Ubuntu :: Login Via Gdm - Error Initiating Conversation With Authentication System - General Failure
Jun 13, 2010
I was having a problem with the keyring asking me for a password after I changed my user password. I googled it and found that since the password changed, I will get asked for the keyring password until I delete ~/.gnome2/keyrings/login.keyring. What happened was that I wasn't paying attention that you had to generate a new keyring password before rebooting.
Now, whenever I try to login via gdm, I get this message: error initiating conversation with authentication system - general failure
How do I get it working again? I can still login from the terminal.

Tried to make the /etc/pam.d/gdm mod to auto-auth keyring. Now when I boot up it says "error initiating conversation with authentication system - general failure" preventing me from logging in.
So I read that I can enter recovery mode by pressing Esc on boot up to boot to a root shell. However no amount of button mashing Esc on boot up seems to have any effect, always bringing me to the graphical login. I could boot to a liveUSB but this has all started when I got to work this morning, and don't have a USB key handy, and I'd like to get this sorted so I can do some work today!
And why does the /etc/pam.d/gdm tweak seem to be causing so many issues (googling reveals the technique has a lot of other users finding the same problem as me, however they seem to be able to get to recovery mode)?
EDIT: If I hold down or mash Esc fast enough, the computer will beep at me once or twice, but nothing changes on screen
EDIT 2: Ok found out that holding SHIFT is the new way of doing things, reverted pam.d/gdm to the backup and things are back to normal!

i have been running Ubuntu for about 3 days now, finally getting all my files moved back to the drive and what have you.I came from running windows, and an Android phone with full su access, and done up all custom-like..I am loving the speed, etc. great experience so far. BUT: the headphone port on my laptop is broken, and so I run [ran] and external soundcard, a Creative X-fi 5.1 USB SC. I have found linux drivers for this unit, and am trying to install. I have googled the crap out of how to do this, yet am getting stuck.
Here is where I'm getting stuck. I have extracted the package, entered into the sub folder, and am trying to run the Make install:
...laptop:/tmp/xfi-0.0.0.0$ cd ./xfi
...laptop:/tmp/xfi-0.0.0.0/xfi$ su -c "make install"
Password:
su: Authentication failure
...laptop:/tmp/xfi-0.0.0.0/xfi$
what in heck do i type at password... have I NOT done something, am I doing something wrong.... it does not accept my normal password, so I am lost.

I just got Fedora 12, and I used su root to change the bin ownership to my primary developer account. For some reason, though, all subsequent attempts to log in as root have had authentication failure, be it through su or through the startup login screen. This does NOT occur for adminstrator tools such as Groups and Users.

Debian 5.0. Lately after login following warning popup;Your system had a kernel failure
There is diagnostic information availiable for this failure. Do you want to submit this infomation to the www.kerneloops.org
-> Yes
$ uname -aLinux vm0.debian50 2.6.26-2-686 #1 SMP Wed May 12 21:56:10 UTC 2010 i686 GNU/Linux
Reboot to old kernel 2.6.26-1 the said warning doesn't popup. Reboot again to kernel 2.6.26-2 and after login no kernel failure warning popup. I did it twice. IIRC I encountered this problem before.

we are using linux email server axigen past few years. we keep port open ssh and pop,smtp webmail etc. ssh use for remote trouble shooting. so through firewall it is globally accessable. we notice many attacks coming to our machine, also some people try to enter in our system but failure. as example see below a log come in messages file
Mar 17 09:19:50 sa1 sshd(pam_unix)[21231]: authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=210.51.13.120 user=root how we can secure more. as per my understanding only good long strong password can stop to prevent from attacks.

