Ubuntu :: Unable To Login / What Is Going Wrong?
Jun 25, 2010
I am running Ubuntu 10.04 from an external hard drive. I am able to get to the GUI login and enter the correct user/password combination. However, one I push enter it cuts away to a blank screen then returns to the login screen as if nothing happened. This doesn't happen if I log in without GUI (using alt+ctrl+f1 (or any other function key but 7).
Can someone tell me what is going wrong? I am still able to access my files from the hard drive by booting from a live CD if that matters at all.

I'm running 10.04 and whenever i go to the login screen, the username and password window is on the wrong monitor. I'm also using an ATI Radeon HD 4850 if it makes any difference.

I've been working my butt off all day now trying to get the nvidia drivers installed and then (the hard part) get dual screen to work properly with them installed. Finally I've gotten to the point where both of my screens are working perfect but now the login screen is on the second monitor instead of the first monitor for some reason I do not know.
Here's my xorg.conf:
Code:
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 1.0 (buildd@crested) Sun Feb 1 20:25:37 UTC 2009
Section "ServerLayout"
Identifier "Default Layout"
[Code]....

one of them is a TV with an HDMI input. The login screen shows up on the tv, so if someone is watching a movie, I have to pause it to switch inputs and login. Other than that, everything is fine. How do I get the login screen to show up on the main monitor?

I have 2 monitor on and Nvidia FX5200 set up as twinview
Monitor 1 is an old Sony CRT @ 1280x1024
Monitor 2 is a Visio HDTV @1920x1080
I have setup Monitor 1 to be the primary using nvidia-settings but the GDM login keeps sowing up in the second monitor ; before the HDTV I had a CRT TV @ 1024x768 and all was good. My theory is that GDM determines the center of the Screen (both monitors together) and then centers on that monitor. If this is true then how may I override this behavior and force the GDM login to show on my primary monitor?

Seems like a nasty bug in F13.after typing in wrong password, a 2nd correct attempt on gdm (or kdm) leads to a dark screen with a dash cursor blinking on the upper left - have to turn machine off. Then on next login, memory seems to race until properly shut down.

I use a Dvorak keyboard. I recently installed F13, and the layout is correct in the console an after logging in, but at the login screen, it goes to QWERTY. I've tried all of the settings in the GUI configurators; all of those are set right. There is no xorg.conf; so, I can't change it that way.

I have a laptop connected via HDMI port to different external displays throughout the day. I have configured the displays (Settings > Displays) to turn off the laptop display and set the external display as primary. However, this setting only takes effect after login. Thus, I am unable to see the login screen greeter on my external display because I close the laptop lid, so I am logging in blindly to a gray login screen background.
he issue I am facing is that when I start the laptop with an external display connected, the greeter only appears on the laptop display. The gray login screen background image spans both laptop and external displays and my mouse pointer appears on both displays, so I know both displays are detected and configured as dual displays. But, I am guessing, the laptop display is set as primary while the external as secondary.
I would like to know if there is a way to dynamically switch the greeter between the two displays, regardless of which one is set as primary and secondary. Or, is there a way to configure the system such that if there is an external display connected via HDMI, then it is set as primary, and if no external display is connected, then the laptop display is set as primary?
I have searched all over the net and this forum to no avail. I read a post which required copying the user's ~/.config/monitors.xml file over to /var/lib/gdm/.config/ but this caused my laptop monitor to be turned off at login even when there was no external display connected.
Hardware: Acer Aspire 8730G, Core 2 Duo T9900, 8GB RAM, Nvidia Geforce 9600M GT.
Software: Debian 8.4 Jessie, Gnome 3.14.1, Gallium 0.4 on NV96 (I am assuming this is the Nouveau driver)
Contents of the /etc/X11/xorg.conf file which I generated with the command "Xorg -configure" as root in console mode:
Code: Select allSection "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection
[Code] ...
I suppose I will continue to login without seeing the greeter on my external display.

