Ubuntu :: GDM Login Starts And Then Goes Back To Login
Feb 7, 2011
I just upgraded from 10.04 to 10.10 this morning and after the upgrade I can't log in via GDM. If I log in it seems to work and the screen goes black, but then it goes right back to the login screen.I can't figure out what is throwing the signal, but the interesting thing is that if I stop GDM and log in on the console, I can run startx and my session runs fine (I'm typing this message from firefox). Any ideas on how to determine what is throwing the signal? I tried poking around in /var/log but I can't find anything that seems relevant.
I don't what happened but yesterday I was working normally and then I shutdown the computer, today when I opened ubuntu it took me to tyy1 login screen, I entered my username and password then it took me to the normal login screen with the login drums sound and it wrote on my account (logged in) so I clicked it and I entered my password again and then I got to my ubuntu so what went wrong and how to fix it also I noticed that a new terminal in system tools occurred called Kernel (I didn't add it)
I'm using ubuntu 10.10 on Dell inspiron 1520 with Nvidia 8600GT and 3GB RAM
Important: this happened after update to generic-headers-24
My computer was working this morning and both hard drives were working fine, then all of a sudden for about two hours I was stuck with this "problem", then after fumbling and moving and stablizing things, then Windows works? See below for details. I've finally reinstalled both hard drives, but the one with the Linux partition doesn't work: it says nothing is discovered on the disk. I can't login at the LUKS login after grub starts, therefore I can't get into Linux, but Windows works?! I used to be able to go directly into Grub when the computer starts, I forgot how to do that but it doesn't matter. If you need details I'd be glad to provide them. I just wondered why Linux doesn't work, but Windows does. I have Linux & Windows on two different separate hard drives
I was helping a friend of mine upgrade his system from 9.10 to 10.04. The upgrade went okay and he was able to use Lucid last night.
He has a dual boot with Windows 7, which was broken during the upgrade. I was able to help him fix that, using the instructions at [URL]
So the Grub issue is not the problem. However, after fixing his Grub install, he now cannot log into Ubuntu.
He selects the current kernel from the Grub menu, and the system starts up as expected. The splash screen that generally has the login box on it comes up - but no login box with user names and prompt for password never displays.
He can press CTRL-ALT-F2 and login from a terminal, but has no option to log into GDM.
I've gone through the usual dpkg-reconfigure gdm and had him reboot. Still no luck.
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
When I try to login with my username, the one I created when I installed the OS, it seems to try to login but almost immediately kicks back to the login screen. No authentication error it just seems to just logout? The only change I made since last successful login was to add ". .alias" to the .profile file - the only entries in the .alias file are comments and "alias" commands. I have one other username but it is not in the sudo's list of users so I can not change anything in the master login.
Every account every option I try. when I login, it just cycles back to the login screen. I have attempted to do a repair install, but to no avail. it happens when I try to boot normally or if I boot into failsafe.
The graphical login screen is loaded just fine. Though very shortly after (a moment after the loading screen could be seen) it crashes back to the graphical login. And that happens no matter what wm I'm trying - gnome, kde3, kde4, e16, e17, even twm.
It happened after the logout after a zypper up yesterday morning. Looking through the list of what packages were upgraded (two machines, both last zypper up'ed last Sunday, checked on the second one after the problem with the first one), the only packages which might be responsible are kwin or qt4.
The graphics card seems to be fine (NVidia 9600), as it happens whether or not I use nv or the propietary driver. Also tried reinstalling it from the repo as well as using the binary blob from NVidia. Has been tested on Windows and games are running fine there, so it shouldn't be the card.
What is strange, is that when calling upon sax2 -r from runlevel three, the initial screen loads nicely, but sax2 crashes back to the cli once one presses 'Change Configuration'. No error messages are being printed.
Any pointers on how I can narrow down the cause (and get it fixed)?
My last setup (years ago) ran fluxbox so because it was familiar I installed it as a secondary to xfce right off the bat. I download a lot of different stuff because I like to try out all the apps I can find but somewhere I broke something. I can still run fluxbox fine, but nither the Xubuntu nor Xfce sessions will run now. Last thing I remember changing was pulse audio(removed it for an experiment I was trying with jack audio), not sure if it is connected but when I try to login to xfce the screen goes black, flickers a few times then it brings me back to the login screen.
I tried failsafe but everytime I do my monitor gives me a "frequency out of range" error. I tried purging and reinstalling xubuntu desktop and xfce settings but I am thinking its my xorg config. My laptop is a Toshiba satellite M305D-s4830 with ATI Radeon 3100 mobile graphics card and I am running Xubuntu 10.10. Unfortunately I also broke the screen, so right now I am stuck with an external monitor till I get a new one.
