Ubuntu Installation :: After Upgrade To 11.04 Cannot Login Any More
May 5, 2011
i've created a completely new user, so config files for fluxbox/unity/gnome cannot be the problem. when i try to login with this user in gdm, the screen goes black for a few seconds and gdm displays again.
tried:
- new user without any gnome/unity/fluxbox config
- tried "ubuntu", "ubuntu-classic", "ubuntu-classic without effects", and "ubuntu-classic safe mode"
- did aptitude purge gdm & installed it again
- nvidia module is loaded properly
- no errors in /var/log/Xorg.0.log
- login with NXCLIENT on this server works perfectly fine

I've just ran the upgrade from 9.10 to 10.04 via the online update manager. It rebooted and now hangs at the text screen before any graphical login screen appears. The last line on screen appears to show a failure to connect to a cifs share on my other windows computer.
I've tried to select the recovery menu, which then appears but the keyboard does not allow any of the options to be selected with the arrow keys or any other I tried, I've tried a ps2 keyboard and that doesn't allow any selections either. But it is possible to use ctrl-alt-del to reboot from this non responsive menu.

I just upgraded to 10.04 from 9.04 and I cannot log in to the machine. I tried launching the on-screen keyboard but it just flashes and disappears. Anyone else having this issue?I also tried attaching a different USB keyboard, but that didn't work either.

I upgrade my system from 9.04 to 10.04, then when booting, I get the purple wallpaper and mouse, but nothing else, No login menu. I can hopefully connect to my system with ssh from another machine, I update everything, upgrade, etc etc, try to boot on recovery mode, and clean packages and so one...Nothing happens, still no login menu.

Recently I decided to upgrade my 10.04 installation the lazy way, by clicking the upgrade button instead of a clean install (32bit). Now, I can only get into Ubuntu with the recovery mode. If I let the system boot the normal way, I end up at the login screen where I (correctly) enter my password and then nothing else happens. I can move the mouse, the clock ticks on, and I can even use the restart button, etc. But the login screen stays gray and does nothing else, so no desktop. With recovery-mode I can use the failsafeX option to get into the desktop, everything works fine there. And even though it calls it a low-graphics environment or so, everything looks normal, its even my native resolution of 1440x900.
My first idea was some driver issue for my Ati Radeon HD 2600 Mobility card, so I looked into that. I've checked/done the following:
- Installed the drivers manually (downloaded from AMD)
- Uninstalled those drivers
- Used aptitude to remove any fglrx things
- Installed Jockey
- Installed the drivers with Jockey
- Removed the drivers with Jockey (Ive read this is the cleanest option)
- "no drivers" at this point
- Use generic/default X config, make specific X config (both from the failsafe X boot thing)
Nothing worked at all, booting still only works with recovery option and then the low graphics mode. Otherwise, it will just "hang" on the login part. When I boot first recovery mode, and then pick the resume option, I'll see some errors near the end of the booting process.
I've seen 2 errors which might be related to my issue:
- "Unable to allocate crypto cipher with name [ecb(aes)]" (home is encrypted, and accessible with safe boot)
- BUG: CPU#1 stuck for 61s!
Now, the second error seems to "match" with hanging at login. I login, something is stuck and churns the CPU... and never gets unstuck, so login just hangs there. However, I can't find any information related to that stuck CPU thing. Only changing PIDs and other numbers/stack traces, no processname or any other name to work with. So I'm at a loss here.
Big dump of possibly interesting part of kern.log:
Code:
Nov 26 20:31:25 lexmortis-laptop kernel: [44.572381] BUG: unable to handle kernel NULL pointer dereference at 00000021
Nov 26 20:31:25 lexmortis-laptop kernel: [44.572386] IP: [<c027c1b0>] sysfs_delete_link+0x30/0x70
Nov 26 20:31:25 lexmortis-laptop kernel: [44.572397] *pdpt = 0000000035f29001 *pde = 0000000000000000 .....
Despite that with low graphics mode everything works, it seems to be a non-graphical issue here (stuck CPU on some process?). Unless I missed another option I can test for the graphics / drivers. ow I could find more info on stuck CPUs during boot?

I just finished the upgrade of 10.10 to 11.04, restarted and now i can't login anymore, i'm stuck in an endless login loop.
1) Boot
2) Xorg starts
3) I see my user, login
4) Screen goes black like it's loading
5) Loop back to login
It's not a password issue, i can login in command line It's not a profile issue cause i tried creating a new user from the command line and it still loops. I looks briefly at the /var/log/... but i couldn't find anything relevant,respond ASAP this is my work PC.
I thought it would be simple since it's a very simple a relatively new machine (2months ago)

Right after I type in my username and password and hear the usual login sound I have to wait about 15 to 20 seconds to get the X desktop. The system load average monitor is at its max and starts to become lower.If I log out and in again I dont get that delay. It only happens with logging in after a reboot/power on.I tried to open a console (Ctrl+Alt+F1) before I log in, move back to X and login then jump to console and use htop to see what's eating up my resources during that time with no luck. Everything seems to be normal.

