Unable To Login

CentOS 12 Comments

Hello,

I have trapped in weird problem. My Setup is CentOS 6.3 Desktop edition x86_64 arch.

My login screen is blinking so frequently that I am unable to see and login into it.

And also I am unable to reinstall the OS because it will take very long time re-setup everything as per my configuration as well as Data.

The problem is as follows:

I have several months ago libgcc-4.4.6.i686.

Today for installing rsyslog, I updated the package libgcc-4.4.7.i686 and libgcc-4.4.7.x86_64. Then thinking

about chances of conflict, I removed libgcc-4.4.7.i686 it has also removed the

cups-libs gmp gnutils gtk2
libstdc++
libtiff peazip

all are i686 type. Then I installed same packages for 64 bit through yum install

Message also said successfully installed. Then I try to open another terminal window but it was suddenly closing

so I thought restart might solve this problem; so I restart the computer.

I am getting normal CentOS login backgroud but getting faster blinking screen.

How should I solve this problem (except formatting the CentOS) as CentOS
is the only OS on that machine.

1. How to login into CentOS now??

2. Which package should I need to install and how ??

Kindly do the needful,

Thank you !!

  • Hello,

    One more thing as per I think I have lost only file which responsible for GUI of the CentOS.

    If anyone has Idea which files I need to get Login and other explorer screen back in action

    that will be a great help to me.

    And I also want to ask that is it possible to install that files from Putty; I have windows on other PC

    so that from terminal there I can install on CentOS machine??

    Waiting for your reply,

    Thanks !!

    I skimmed your other email – a) did you install for 64 bit? b) did I see that you tried picking and choosing from what release? In any case, you need to do yum -y update and update your whole system to current.

    If you’re still having gui problems, you *might* have a driver issue. What video do you have?

    There are no putty files to install on Linux. Putty will bring you in as though you had ssh’d from another *Nix machine.

  • Hello Sir,

    Problem is Appearance of login window. System boots normally; now I will try out your said command.

    I skimmed your other email – a) did you install for 64 bit?

    Yes.

    b) did I see that you tried picking and choosing from what release?

    Release 6.3

    Problem is I have installed Eucalyptus cloud,Snort IDS and now rSyslog ;
    so I am in fear that update

    should not break anything wrt this components so that weird things I
    will face in future.

    BTW, system is working fine before this incident.

    I have not installed any video drivers before this. I tried to install one but it does not work. So I leave it as

    everything was working fine before breakage of libgcc.686 package dependencies (as I remember)

    There are no putty files to install on Linux. Putty will bring you in as

    I am in SSH with this machine from long time. I am asking if I am unable to get GUI then I should try to install files

    from PUTTY terminal or browse files with WinSCP.

    What is your opinion sir??

    Waiting for guidance,

    Thanks!!

    gnome or kde?

    It shouldn’t. And why did you install rsyslog? That’s the default system log package in 6.x. Did you install that from something else?

    You’ll probably have to run whatever snort command once you do a yum update, or I expect you’ll get a lot of false warnings.

    You really, REALLY need to do some reading about *Nix systems. The base install installs video drivers; if you add a desktop install, it will install its best guess at drivers – they’re already there. Unless you’ve got multiple monitors, in which case you may well have trouble, then the gui should just work.

    Wait – how are you trying to log in, from the console, or remotely?

  • Hello Sir, sorry for late reply.

    Gnome.

    It shouldn’t. And why did you install rsyslog? That’s the default system

    I think sir you are talking abt CentOS 6.4 becoz in CentOS 6.3 there is upto 5.8.10.

    Did you install that from something else?
    I am installing from source version 7.2.6 because of which this all mess.

    You’ll probably have to run whatever snort command once you do a yum

    I will try for it.

    I will first try out your instructions ; if that works. No remote no console.

    If not, then I will try to login from Putty – windows client. And sir,

    would you please more focus on *nix systems?? any link??

    And could you briefly address me what is actual mess around here??

    Waiting for reply,

    Thanks !!