I have (had) Debian Testing running on a 250GB IDE hard drive, partitioned normally.
I also have 4x 1TB drives in a raid 5 using mdadm, and 2x 500GB drives in a raid 1 also with mdadm.
I put the two arrays in lvm using:
I then used "lvcreate" to make storage/backup 300GB, and the rest went to storage/media (approx. 2TB usable). I put an xfs filesystem on both and mounted them.
All was working fine until the system drive shorted out and died on me this morning. As far as I can tell, all my other drives and everything else is fine. I do a daily rsnapshot of the filesystem, which of course is residing on storage/backup (stupid, I know). So I have full backups of everything, but I'll have to put a new hard drive in and reinstall Debian before I can restore everything.
I've reinstalled before and simply reassembled mdadm arrays and remounted them before with no problems, but this is the first time I've used lvm, so I'm not sure what I have to do to restore everything. Is it as simple as reinstalling the system then doing a:

I am running Ubuntu 11.04 which I like very much (except for Unity - so I am using Ubuntu Classic).
Whenever I try to use "su - " I get Password Authentication Failure. I have checked Caps Lock (obviously) and have also tried resetting the password using "passwd" - but with no success.
If I use "sudo ...." with a command the password is accepted.
I have the same software installed on two computers but the problem only occurs on one - the other is OK!

su doesn't work in terminal. i found one (click), and tried it, but it didn't fix it. Everything else works. Sudo, Software manager, synaptic package manager... I know i'm putting the right password in. Heres a picture, ignore everything except the last 4 lines.
Everything before it was me trying a proposed fix in the thread mentioned above.
Quote:
sudo dpkg --configure -a
sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade
I've tried changing my password as well. I got the same error. Also, "sudo su" works fine. I'm not sure if theres a difference as i'm new to ubuntu....linux in general. Can you explain the difference between sudo and su, and sudo su? Also, can you explain what any commands you need me to do are? that way, i'm not just leaching.i'm trying to do is install Java!

Im using FEDORA 12 (constantine )....Everything was working fine.....until yesterday when i tried login to my GUI(gdm) it says authentication failure. so i tried logging in from CLI and it didnt worked either...(it didnt say "password incorrect",rather it it simply reset the screen to "login name:",thats weird...right?)
Then i tried to login as root from from CLI (by default Fedora does not support root login to GUI?) and i was able to login.....
Then it said "System powering down in one minute"............. i didnt understand why that happened.....! but it didnt power down in one minute...
I tried changing my user passwd...still no change.....

I managed to get Ubuntu installed, however, it just won't let me log in. I perform the net-install, and tell it my user name and password. However, once the install has completed, and the system rebooted, I cannot log in to Ubuntu (on X-screen or TTY). I've tried it twice - once with Karmic Koala Ubuntu installed with GNOME - the other with just CLI and they both fail.

I upgraded from 8.04LTS to 10.04LTS desktop. I can do sudo as root at the terminal, but I can't pass authentication trying to add a user (System->Administration->Users and Groups).
Here is what I got: An error occurred while checking for authorizations: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. You may report this as a bug.

Here is what happens. I type in "su", without the quotes, to switch to root. I enter my password.
Code: jon-Tuxbox:~$ su
Password:
su: Authentication failure
jon-Tuxbox:~$ It fails, and I get kicked back to the command line. I recently fixed the permissions on the shadows file and the su file in the bin directory, and that is what caused this. Before it would give another error. I tried resetting the password for root, but it didn't fix it.

I have a computer with three video cards and six monitors. Works great on Windows. Trying to get it to run Ubuntu 10.4 as well. It loads fine when I have it configured to run on one adapter; detects both screens, runs ok. But I want to turn the other 4 monitors on and run the whole thing as one extended desktop (one session, etc). So I downloaded and installed the newest ATI driver for Linux, which seems to work, kinda. I ran this to set up the screens:
aticonfig --adapter=all --initial -f Now when I boot, Ubuntu seems to turn on all the screens (3 viewports, each with two cloned displays from what I can tell). When I enter my login info OR move the mouse off the main screen, the screens freeze and the kbd/ms become unresponsive.
