Ubuntu :: Can't Login After Update
Mar 1, 2011
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 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 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 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:
After loging myself out and pressning ALT+F1/ALT+F7...

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.

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 ?

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.

Recently I upgraded my kernel to 2.6.34.6-47.fc13.x86_64 and then also did an update to 2.6.34.6-47.fc13.x86_64. Both of these kernels I do not get a login dialogue box. I still have the one kernel that works and it is 2.6.33.8-149.fc13.x86_64. The system I am on has a Radeon graphics card, but I don't think the graphics card is the issue since I get the login screen's background, but not the login screen itself. <Later> After messing around with this for a while I came to the conclusion that livna-config-display was messing with the xorg.conf file. Removed it and things seem to be working fine now.

I have a problem with my Fedora 14, only on Fedora 15. Been out of my home for a week, when I arrived home and turned the PC on first thing I made was the update, as usual. But when I reboot or shutdown the PC and when I go to do login, the Fedora get's stuck and doesn't show me the login window to insert my login. Made a clean install and it worked fine, until I made the last updates and it became again, stuck before the login window appears. Is there any update making this? What could be? It must be some update, because when I made the clean install it worked fine, and with the first update also worked fine.

Here's the error I get:
"The configuration has not installed correctly for Gnome power management".
Updated my 11.04 install via the update manager last night. When I turned my computer on today it wouldn't boot into the normal gui desktop. Where my normal login screen usually appears a different login screen appears with my username. I login. Screen flickers black for a few seconds and a page with a ton of text shows up for a fraction of a second ( too short of a time to read a single word). more flickering. Then I am returned to the slightly different login screen once again with the error. I tried booting into failsafeX gui mode. Same issue.

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

This is just a nit, but I have noticed that whenever the kernel is updated, the background picture that I have set up for the login screen seems to be reset to "default_blue". No other setting seems to be disturbed.
After each update, I have to go into Configure Desktop->Login manager and set my background picture again. Why is this happening? Is there a way to fix this?
I am running Suse 11.3, KDE v4.4.4.

After I edit /etc/group and I add a user to groups it didn't belong to, the user will not be able to use it's newly acquired privileges unless it starts a new session. Is there a command to refresh user/group properties in an ongoing session?

I run a CentOS 5.1 using VMServer on XP. From home I can successfully 'cvs login' to my CVS server. But starting 'cvs update', the connection times out.
Netstat shows the connection as established:
# netstat -an | grep 2401
tcp 0 0 192.168.1.35:58651 85.25.xx.xx:2401 ESTABLISHED
CVS server is domain managed with dnsalias service (dyndns.org)
Using the same computer at work (other ISP) I have no problems - cvs update works just fine.
Can I assume that it is not a port/firewall issue, since "cvs login" is successful? Any clues where to start diggin'?

I got a workstation with openSuse 10.3 pre-installed. After I did the Online Update from YaST2 and rebooted the machine as requested by YaST2, the system came to fail starting up an X session.
Below are excerpts of the message appeared on the screen at the end of the boot process. (I transcripted it from the screen by hand.)
Code:
Waiting for mandatory devices: eth1 __NSC__
10 9 8 7 5 4 3 2 1
eth1 devices: Intel Corporation 82573L Gigabit Ethernet Controller
eth1 DHCP4 client (dhcpcd) is running
[Code].....
what is causing the failure of the X session and how to fix the problem? I would be glad if you give me any hints or pointers.

Yesterday I applied the su security patch to my openSuSE 11.2 x86_64 system.After applying the patch, any attempt at su failed, and after rebooting the system earlier this morning any login (root, user, otherwise) fails with a "Permission Denied".Is it possible that the su update somehow messed up my (standard) pam settings?
