Gnome install - haven't had the chance to fiddle with cinnamon/etc

syslog shows the following - which may help.

I must agree with the writer of this webpage who had the same problem in F19. It would really help if the error said exactly what was blocking it!

Finally, I marked it urgent because frankly it's a security hole. You can't just vaguely try to lock the screen  - it has to work. This laptop had Ubuntu-14.04 on it before and F20 before that - and neither had this issue.

Six months have passed and this security hole is still present in a fully up-to-date F22 system

I walk away from my desktop for hours and come back to find it never locked...

Just saying...

Comment 2 Fedora End Of Life 2016-07-19 18:54:05 UTC

Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