    You. Do. Not. Understand. What. I. Am. Saying. You need to stop and THINK
    while you’re reading. rsyslog is the default syslog in ALL VERSIONS of CentOS 6.

    I don’t think I’ll respond again. I feel as though you do *NOT* understand linux (or any other version of Unix, usually referred to as *Nix). Go read the FAQ from the CentOS website. Go read wikipedia.

    I’m tired of making suggestions, and you don’t have a clue as to what I’m asking or suggesting.

    I’m at work, for which I am a senior person, and get paid for that. I feel like I’m wasting time trying to help you.

    Try googling for answers, before you post, or if you don’t understand some of the suggestions.

  • Hello Mark Sir,

    Sorry if you feel bad due to my foolishness and inadequate knowledge.

    My actual problem is that my setup is at college and due to internet connectivity

    problems as well as college hours are over, I am responding from home.

    So as per your instructions I will again go thoroughly through your replies.

    And I hope that I won’t try to disturb you.

    Sorry for my foolishness,

    Thanks for your help !!

    >>>> One more thing as per I think I have lost only file which responsible

    Yes Sir got it.Now I understand no need to reinstall rsyslog just use default one.
    How foolish I am !!

  • Hello,

    My X windows system is not working

    So, Mark sir has recommended following steps that what I understand:

    1 Press ctrl+alt+f2

    2. Then run these commands

    yum groupinstall basic-desktop desktop-platform

    >> install installs video drivers; if you add a desktop install, it will
    >> install its best guess at drivers – they’re already there. Unless you’ve
    >> got multiple monitors, in which case you may well have trouble, then the
    >> gui should just work.

    3. After that I should perform

    yum -y update

    4. Then I should run command for snorts.

    If anyone finds any lacunae please guide

    Thanks !!

  • Hello,

    I have done following steps:

    Press Ctrl+Alt+F2

    By root login, I entered following command :

    yum groupinstall basic-desktop desktop-platform x11 fonts

    Then I reboot system; only blank screen appears ; not even cursor.

    Then I tried this :

    yum groupinstall -y ‘ X Windows System’

    yum groupinstall -y ‘ Desktop ‘

    Then I open */etc/inittab* via text editor and change following line:

    id:3:initdefault:

    To:

    id:5:initdefault:

    Then give command to start the GUI:

    $ init 5
    but screen stop responding after giving message ” Starting jexec services “.

    After that I reboot system, Then I run.

    $ startx

    It has loaded some packages but failed to load and stop there.

    Then I tried this gnome-session, gnome-panel and gnome-applets.

    It has said everything is installed.

    After this, I tried this:

    yum -y groupinstall “X Window System” “Desktop” “Fonts” “General Purpose Desktop”

    upto 83 MB installation Then I reboot and entered startx

    it has given following error and stopped

    Loading extension GLX
    FATAL: Module fbcon not found.
    [dix] Could not init font path element catalogue:/etc/X11/fontpath.d, removing from list!
    [dix] Could not init font path element built-ins, removing from list!

    Fatal server error: could not open default font ‘fixed’
    (EE) Please consult the CentOS support at http://wiki.CentOS.org/Documentation for help.
    (EE) Please also check the log file at “/var/log/Xorg.0.log” for additional information.

    [89.274] (EE)
    [89.274] (II) AIGLX: Suspending AIGLX clients for VT switch

    Now as the last measure, I have run the

    yum -y update

    today itself. 243 MB, will get complete tomorrow (as per I hope).

    I have google for this but not find confirm solution.

    Am I missing something; please help ??

    Seeking for guidance,

    Thank you !!!

    It is virtually impossible to deduce from your description what’s wrong with your machine. You should find someone in your vicinity who knows Linux and can have a direct look.

  • You should not have removed the i686 packages. The packaging system ensures that there are no conflicts. I suggest that you reinstall them. It may be that there is no need of them, but second-guessing the packaging system is never a good idea, unless you know *exactly* what you are doing.

    Cheers,

    Cliff

  • Thanks to especially Mark Sir.

    After *yum -y update* system is now enjoying GUI !!

    One thing to mention is that my system processing also increases considerably !!

    Thanks again to All !!
