Ubuntu Installation :: Login Loop After Upgrade To 11.04?
Apr 28, 2011
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)
I have a box built by a local shop (AMD Sempron 2400+, 1.? gig RAM). It used to have XP on it, but I replaced that with 9.10. I tried installing 10.04 from CD and encountered the login loop problem many others have experienced. I had it working once when I re-installed 9.10 and then ran the upgrade to 10.04. I got the login loop that had music up to the cymbal crash, which was clipped near the end. I tried the recommendation to switch to a command line terminal, log in, run sudo dpkg-reconfigure gdm, and then restart gdm. It worked, and I should have left well enough alone. However, I thought that it would be cleaner to install from the CD. Unfortunately, when I got to the login screen I only got a blank screen when trying <ctrl><alt><F1> (or <F2, etc). <ctrl><alt><F8> took me back to the login screen where I still encounter the login loop.
I also tried the recommendation to run the install with the F6 parameter nomodset selected. That resulted in loosing the music during the login loop, although I've discovered that sometimes it's simply because the sound is starting out muted.
Another recommendation was to drop into GRUB when first powering up. It took me a while, but I finally found out that one must hold down the shift key on power up to get to GRUB. While that did let me log in to a command line screen, running dpkg-reconfigure gdm did not work, this time. Neither did the idea of editing the GRUB command line to replace quiet splash with nomodeset.
I have read many posts on this forum talking about this problem as it applies to Nvidia or ATI graphics cards. Has anyone had any experience with the VIA video built into a motherboard? Running lshw -C Display while booted from the 9.10 CD says that I have a VIA KM400/KN400/P4M800 [S3 UniChrome] video system.
A recommendation from one of my local PLUG friends was to revert to an earlier video driver that works. Is this possible? Can I take the video driver from 9.10 and use it for 10.04? If so, how do I find it -- what's it called, where is it, what is the 10.04 driver called, and where is it, and can I just change the name of 9.10's driver (if it is different from 10.04's)? If it isn't obvious that I really don't know how this level of things work, let me confess that I don't.
I removed the LXDE and XFCE packages and now when I try to boot into F14 it goes into a loop between the login page and the fedora icon with blue background showing a X over the icon. In other words, it is looping between the login screen and the previous screen. I think I broke it good. Is there anyway to recover from this?
I have installed ubuntu 10.10 on my pc and whenever I login to the desktop it shows the gnome panels, icons, wallpaper and then immediately goes back to the login screen. If I try to login again, it does the same thing all over again but sometimes it works. Is there any way to fix this?
Still learning OS. I had auto login set and noticed at the login screen an option to boot straight to XBMC. Now I cannot boot normally anymore. Walk me through fixing this please. I'm not afraid of the command line.
I have a real issue and need urgent help. I am stuck in a login loop and have looked in several threads in order to find a solution for my issue. I am relatively new to Ubuntu/Linux and do not really know my way around especially when it comes to command prompt. Thus I need someone with patience and who can guide me step by step in order to get to the bottom of the issue and to fix it.
The issue started all of a sudden, no particular reason. I only uninstalled evolution before and then rebooted. The shutting down process got stuck forever and I turn off the PC by holding the power button. Then I attempted to start, the PC boots to the login screen and I select my name and enter the correct password as usual. Then the screen changes for a split of a second to the back command screen and I can see the word crypto or so. Then the screen returns to the login screen and this loops.
I just upgraded to 10.04 Netbook Remix.When I boot, it gets past the splash screen and to the desktop. Before it can load anything, it acts as if it is looping. The wallpaper loads, the screen blinks white and then it loads the wallpaper again... then a white screen, then the wallpaper.I've tried to bring up the terminal and can't do that. I've also rebooted in recovery mode which didn't help.I'm at a loss. I'm on a windoze machine now since I can't get on my netbook.
The login cycles- I already have a problem with mounting something connected with USB (long term minor annoyance, but everything works), but suddenly I cannot log in. When I put my username and password in, the screen flashes black for about half a second, then the login screen re-appears. If I put the wrong password in, I get an authentication error message (as expected) without turning black and then cycling again.
I have no problems going into terminal mode and logging in. I've tried all sorts of suggestions related to this problem- reinstalling ubuntu-desktop, apt-get clean, sudo startx, and the last indicates that x-windows is already running. I've found a couple more things to try, but I'm not too sure how well they'll work. It seems to be connected with x-windows, but I don't know what is causing it. Last night I had a big problem that required reinstalling nautilus (couldn't set up a connection to a remote server), and that problem was fixed- but this developed when I booted this morning.
When I shutdown, I have a black screen with a message of I/O error, loop device... And the computer doesn't complete to shut down. This problem appear since I upgrade to ubuntu 9.10.
I'm using debian etch and I've installed some automatic updates, after that some programs weren't running. So I restarted the pc. Now that the computer boot up normally but when it reaches the login screen it just emit a sound in the pc's speaker,he login screen flickers and is showed another login screen again and again and again (it's automatic). I can logon using the option single-user mode in the grub options, any idead on how can I fix it?
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'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
Fedora 15, fresh install.I changed the wallpaper from default to a solid colour. After switching between gradient to colour the system crashed logged me out and upon logging in it simply runs endlessly accessing my harddisk but never actually loading the desktop.I can kill X and reboot, but it's the same problem waiting for me on restart. I really don't want to re-install or delete users (to put it in context, I just spent 3 days trying to install Fedora because Anaconda doesn't know how to install GRUB correctly).
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?
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 have dell d630- 64bit version So i upgraded to the latest alpha and my system gets stuck at: as far as "Checking battery state" and hangs, i can login to the separate console and run startx but then no window manager is comming up so again, another ubuntu upgrade and another failure
I just did "do-release-upgrade" from ubuntu 9.10 > 10.04 > 10.10 > 11.04 which successful but after a restart, no login console just a blinking underscore. However I still able to login to server using ssh. During the boot I saw this failure "Starting system V runlevel compatibility [fail]".
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
I have a problem to login with the root user from gui (I use Gnome). The root password is ok. Is there a way for me to logon with the user root in gnome?
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.