I would like to post my problems here with Fedora 11 regarding that I am using Dell inspiron 1525, Dual core-N series. I have got two problems:
First;- After I updated my system, I have experienced a a login problem , which is each time I try to login and insert my password correctly it seems that it will login but it comes back to the same login screen as if I did not do anything, but after too many times it works.
Second: I read some posts in a website that talks about configuring the RPM fusion "Repo" and I did all the steps posted there , but after that whenever I try to update or download anything through terminal.... it appears the following:
I have installed VirtualBox and setup a Windows Vista host, initially with a .vdi of 10gb. That filled up quickly, so I added another 20gb secondary partition, after first trying to allocate a .vdi to a SCSI controller. Configured the drive in Windows (Computer Management), and all seemed ok. I shutdown VB, and rebooted my Linux host (openSuse 11.3). Now I keep bouncing back to the login screen, and can't login to Linux KDE, but can login to a console.I do have the following info:
I did see a message before, that I don't see anymore, that said it could not start NFS services due to missing entry in fstab. Another I'm seeing now is it couldn't start the avahi-daemon, no space left on device. This is odd, since I have a 200GB drive, with half of it left, only max 30GB set to VB. Here's my df -k output:
/dev/sda6 Use% is 100% devtmpfs Use% is 1% tmpfs Use% is 1% /dev/sda7 Use% is 46%
So root "/" is mounted on /dev/sda6, which looks like it could be a problem, but why would this suddenly be a problem after working with VirtualBox? Could this be a matter of just freeing up space on /dev/sda6? Like the /tmp folder that's under "/"?
just uninstalled and reinstalled the alsa-base linux-sound and alsa-utils packages and reinstalled gdm and ubuntu desktop after uninstalling the packages to try and get sound working again. Now unfortunately GDM is starting but there is no login on the screen. How can I solve this problem without losing all settings/data?
New to Linux in the last year, used Debian Wheezy off and on for a time - trying to build a system up from a minimum net-install, just to learn more about it.
I have a niggling little problem - either of understanding or configuration. I started with the min install and installed X using apt-get or aptitude. Then installed JWM, which I would start from the console via startx. I really liked this setup, since it was simple and I knew what was going on. This was all on Wheezy.
After the upgrade to Jessie (via dist-upgrade), I would get messages popping up "on top of" the console login when I booted. Stuff like "b43-loading firmware …" would pop up on screen while I was typing my login/password. This was kind of disconcerting (seemed like something must be misconfigured) but didn't effect functionality at all.
Eventually I decided to try a display manager, since that would (I thought) avoid the whole console login process and thus the weird overlapping messages. I installed LightDM through aptitude and it works great, but the console login is still displayed first (briefly, maybe 3-4 seconds) before the LightDM greeter takes over the screen.
It is there just long enough to confuse the unwary, who start typing their login name only to have the screen replaced by the LightDM login screen and have to start over. Obviously this isn't a big deal (everything works fine), but since the whole point of this project was to understand, I'm very curious if this is normal behavior (videos I've seen of folks installing Debian seem to show boot messages jumping straight to the DM without showing:
Debian GNU/Linux … tty1 debian login:
or if I've neglected to configure something that would allow boot directly into LightDM or hide the text console while LightDM loads or … something.
I'm running Ubuntu 11.04, using an nVidia graphics card. I have my TV hooked up to my computer and acting as a second monitor, using the Twinview option with the gpu. My monitor is set as the primary display, with the TV as secondary.
The problem I'm having is that when I turn my computer on, the main display is black, and all the load up information is output to the second display. Then, when I get to the log in screen, it is also on the second display.
I've restarted a server a couple times, and during the boot process pings respond when it brings up eth0, but then when i get to the command line login screen, the pings die. once i log in and do a ./network start the pings respond again, so i'm guessing its dying or not set to start automatically maybe? What should I check?
I'm having a problem with my screen in opensuse 11.4.Everything is ok until the login screen. After the login, when kde starts, the screen gets inverted, rotating 180 grades. The system performance is very slow when this happens. I tried to disable the KMS to use the default system driver, what worked. But with this option, I don't have the performance and resolution available with KMS.
I did a clean install of xubuntu 9.10. I set up an account for my wife on it and now everytime I try to login under my own it keeps going back to the login screen. Sometimes twice last night I had to log in 4 times before it went to the desktop. I have played with some live CD's of ubuntu and xubuntu, but this is the first full install I have done. Before I set up the wife account, I could login first time. Should I try and reinstall and hope for the best or is there something in terminal that could be done?
That's a picture of my ubuntu 9.1 64bit login screen. The background image I changed myself months after this problem started, so I'm sure that has nothing to do with it. What I DID do that caused this problem was follow the openoffice dark theme fix on this page:[URL]
BACKGROUND: I installed a dark theme that made the openoffice word page black, so I had to find a fix for it on the page above. I'm not using the theme anymore, but it was "Slickness black" on gnomelooks.
