Mar 15, 2010
System was fine with :Ubuntu 9.04 (had also installed kde )then....I wanted to try some change to gdm so i downloaded gdm while building it , it asked "PAM" libraries to be installed so i installed PAM ... but ignored the instruction to reinstall SHADOW (library i guess..),Now :on booting system i get login menu but i am not able to login , it says some critical error occured
1) install new copy of UBUNTU and remove old
ps :1) i can log into system through live cd
2) i can use recovery mode boot and log into terminal as root(startx is not working from this terminal..

When I try to login to my Ubuntu Server, I get the following error:
PAM Failure, aborting: Critical error - immediate abort
This occurs when I try to log in locally, or via SSH. I have tried logging in using every account and all create the same error. Ubuntu server edition 11.

yesterday i installed slim login manager on my computer (eee pc 1018p, ubuntu 11.04), and now it cannot get passed the ubuntu loading screen (with orange dots underneath) when booting. i tried booting into recovery mode and that didn't work either. i also left the computer trying to boot overnight and that didn't work.
basically, during this loading screen that should eventually bring you to the login screen, i can alt+tab to see the progress of the load. the progress is stuck on
Is there anything I can do from grub to remove slim?or, is there any way I can access my ubuntu partition and save all my files?

i used to use jaunty earlier but now i use lucid and a small thing that irritates me is that there is no 'login window' in 'system' menu.

I already have two other threads open for a dysfunctional system. Thread 1: Boot hangs at logon sound - no video signal - appears drive is still working [URL]..Thread 2: Where are boot log files and how I can see those? [URL]...Basically both of those are for not able to complete the boot (hanging up in the middle of booting) in Karmic. I had Karmic since it came out but suddenly about two weeks ago just stopped booting. Except for the battery and resetting BIOS, I had checked all the hardware - and all appear to be okay. Following a tip from x1a4, I started looking into logs (admittedly not knowing exactly what I am looking for) and I ran into auth.log. Following is the code. The highlighted part is confusing (to me) and I am wondering if this may cause to stop booting (or completing the boot process) since I was using auto logon. I do not know if there is anything else (logs) you may need, please advise and I will provide those.

I've just started using Debian having previously used Ubuntu. With Ubuntu, under the System->Administration menu I get lots of options (e.g. Network Tools, Printing, Services...) to select from, but with Debian I just get Login Screen. Do I just get the one option because this is the only thing installed, or do I need to do something to enable other admin options?

I recently powered up my netbook... Selected my user log in, entered my password, and after a couple seconds I briefly see what looks to be the console and am returned to the login splash screen... I can Ctrl+Alt+F2 to get to the console and log in... but that is as far as I can get. This is the case for Gnome, Remix, and Remix 2D.
I can sudo apt-get (update, upgrade, etc) as well. It is the right password because if I type in a wrong one it presents an authentication failure dialog box.
How can I fix my log in screen and get to my desktop? I am Currently running 10.04.... waiting to get 10.10

For some reason I am no longer able to log into my Ubuntu 9.10 system. I get to enter the password and it accepts it, starts to log me in but then throws me back to the login screen again without even a glimpse of the desktop. What could be causing this? Everything was working fine yesterday and I haven't made any changes to the OS.

I have an iMac G4 that I installed Jessie on successfully. However, when it boots, one of the last messages is:
[FAILED] Failed to start Load Kernel Modules.
Last line is something along the lines of:
fb: switching to nouveaufb from OFfb NVDA,NVMac
And then the text starts dissolving, and the entire screen cycles through different colors. I presume it is sitting at the graphical login prompt but it's not displaying correctly.
Based on some Google searches, it seems like I should be able to resolve this by editing /etc/modules but I can't get to that point. I have tried to get to a terminal using ctrl-alt-F1 through ctrl-alt-F12. No luck. I tried different yaboot options that were supposed to avoid using the video driver. No luck. How do I get the machine to boot straight to a regular text login instead of the X one?
This machine worked fine running Mac OS X this morning, so I don't think it's the hardware. What I can do.

I am having a problem with my Lucid L. I installed Mac4Lin and when trying to change login window, grub window, splash screen, or even system sounds, I simply don't have the option.
I go to the application like System-Preferences-Sounds and simply don't have the option to change the system sounds, all I have is 5 tabs without that option.
Login widows is the same thing, I can only choose if I want a login sound or not and that's all, I can't even choose to make auto login since it does not give a user as option.
I tryed also with art manager, but the "Install" button is greyed, and startupmanager does not give me any of those options too.

I have installed Ubuntu 11.04 32-bit on my new desktop. After installation all gone well.
The initial upgrades after fresh installation also ran well and I was able to reboot and use the system successfully.This was before three-days.Yesterday night I ran again the Update Manager and installed the available (4-5) updates and then I installed Sun-Java-JDK using Synaptic Package Manager using the packages from the canonical partners.
After installation was done I shut down the system and in the morning when
I restarted the system the login screen is coming up but on entering the login credentials a black screen with some text(unable to see the text) flashes and returns me back to login screen.I tried logging in with both normal and admin type users.But admin type user too encounters the same problem.
I have partitioned my 500GB into 5 partitions and there is sufficient data on each partition.
I assume fresh installation would fix it and the data on logical partitions would be intact but doing this re-installation would require me to install the updates again and do all the settings I did till now again.

I am using rhel 5.3. I am using windows 2003 server 32-bit (the processor is 64 bit. AMD athlon x2). I have installed vmware and installed rhel5.3 64 bit on top of it. Now i am able to login as root from GUI mode (f7 console), but unable to login in text console from f1 to f6. I checked the /etc/securetty. But there was nothing unusual there. I think udev is causing this problem, since google said so. I cant find where the udev.rules file is located that google searches are taking about. How do i enable root login in f1-6 console.

I was having a problem with the keyring asking me for a password after I changed my user password. I googled it and found that since the password changed, I will get asked for the keyring password until I delete ~/.gnome2/keyrings/login.keyring. What happened was that I wasn't paying attention that you had to generate a new keyring password before rebooting.
Now, whenever I try to login via gdm, I get this message: error initiating conversation with authentication system - general failure
How do I get it working again? I can still login from the terminal.

I just installed Fedora 12 and while I was trying to install Skype, there was a system crash and since then I cannot install any other software or cannot even access 'add/remove software'. Whenever I try to install a software or try to open the 'add/remove software' or, 'Software Updates' I get the message
'An internal system error has occured'.
and inside it contains this-
Code:
Traceback (most recent call last):
File "/usr/share/PackageKit/helpers/yum/yumBackend.py", line 2956, in __init__
self.repos.confirm_func = self._repo_gpg_confirm
File "/usr/lib/python2.6/site-packages/yum/__init__.py", line 717, in <lambda>
repos = property(fget=lambda self: self._getRepos(),
File "/usr/lib/python2.6/site-packages/yum/__init__.py", line 496, in _getRepos
self.conf # touch the config class first .....
I tried these using the terminal-
yum clean all
yum metadata
sudo yum clean all
yum clean metadata
and all of these gave me the same result-
Code:
Loaded plugins: presto, refresh-packagekit
Config Error: File contains no section headers.
file: file://///etc/yum.repos.d/skype.repo, line: 1
"su -c 'yum -y install skype' "
Everything else is working fine, but I just can not install or update any more software.
