Ubuntu :: Unable To Login After Update?
Feb 7, 2010
I have used Ubuntu 9.10 for a few months. I like it because it seems faster than Windows XP or Vista. Nevertheless, it has happened many times that I couldn't log in Ubuntu after an update. I thus had to uninstall Ubuntu from Windows and reinstall a clean copy of Ubuntu again.
1. Is this common to you guys or just me alone?
2. What are the causes?
3.Does Wubi play a role in causing this login problem since I install Ubuntu thru Wubi?
4. What are other solutions in solvng this login problem?

I got a prompt for an update so I went thru with it. I restarted my PC but it wont boot up. I keep getting a black terminal screen which asks me for my log in. But when I put it in, nothing happens. I tried to reinstall gdm but it says its already installed.

I am unable to login following an update, Fedora 13. The screen splashes after crond is loaded. The GUI does not come-up. In text mode i can't login as root or other user accounts except in kernel 1. I can access some files via FTP command. Is the password file corrupt ?

I'm not able to login after system update tonight. whenever I try to login, the screen goes black briefly and it automatically logs off.
I tried both kernel, 2.6.35.6-64.fc14.x86-64 and 2.6.35.6-45.fc14.x86-64, but failed.

This morning (about 7 hours ago) I've updated my Debian testing KDE4 desktop. At load to KDM just fine. Now when I enter password and login it loads for some time then goes black and back to login screen (KDM). The same problem persists with a newly created user.
dash: 0.5.5.1-7.2 -> 0.5.5.1-7.3
firmware-linux-free: 2.6.32-27 -> 2.6.32-28
libxi6: 2:1.3-4 -> 2:1.3-5

I installed Fedora 11 and was trying to setup a Web server for pure LAMP development and wanted to port forward with router so that my webserver can be access from inter net.
Server installation was perfectly fine. I was able to login from the user which I created during the installation. Instead of auto get ip I assigned 192.168.1.100 and then I set a HTML Server port forward.
Where the problem started.
I wanted to configure few users on vsFTPd and I tell you truly there is no place on Google where some one has defined a descent way which any person can understand that we can add some users.
Somewhere I found that Linux normal users can also access ftp if the local_user directive is set YES which i did and I added 3 users.
I wanted that whenever user is connected by vsFTPd returned them /var/www/html directory. Where as vsFTPD was taking them to their home directory (respective to each user)
I was unable to find any way that I can configure vsFTPd to set one default directory path which take every user to www/html directory so that developers can deploy websites.
I notice Gnome GUI offers each user a home directory path so I though why not I gave every new user and existing user /var/www/html as their home directory
which i did... and this is how my Server stop responding to any further login attempts.
FTP is still working fine if I left it open It let the ftp client to connect but Linux server is not allowing login by any user
It gives an error 'Could not update ICEAuthority file /var/www/html//.ICEauthority'
And when i click close then next message is : 'There is problem with the configuration server (/usr/libexec/gconf-sanity-check-2 exited with status 256)'
Is there any way i can undo? Is there any way i can go directly to shell and remove those users and re-add some new users in the default way - I believe if I can add one new user with default directory /home/user I will be able to login
After this is resolve still I will need to search how we can add FTP users and take them to the directory /var/www/html

I upgraded from 10.10 to 11.04 on my Toshiba 32-bit laptop without any problems.Since the upgrade I am starting to have troubles on this machine. Most others are 64-bit and bar an Evolution issue are fine.In this case, 24 hours after the upgrade the machine wanted to do an Update. It would not allow the update until I fixed some broken packages which I did via Synaptics Package Manager. I then Marked All Upgrades and did the update from there.It was fine until I shut down and tried to log in again.I got the Blue Screen of Death!!!!!! I thought only Windows had this!Anyway, I could not log in. The auto login was not working so I used Other which gave me Recovery, entered my UN and PW, and I got the error message:
HTML Code:
Could not update ICEauthority file
I have searched the forum and some other sites, but none of the ideas can I get to work. I can start the machine using a 9.10 CD in the trial mode, but can not download the files suggested or delete the ICEauthority file, etc...

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

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.

When i try to update via update manager it says either "failed" or "hit". It done this on my iMac recently so i took it off there. I've had ubuntu on this laptop many times (Dell xps m1530) and its been fine. I cant even install anything from the repositories. When i try to update via terminal it gets stuck on "gb.archive.ubuntu.com lucid release.gpg" and all the other ones after it.

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.

after initating the update and i enter my pass word, update stops and an error box comes up stating that it is unable to update because there is more than one synaptic manager running, i have restarted and get the same results, and to my knowledge there is nothing else running in the background.

