Thread: GUI "Authentication failed" 11.0

  1. #1

    Default GUI "Authentication failed" 11.0

    I am on openSUSE 11.0 with kernel 2.6.27.7-9-pae

    System has been working well for many months. Today I boot and attempts to login through the GUI as any user (including root) fail, presenting the message:

    Authentication failed

    However, the machine is running. If I switch to a console using Alt-F1 I can login as a user and su to root. Also, samba is working and a Windows machine can connect to shares as it has for some time.

    I have been looking around the net for some way that the GUI might have been configured for a different authentication, such as LDAP, that I am not running. There are many places to find the GUI tools described, but I cannot find one that describes command line configuration.

    Do you think this authentication reconfiguration might be the problem? If so, how can I tell and how can I change it?

    What has changed most recently is that yesterday I installed the Google Chrome browser. Appeared to install correctly and was working.

    Any ideas or suggestions? Thanks.

    If you login as user can you then do: startx

    When I run 'startx' there is a message...

    Code:
    Fatal server error:
    Server is already active for display 0
        If this server is no longer running, remoe /tmp/.X0-lock
        and start again.
    Since the GUI login window is still up, I am assuming that this is the X instance that is running. Is that correct?

    That is telling you that you already have a X session logged in
    Do you have auto login enabled? If you do:
    Reboot to level 3 and start yast and disable auto-login
    Boot to Level 3, then Yast and More.... - openSUSE Forums

    Or reboot to level 3, login as user, then do: init 5
    then: startx

    Many thanks for the detailed description to get into yast. Reminds me of the 24x80 days.

    Auto Login was -NOT- enabled.

    Using 'ps -ef' shows that /usr/bin/X is running as root on tty7.

    Any other ideas or suggestions?

    I'm out of ideas really.
    You know 11.0 support ends very soon?

    How many user accounts do you have? (You should never login as root BTW)

    Is there anyone else in the forum that might have a suggestion?

    No, I did not know 11.0 support ends soon.

    There are 8-10 user accounts. Probably 20+ application accounts. Yes, I know not to login as root. That's why I said that I logged in as a user, then did an su to root.

    At this point, I would login as anything that worked.

    If nothing can be done, I might give Ubuntu a spin, but I would rather be using openSUSE.

    If you would rather be using openSUSE - why use Ub*?

    Support ends June 30th for 11.0

    That's a heck of a lot of user accounts
    IMO: Time to backup what you really need

    Format it all

    Install 11.2

    1. what happens if you, at the first green screen select something
    other than the default, like maybe "failsafe" or one of the
    non-default kernels?

    2. what happens if you, at the first green screen type 3 (which will
    appear then on the line for kernel parameters) and then press the
    "enter" key? it should dump you at a command line in runlevel 3 (no X
    running anywhere), where you might be able to log in, issue a init 5
    and be presented with a GUI login screen..

    or, at the runlevel 3 screen log in as yourself and give startx (what
    happens?)

    now, we all know that mommy's vase didn't jump off of the table by
    itself while while little Paula was not touching it....so, tell us
    what all happened between (post one's) "System has been working well
    for many months." and "Today I boot and..."

    that is, what config files might have been changed? what updates were
    applied? what was installed? what was 'tuned', 'improved',
    'customized' and/or etc? who else had access and could be the one who
    "didn't do nothing" it just jumped off the table?

    do you know the date of your "Today" in post one of this thread? can
    you search /var/log/messages (and others) for evidence that somewhere
    between "many months" and "Today" someone did something as root,
    somewhere??

    and, once know how the error was introduced into the system: is it
    possible to back out, and get back to the workig system?

    if not, why not just go ahead and restore the system from the backup
    nearest the date of "Today"?

    *or* maybe it _did_ jump off the table by itself: that is, maybe you
    have some corrupt RAM that wrote a mistake to your hard drive and THAT
    is the change that occurred! or, maybe your hard disk is flaky and a
    few bits in exactly the wrong place flopped from one to zero, or vice
    versa..

    in any event, since there are hundreds of thousands of openSUSE users
    who have not had your unusual problem, you will get no relief by
    switching to Ubuntu...because there you will find the same hardware
    problem and the same keyboard operator not doing nothing to cause
    problems...
