Description Robin Rainton 2016-01-24 11:04:24 UTC

Description of problem:

Login from GDM is very slow when connected to network with slow/no Internet connectivity.


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

Linux x220 4.3.3-300.fc23.x86_64 #1 SMP Tue Jan 5 23:31:01 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
gdm-3.18.2-1.fc23.x86_64

How reproducible:

100%


Steps to Reproduce:
1. Be in the vicinity of WiFi network with poor Internet connectivity. On my laptop, for example, it will connect to any hotspot in the history list, but some of these have restricted, slow, or no Internet activity.
2. Login

Actual results:

Screen blanks (goes grey) and mouse cursor appears in step just prior to showing desktop. This stays for perhaps 20-30 seconds before desktop appears.


Expected results:

Login should be almost instant.

Additional info:

It's clear that on login some part of the process requests information from the Internet, but only when connected to a network.

If WiFi hardware is disabled then this problem does not occur.

Perhaps it is Gnome Shell causing this delay. Happy to run some debugging to find the issue if necessary.

Comment 1 Fedora End Of Life 2016-11-24 15:08:44 UTC

This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '23'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 23 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 2 Fedora End Of Life 2016-12-20 18:07:06 UTC

Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 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no longer maintained, which means that it will not receive any further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.
