Screen unlocking fails after switching to console and back
Last modified: 2014-03-31 19:44:31 EDT
Description of problem:
After I lock the screen and switch to console (CTRL+ATL+F1), login as root and
go back (ALT+F7), I type the password and get an error unable to login, auth
subsystem failed and I get instructed to kill kdesktop_lock manually.
Version-Release number of selected component (if applicable):
Note that I have the finger reader, which I use to login. Some relevant files:
[dkovalsk@kovinek ~]$ cat /etc/pam.d/system-auth
# This file is auto-generated.
# User changes will be destroyed the next time authconfig is run.
auth required pam_env.so
auth sufficient pam_thinkfinger.so
auth sufficient pam_unix.so nullok try_first_pass
auth requisite pam_succeed_if.so uid >= 500 quiet
auth required pam_deny.so
account required pam_unix.so
account sufficient pam_localuser.so
account sufficient pam_succeed_if.so uid < 500 quiet
account required pam_permit.so
password requisite pam_cracklib.so try_first_pass retry=3
password sufficient pam_unix.so md5 shadow nullok try_first_pass use_autht
password required pam_deny.so
session optional pam_keyinit.so revoke
session required pam_limits.so
session [success=1 default=ignore] pam_succeed_if.so service in crond quiet
session required pam_unix.so
[dkovalsk@kovinek ~]$ cat /etc/sysconfig/desktop
Steps to Reproduce:
1. Lock session
2. CTRL+ALT+F1, log in as root, echo foo
3. ALT+F7, type your password
I haven't had any other auth issues except with kdesktop_lock.
Let me know if you need more information to diagnose this problem.
funky setup, and steps to reproduce. :)
hopefully, it's only a pam config thing.
Worked perfectly for me with the same setup (also using ThinkPad fingerprint
reader to auth).
Actually for me the problem still persists.
Lukas, can you post your pam config file if there's any difference from mine?
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8. 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bug reports from releases that are no longer maintained.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 WONTFIX if it remains open with a Fedora
'version' of '8'.
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 prior to Fedora 8's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 8 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 please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
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.
The process we are following is described here:
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 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.
Thank you for reporting this bug and we are sorry it could not be fixed.