In case someone didn't see a problem with the orginal login screen, the section where you click the username and enter your password should look like this:
Also incase anyone was going to ask, my login DID look like the second picture at one point (before the openoffice fix) I just removed openoffice completely and reinstalled it so that isn't the solution.
I have gone from Suse 10.3 to 11.3, completely refreshed. I used to have boot screens really nice ones come up at random after Grub loaded.
Now with the 11.3 that is gone. I looked at GDM and see it is different from my previous version and does not seem to have the option to have the login window. Is there any way to get back the old version of GDM?
I upgraded to Natty at the beginning of May and Unity has been working fine until about 4 days ago. Around then, then I cold boot and log in, Ubuntu starts in "Ubuntu Classic" desktop. If I log out then back in, Unity starts as expected.In both cases of my logging in, Ubuntu Classic is not selected - Ubuntu is, which should start the UI under Unity.
First of all not sure if this is the correct forum but anyway.Ok well i installed this theme because i liked the look of windows 7 (http://gnome-look.org/content/show.p...content=113264).So i ran the GUIUninstall.sh and it seemed to work but the login screen still has the theme i was wondering how i could change it back to the defualt one.
1st Problem:The problem that I am having is for Ubuntu 10.10. When logging in for some reason it will:1. Login and play the Ubuntu login sound.2. Will start loading the desktop and panels.Right after #2 it goes black and kicks back to the login screen. I am not sure what to do since it constantly does this. It renders the computer useless if I cannot get passed the login page. Yes the username and password are correct.2nd Problem:Before this 1st problem occurred this has also been a problem that has not went away.When I used to be able to login to the desktop I have just the panel on the top of the screen with the traditional Ubuntu "start menu", "system", etc. For some reason the right side which is the other half of the panel will not load. The only solution which fixes it while I am on the current session is to right click the panel and click Minimize/Expand button which toggles to center the panel on the top of the screen. Now when I click Expand its like the problem never happend, but this only fixes it for that session.
This problem has been discussed a couple of times here and there and there are numerous solutions as well as unsolved stories. The topic says it all I think. I use ca(fr) layout, and in the gnome keyboard configuration (system, preferences, keyboard) I only leave Canada. When I log out and go back in, the layout changes to USA and in the configuration tool, theres canada AND usa. I have to delete USA every time. The file /etc/sysconfig/keyboard is already set to ca(fr) and doesn't change
I tried to delete: rm -f /var/cache/gdm/your-username/.dmrc rm -f ~/.dmrc
but I either did miss something or it didn't work. The only thing I observed is that if I set the keyboard layout to Ca(fr) at the login screen (which is always set back to USA), the layout stays to ca(fr) in my session. This problem did not occur on Fedora 11 and it began on 12 on my laptop as well as on my girlfriend's.
I've read somewhere and I forgot where, that it is a known bug in Gnome and that it is fixed in a later version. I applied all available updates and system/about this computer says I have Gnome 2.28.0 and if I recall, this bug is supposedly fixed in 2.28.4 but I may be wrong on the version number. This is very annoying as we try to turn our computers off when we don't use them but this reset every login kind of forces us to our previous bad habits.
Whenever I logoff my workstation, I log back on and my desktop doesn't come back. Only the mouse pointer and the wallpaper show up. The panel and the shortcuts don't show. I have to power off using the power button, then power back on to fix.
My problem is basically that when I boot for the first time after a fresh installation and setup, I am always stuck at the login screen or thrown back to it. No matter what account I log onto, whether it's 'root' or any other user account I have setup, it would attempt logging in, black out the screen, turn my monitor off then on again and I'm back at the login screen. This is all using the graphical interface of course. I'm having this same problem with all the linux distributions that I've tried so far:
Gnome Sabayon Mandriva 2010-I've even tried changing all the different boot environments, and same problem Open Solaris and Ubuntu won't even install. It just sits at the loading screen. Why would this happen? I've tried all these OS's on my regular PC, which is a dual core, 4 gb of ram, and they've worked perfectly. So why wouldn't it run properly on that other PC?
I use firefox3.6.x, and i play online video (sockwave flash) often, but while opening the page (often has swf), the whole X restart, and back to login window of gdm. The problem not accured everytime i open the page, but very often. I met this problem both in ubuntu 9.10 and 10.04, and also lubuntu 10.04. So, i fall back to use firefox 3.5.9, and evrything seems fine.
I tried applying an emerald theme yesterday, and when I did, it somehow affected the login screen, now it looks old and crappy like win98. I tried disabling emerald and even uninstalling it, but the login screen remains crappy, how do I get it back to the way it was?