I had a working workstation with Karmic. Then I decided to upgrade to Lucid. Bad move, it turns out.First the upgrade crashed. Just stopped doing something for hours on end, and I eventually had to reboot. After that, I had to apply lots of apt-get and dpkg love to get the machine to book. Now, I *think* I have a Lucid system, at last. Only that it doesn't work where the Karmic system used to...Our setup uses kerberos and autofs. To begin with, the upgrade lost my /etc/krb5.keytab (making it impossible to log in), but that can be easily replaced.Now, I can log in, but my home directory doesn't get mounted. In /var/log/auth.log, I get this:
Code:
Jun 23 11:13:58 pc13477 gdm-session-worker[1801]: pam_krb5(gdm:auth): pam_sm_authenticate: entry (0x0)
Jun 23 11:13:58 pc13477 gdm-session-worker[1801]: pam_krb5(gdm:auth): (user hans) attempting authentication

I did an upgrade on my system yesterday. After the completion of the upgrade on restarting the system the computer enters tty1 mode straight without giving me the GUI login screen making it difficult for me to work. The question does now is what could have caused this to happen ? Have i gottten something wrong somewhere?
To switch to tty7 mode i hit the key crtl+alt+7 but it gives an error message about an unknown user even after login in with my username and password on tty1. Start the computer on recovery mode and selected the option correcting broken packages and it produced a result requiring me to download some new packages. I have a huawei e1550 modem which i use to browse in Nigeria. I want to know how i can connect to the internet on the tty1 after insertion of the modem so i can download the necessary packages it requested on issuing dpkg command

Today I was prompted to upgrade to Ubuntu 9.1, and then again to 10.04
Doing these upgrades wreaked havoc on my system. I have been able to fix most of the problems that were caused but I am having trouble finding information on the following:
When I boot up the system and after passing the GRUB loader, the system freezes up at the login screen and I have to power down.
If I hit ESC at the GRUB screen and choose Kernel 2.6.32-25-generic (recovery mode) and then choose "failsafe graphic mode", then I am able to log in to GNOME as normal.

I just upgraded from 9.10 to 10.04 beta and now I get the login screen - but after logging in, all I get is a blank screen with a black bar on top showing just the time on the top right hand corner. If I CTRL+ALT+F1 and reboot using the command line, it restarts showing mythbuntu on shutdown. Im have nVidia GEForce 8600 - is this due the X crashing? I tried all these - no change
Code:
sudo dpkg --configure -a
sudo apt-get install --reinstall ubuntu-desktop
sudo apt-get install -f

About a week ago I used preupgrade to make the transition F14 -> F15 on a x86_64 workstation.
The system has been fully updated ever since, but I'm still not able to login either with KDE or Gnome. With KDE, the login process freezes before completion, whereas with Gnome I get the "wallpaper" behaviour reported here: [URL]
Funny though, I can login in the KDE failsafe session.
I could find no other thread reporting this problem and am at a loss on how to start diagnosing the problem. If anyone out there has any suggestion, I'd welcome it...
what's the difference between a "regular" KDE session and the failsafe one? They both look & feel the same to me...

Just before Lucid was released, I installed karmic on a vanilla VM in 64-bit mode, and all was good. Did a desktop setup and afterwards installed Eclipse, and I was happy: A new system for coding on-the-go! Now, after upgrading to Lucid with do-release-upgrade -d, I can no longer enter my password on X login. The keyboard just doesn't work for some reason. When I enable the onscreen keyboard, and click my password, I can login. The strange thing is that my keyboard works like a charm after I've logged into my X session?

I upgraded to fedora 10 using yum but i have a problem, the installation went fine and after rebooting i got a login screen. I typed in my user name and password and after a second it returns to the login screen. Im sure the username and password are correct. If i type in another password i get an error message. So how can i log in?
This is what i did to upgrade to Fc10:
Code:
Then i got an upgrade wizzard and selected Fedora 10 and than reboot.
In the grub menu only one kernel is present which is the Fc10 so couldn't use the old one.
I've tried to edit the kernel with single for single user that works gives me a command line but im just not experienced enough to figure out how i can use the command line to login.

