Debian Installation :: Can't Login / What To Do?
Feb 8, 2011
Just installed Debian 6.0 with kfreebsd kernel. I did not activate root-account, but a user-account. installed grafical user interface.
When I reboot after install I came to a login window with my user and asking for the password that I type, but after that the login-window get grayish and nothing happens.
I also intalled sshd and are able to login to the terminal from another computer and are able to do things from there.
Please what can I do?

I made a huge mistake. I was installing dtc-toaster in a Lenny box, and i accidentally closed the aptitude window. Then I opened another konsole (I have kde 3.5 installed), and I couldn't switch to root via "su" command. I can't remember the error message that i got, but it was something like "module not recognized".
Next i reboot the PC, and when I tried to login in tty1, system saids that root "is not a valid username". I had no better luck with other users.
As I'm not an experienced user, I really don't know where to begin. The good news are that starting in recovery mode seems to work.
I have no extra data by now, except that I ran fsck (from a System Rescue CD) on the lenny root partition, and it found no errors.

Debian 8/Cinnamon fresh install. /home is being shared with two other OS's, Mint and openSUSE. At the login screen I enter my user name and password and the screen blacks for 1-2 seconds and comes back asking for user name and password. I can login as root. As root I can launch the Group & Users GUI and attempt to set the user's password, and pressing the 'change' button does nothing obvious.
I can set the user's password in a terminal, which reports success. I tried to switch users and login with the changed password and I get the same failure. If I try to login with the original password I get an incorrect password error, suggesting that the password is being processed properly and the problem is elsewhere.
On previous installs with Mate and the default desktop (Gnome) I didn't have this problem. So, the questions are: Is it Cinnamon? Is it an unlucky chance bad install? Config files are typically in /home, which is being shared with Mate and KDE, is this the problem?

I have recently installed Debian Lenny with KDE3. I foolishly checked Auto Login after installation and now I can't get rid of it. The KDE Login Manager window seems to offer the option of turning off auto login, but it does not work. I have tried useradd and userdel but this only makes things worse.

Suddenly Debian started rejecting my user pw and I have to login as root. Perhaps this is a coincidence, but this started when I re-booted after adding Russian keyboard layout in etc/default/keyboard. The Russian keyboard added successfully.
Being logged in as root, renewed the pw of my user account (actually assigned the same as wes previously), got confirmation the the pw has been changed. Reloaded. Yet it keeps complaining that the pw is wrong.

I've installed a fresh Debian amd64 DVD version on my small HP Compaq 6537s / AMD Athlon X2 / 64. Everything went fine, I rebooted, the graphical login screen appeared, so I thought I will be able at last to run Debian on a computer ...
But then after login, the login Window disappeared, the "Debian" logo too, and... that's all folks! A nice blank screen. But the mouse is still perfectly drawn, so it's kind of weird.
Here's what tells me "uname -a" :
Linux olivierdebian 2.6.26-2-amd64 #1 SMP Sun Nov 21 09:17:22 UTC 2010 x86_64 GNU/Linux
If I go to CTRL-ALT-F1, i login as root and I do a "/etc/init.d/gdm restart", I have the login screen back and this is once again the same scenario: login => ok => blank screen with mouse properly drawn and the Debian background color still there.

I initially installed Debian 8 onto my iMac G5 (with KDE), and it would boot to a black screen. I then tried again, and reformatted+reinstalled with only "Standard system utilities", "Print server", and "SSH server".The boot hangs before I get to a log-in prompt. Please see the attached log files I pulled off by booting from the rescue CD option. (I got an error when attaching the log files, so I used tinyupload to upload the files.URL....
Here's some of "syslog"

I just downloaded Debian's live CD .iso file. I put it on a USB stick and booted from it. It loads everything then presents me a login screen. I have no idea what the login and password is I've looked all over google and people said it was user: live pass: live or something like that. I've tried a lot of different combinations with no luck. So does anyone know the real username and password for this?

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.

Having installed Debian 7 on an old machine from a Liinux Format Magazine DVD I was unable to log in as a specific user. I can login as root and use useradd etc but when I logout of root I still cannot login as a user and nor will the machine accept my root password. I have to shutdown and reboot to get back into root. I'm using O'Reilly's Linux Pocket Guide from 2004 for the commands. Could it be that things have changed?

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 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 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 downloaded the .ISO for Fedora Core 14 Live, with the intention of installing it to my HDD.
I burn the .ISO with no reported problems.
I boot to the installation CD and can get to the point where it asks me to Login (a timer is also going down for Automated Login).
Once I click "Login", nothing else ever happens.
I can hear the disc spinning in the drive and it's trying to load something, but it never does.
I thought that maybe my older (2003) laptop might just be slow, so I allowed it to do whatever it seemed to be doing overnight while I slept.
Well, I woke up this morning and it was still doing the same exact thing with no results.

Oh, and I intend to dual-boot. I have already made a partition using Norton Partition Magic. It's NTFS filesystem for now, but I figured the Fedora Installation would give me an option to use that partition anyway - NTFS or not (meaning, it would wipe the NTFS file system and use whatever it is that Fedora Core uses). Am I mistaken in assuming this?

My dns/firewall Debian7 server (no GUI) was installed with a LDAP client.This client is now useless as no user needs to connect to that machine, so I changed PAM configuration to remove LDAP users from local users.The problem is that I can't login anymore as root or as administration user.The password is unchanged and when I try to login with it it gaves no error, but go back instantly to "login :"On the other hand, when I try a wrong password, it react as it should with an authentication failure.That's why I don't think it's a password issue.
The server still works as far as I can say no service was impacted, I just can't login anymore (and that will be an issue when it comes to some upgrade or administration...).

I just installed debian 5.06 i386 130MB that I downloaded yesterday(Monday).My problem is that when an incoming ssh connection to this debian box is established, but nothing is being logged to /var/log/auth.log on this box. I've tail -f the auth.log which verified nothing is getting logged for ssh. The auth.log is showing activity, mostly root logins and logoffs, but no ssh activity.I understand that /etc/rsyslog.conf may control what gets logged. I had pastebinned this file on #debian but people noted that it looked fine.I have not made any changes to the system, like editing config files or anything. The system is essentially just out of the box.What else can I do to figure this out? Otherwise, I am pleased with how Debian installed on 2002 vintage machine, and is running in console mod