I just happened to lock myself out of ssh access on my xen virtual server since I changed the ssh port but forgot to open it in the firewall. No problem, I just access it through VNC in VM manager, I thought, however I have some special chars in my root password and the keymap through VNC seems to have changed somehow. So I cant login as root, nor do su or sudo. I can login as user. I need the sign " but can't figure out how.

I recently installed Linux Mint and went through the whole business, but when I go to my DNS's it just goes to my FIOS login.
dns:
foxwebhosting.dyndns.org
foxwebhosting2.dyndns.org
I tried everything in mind, but I think the big issue has to do with the reason why it's picking up the FIOS login and not even the index of my server.

I have just fresh installed Fedora 15 over my (very) old copy of Fedora 11. I wanted to play around with Linux.
Anyway, when I log in, I get the "Oh no! Something has gone wrong" (like I stated).

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.

I work on a product that have to start automatically an application. Running Opensuse 11.2 So in the inittab I have : 1:2345:once:/root/Velox/VeloxBoot.sh 2:2345:respawn:/sbin/mingetty tty2
In the VeloxBoot.sh, if I don't press any key, my application starts after a timeout. If the user presses a key I want to have a login prompt. Unfortunately, if I start /bin/login, I have a prompt with login, but once I enter my login, it does not ask for a password and it says wrong password

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.

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?

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.

I've tried to test 10.04. One, by upgrading a working KK installation. The other, was a fresh install. Both were as VMWare virtual machines.Both installs had the same problem. The install/upgrade process goes smoothly. When the GUI logon screen appears & I click on the user name, I'm unable to type in the password box. Nothing appears. If I then click "continue", the result is "authentication failure".

I have a problem using Ubuntu 10.04. When I try to login, the screen turns black or white for a second and then returns to the login screen, without giving any error. Logging in in tty1 works fine though.
I have already tried some commands that might be of use. "sudo gdm" gives the following error:
Code:
/etc/profile: 29: [[: not found
** (gdm-binary:2265): WARNING **: Failed to acquire org.gnome.DisplayManager
** (gdm-binary:2265): WARNING **: Could not acquire name; bailing out
"gdmsetup" gives this:
Code:
(gdmsetup:2272): Gtk-WARNING **: cannot open display:

I had a mysql package that wouldn't install correctly and was informed that the fix was to install dtc. Well I installed dtc and everything appeared to go fine. I now can't log in as any user and the only way to get back onto the system is in repair mode. Even uninstalling dtc with purge doesn't help.What do I have to do to fix it so my logins work correctly again? I have looked on Google and other sites for a fix and nothing seems to be working.

Just installed Ubuntu 10.10 as a dual boot on a Windows Vista laptop. Usually when I've installed Ubuntu on other machines it's asked me to set a user name and password. In this instance, it's automatically taken the same user name as is used to login on Windows.When I try and log in on Ubuntu, it comes up with th user name from Windows, busks for a password. On Windows, there's no password set, so I don't know what to put.I've tried things like 'password' and 'Password' and the likes. I also tried going onWindows and adding a password there to see if Ubuntu would find it, but no such luck.

After my last upgrade from 10.? to 10? my users' (kids) were unable to login. I tried to fix it and could not find anything wrong. Now I have upgraded to 11.? and the problem persists. The users could still login by selecting an older version at the prompt during boot up.
I deleted there account and reinstall the user and still they could not login. I added a completely new test user and could not log that one in either. The system excepts the password, waits a several seconds, then the mouse curser changes to the spinning circle. The hard drive lights flash for many seconds then eventually the hard drive stops flashing. I have let it sit a long time and it never continues. Tonight I came home tried to login and it is doing the same thing to me tonight. I ran fix packages, fix grub and everything else I could think of and could not log in.
Finally I logged in to the oldest version on there and it let me in.? The screens are all the same but the desk top is entirely different? I have never seen one like this. I think its like the new version of fire fox, with every thing moved around. Icons down the side. Menu's hidden at the top? I can probably get used to that but I need to able to login, and my user's to login?