My system is Dell 4300S with 1.4 GHz Pentium processor, recently upgraded to 1 GB RAM,120 GB WDC1200JB hard drive Sony DRU-720A DVD/RW drive, ATT plugandshare wireless adapter with Atheros AR5001X chip, ATI Rage 128 Pro Ultra TF video card, and Actiontec V90, and 56KFlex modem (Agere System Venus). I attempted to use preupgrade to upgrade from Fedora 12 to 14 using wireless connection. It seems, that upgrade finished successfully, except I am not unable to get to a GDM login. I updated SElinux to selinux-policy-3.9.7-10 and selinux-policy-targeted-3.9.7-10, and touch /.autorelabel overnight, I was able to login using GDM once. And that is all. After I boot, after Ctrl+Alt+F4, I can login to terminal.

I was using Fedora 11 for the past few months. It was working fine. I upgraded yesterday to Fedora 12 and now every time I boot up, the fedora logo screen comes up, the "f" is filled up and after that the screen goes hazy. I was expecting the login screen but nothing comes - the system freezes sort of.

I keep getting the following msg as I try to upgrade from 10.04 -> 10.10 ... "Could not calculate the upgrade An unresolvable problem occurred while calculating the upgrade: E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. This can be caused by:
* Upgrading to a pre-release version of Ubuntu
* Running the current pre-release version of Ubuntu
* Unofficial software packages not provided by Ubuntu
If none of this applies, then please report this bug against the 'update-manager' package and include the files in /var/log/dist-upgrade/ in the bug report." I don't think any of the issues above apply - can anyone offer advice on how to get around or "force " the upgrade

I have used Ubuntu since 7-4; I now have 10.4. However, in the last week I have been taken to the login screen three times. This could be potentially calamitous. Ctrl+Alt +Backspace have by default been disable since 9-4. There is no way I am pressing atl+Prtscr +K. I wonder if there is a new zap command in 10.4, and if so, how to disable it. I have never found the need to go back back to the login window. I am generally using the command line when doing this.

I have just did an upgrade from 9.04 to 9.10. I am planning to go to 10.04 . After the upgrade everything was ok but I noticed the GRUB was still legacy. So I updated my GRUB to GRUB2. Now when I boot, after entering my logon-id and password, it just brings me back to the login-id screen (to logon on). Any indication of what is wrong and how I should fix this ?
I have no encryptions. [added comments] Currently reading thread about login loop bug with 9.10 Followed instructions about possible missing pre-release update but even if it did do updates, I am still login screen looping. Doing additional researches until someone answers with the fix.
did :
CTRL + ALT + F1 switch to one virtual console
sudo service gdm stop

I installed Xubuntu 9.04 on an old Acer Aspire 1200 (PIII, 256Mb of RAM). The install went ok and I was greeted with a login screen at the beginning of every new session.
I later upgraded to Xubuntu 9.10 and since then I've lost the login screen. All I'm left with in the shell (tty1) for which I have to put in my login and password before I can do anything. Typing startx at the prompt starts the desktop.
how I should reinstall GDM or its XFCE equivalent?

I have recently upgraded to ubuntu 10.04 on a machine which I installed the kubuntu-desktop package onto. After the installation I tried to login to a KDE session and my password is accepted. The login screen disappears before the loading splash screen for KDE appears, however this only stays on the screen for a few seconds before the login screen appears again and the drumbeat sound is played (as if you had just turned it on).
Note that GRUB works fine.
UPD (17:48:10 4/06/2010) I have re-installed plasma-desktop, kubuntu-desktop and kdemain packages and this has only caused a longer delay before the login screen is displayed again.
Please could somebody send me in the right direction to get this fixed. I have attached kdm.log.1 as a txt file as this may help diagnose some errors.

I installed 10.04 on my pc. I also have 9.08 and XP installed. Both work. The 10.04 gui login screen displays and asks for the password. I enter the password. The screen goes blank but after a few seconds the gui login box re appears and again asks for a login. I rebooted into the TTY, created a new user, checked the new user was in in /etc/passwd and that I could get into the new user's account. When I rebooted into the gui the new user was there and I entered the password but again I just got back to the gui login window. The pc I am using is at least 5 years old. I have tried startx and I do get the gui background but no controls are displayed. I am using 32 bit 10.04. Using the TTY I have uploaded all the current fixes.

I did a upgrade to 10.04 on my server. Then after a reboot I was unable to remotely get into server. Upon connecting the monitor I am greeted with the purple 10.04 boot screen with this text at the bottom:
Code:
The disk drive for /dev/mapper/cryptswap1 is not ready yet or not present
Continue to wait; or Press S to skip mounting or M for manual recovery
Now I did some googling and the results I came across involved a encrypted drive which I have never even tried to setup. Now if I choose a manual recovery I am dropped to cli which from there I can start networking then ssh into the system and run updates, ping other machines, etc. But again this is meant to be a remote access server so everytime I reboot I cant just hit the M key let alone run service networking start! So I commented out the swap entry's in both my /etc/crypttab and /etc/fstab...now I cannot even get to terminal as I could before...now it just loops with no errors!