I have been running Ubuntu very well for around a year, until an update caused me to be unable to log in. I didn't want to take the time to find a solution, so I simply installed Mint in a new partition. Unfortunately, a month later Mint started having the same problem. I can't even get my data off of my Ubuntu partition as I encrypted my home folder. I would like to recover that at the very least, but preferably I would like to be able to log in again since I'm stuck with Vista right now.
When the computer starts, the log in screen is an off white with blue highlighting, different from what it usually is. In the upper right hand corner, it says, "Install problem! The configuration defaults for GNOME Power Manager have not been installed correctly. Please contact your computer administrator." I tried package repair in recovery mode to no avail. I can log in to the CLI in recovery mode, but not the GUI.

I am having a problem with the latest update of lucid ubuntu. I was on 10.04 for the longest time but decided to update while I was out doing errands. When I got back the logon screen was made up of blue and gray windows on a completely black background and the mouse and keyboard wouldn't work!
I found that if I unplugged and then replugged my mouse that I could get it working, but not all the options work properly. When you try to close a menu it just stays up, but it isn't there at the same time. Also, the shutdown/restart options don't work along with the physical power button on my computer, I have to remove the battery and power cord to shut it down.
I am currently dual booting ubuntu and windows 7 on my gateway NV59 laptop.

I've updated my ubuntu from 10.10 ==> 11.04. Now I can't login using graphical inerface. System is loading but it stops right before I should see screen with login credentials. When I use ctrl+alt+del it's going to reboot properly, the same when i push the power button it's shutting down. System works fine in failsafex mode so I can assume there's a problem with xserver etc. Using Nvidia 9500GS.

This morning I had the notification that there were 21 updates available, and I selected to install them. The system then notified me that a restart was required and I clicked the restart button. After restarting, the system boots to the GUI screen and I select my name and enter the password. It then plays the login sound, the cursor "swirls" and it cycles back to the login screen. Switching over to another terminal screen I can login from the command line.

I just ran an update of ubuntu 9.04 to 9.10 and now the "startup" splash and the login splash is gone. Instead I see the terminal during bootup and the login prompt is some strange sparse login screen looking like it was taken from some old CDE GUI. What has happened and how do I fix it?
I can also add that while upgrading I chose to let the menu.lst remain untouched which turned out to be a bad mistake. So I added the following lines manually to compensate for my mistake.
But that didn't resolve my problems. I also tried the following without success:

I use ubuntu 10.04 in VirtualBox (upgrated from 09.10), host os is Win7.
3-4 days ago update of ubuntu required restart of Ubuntu (linux kernel was updated).
After 3 days (i.e. yesterday) I restarted the system. I found that flashlib in Chrome became to work unstable, some artefact appeared, and only scrolling down-up in browser allowed to update view of screen. I run update manager. It showed ~88Mb of updates for last 3 days.
After download of updates, apply changes was failed! I faced this first time (!). I remember message like "can not synchronize file /usr/share/..." or something like that.
I restarted ubuntu again. Now I could not login. System hangs after login. No Gnome menu appears etc.
I tried to fix issue using dpkg. I found that some lib (ure) related to OpenOffice was not assigned (version XXX required, but bersion XXXY found). dpkg offered to solve this by some combination. I did so. Then I run dpkg update, and no errors appeared.
Also I updated VirtualBox to version 3.2.4, updated VirualBox Additions via console terminal in ubuntu.
But still I can't fix problem with gdm/gnome.
dpkg-reconfigure gnome-*** did not help for me.
I tried to check logs, but I have not found something "interesting".
At the moment terminal is the only way to login.

After applying an update about two or three days ago, I restarted my system and now I'm getting a black screen at login. I can hear the brief drum sound clip that plays when the login dialog box pops up, but the screen is completely black and I can't see anything. I'm still able to access low graphics mode via the fail-safe option in the recovery mode menu. So far I've tried the following commands in the terminal:
Code:
sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon
sudo apt-get install xserver-xorg-video-ati
sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-

Yesterday, I updated my system with the latest security update and other software updates. Following the update, I am not able to log into the system after restart.As usual, I was prompted with the login page which looks as per normal. I chose my login id and entered my password. It brings me briefly to my desktop showing only my wallpaper (without any upper and bottom taskbars/panels). Then the screen went blank and the login page appeared again.I entered the login id and password, was shown the desktop wallpaper, screen went blank and the login page appeared. This continues over and over and over. After multiple tries and with some luck, I am able to log in as per normal.What seems to be the problem?
1. How do I check the system for errors?
2. How do I check which update has been updated?
3. Is there any way for me to restore to its original state (I migrated from FC10 to FC11 via yum update)?
The only other change apart from the security update is that I installed wine - which has been uninstalled the moment I was able to re-logged in.I attach the details of my grub.conf file below which I hope could be of some useful info.

If someone, like me, updated the shipped kde 4.6 to 4.6.1. using the repo KDE46/11.4 only to find himself stuck at the login screen, try this: From the "type of session" choose "Kde plasma workspace (failsafe session)" and try to login. Once logged in, logout, then choose "Kde plasma workspace" type of session and login again.

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.
