Ubuntu Installation :: Gui Login Fails In 10.04 But TTY Login Works?
Jul 11, 2010
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.

After login-in with gdm, the desktop fails to launch.
I can only move the mouse, clicking does nothing, no hotkeys; no desktop.
All I can do is change to a TTY.
I have tried restarting the gdm service; this just lets me log in again to the same stalled desktop.
The panel at the bottom of the gdm doesn't list any sessions, all it has is universal access and the time.

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?

Fresh install of Fedora 11 x86_64, ext4 file system, Intel Quad, 1 Tb disk
Went through install, defined mike as user with password
reboot, get graphic login (init 5); cannot login as mike OR AS ROOT!! (unable to authenticate)
use live cd, reset inittab to start at level 3
reboot, get user prompt on terminal at level 3
enter mike and password, system wait a minute or more, returns to login prompt (obviously timing out --- dbus problem???)
enter root and password, get in, issue startx
open terminal window, and issue "su mike" command, ten minutes later, finally get terminal with mike as user.
Use ctrl-alt-F2 to get a terminal, type mike, and password, no joy; login as root and type "su mike". Go back to Gnome screen at F7, so I can continue to type this , and check back at F2 periodically to see if "su mike" ever takes. After three minutes, still no joy. After five minutes, it worked. whoami shows "mike"

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
[Code]...

I have a working LDAP-server (I belive!!) I want my laptops to authenticate against the server, when they logon. That works fine as long as the network is present. But I also want the users to be able to log on, when the network is down. When I go to a terminal (without network) I can su to another LDAP-user.I can login via graphical login-screen with the network attached, but not when it is disconnected.
In a terminal id john gives me information about the user john.
My conf. files looks like this:
/etc/ldap.conf
host 172.16.0.138:389
ldap_version 3
bind_policy soft

Has anyone ran into a problem running Startup Applications from automatic login? I have checked to see that it is not loading in fail-safe mode, and if i disable the automatic login it works fine. The file it is loading is located in my home directory and being executed as

i have setup auto ssh login for my server. And it works, but only when i have a active connection. if i use "ssh server.com" it asks for my password. If i then open a new terminal and issue "ssh server.com" it logs right in. I really don*t understand whats wrong.
I have tried setting up 2 virtual machines on my local computer and with the same setup it works fine.
SOLVED: my home folder was encrypted, so when no users were logged in the home folder was unmounted

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 an Ubuntu 9.10 server and i need to use an ftp server. I installed vsftp but i can't make it to work. What doesn't work is that can't login to the ftp server with my user(s).I created a user ("AddressBookUser") that should access to some files located on "/var/www/fpt/rubriche/". I set this folder as his home.Here is the row for this user in /etc/passwd:
Quote:
AddressBookUser:x:1001:1002::/var/www/ftp/rubriche:/bin/false
This user is member of the group "rubriche_ro" (and no other groups).This is my /etc/vsftp.conf:
Quote:
listen=YES
#listen_ipv6=YES
#
anonymous_enable=YES
[code]...
vsftpd.chroot_list exists, but as you see above the chroot_list_file directive is disabled.When i try to connect to the FTP server the connections is established but after i insert "AddressBookUser" as user name and confirm i get a "530 permission denied" message. This occurs both from the network (LAN) computers and locally:
Quote:
webs@webs:/etc$ ftp localhost
Connected to localhost.
220 Welcome to WEBS FTP service!
[code]...
I can't figure out what is the problem but my thought was that it's a problem related to the user configuration rather than vsftp configuration, but it's only my supposition. If i try to login with the "main" user of my Ubuntu server, "webs" i can login correctly.

I'm running a fresh install of Ubuntu 10.10. Sometimes, on attempting to login, the screen resets and I'm brought back to the login screen (though I know I have the right login information). The only way around is to restart. Also, sometimes when I do finally get in, my taskbars won't even appear.The machine is an HP workstation x1100 with Pentium 4 and fairly old graphics card (using AGP). Is the computer just not compatible with linux?

Fedora 9 used to support a timed login via the gdm program. This feature no longer works with the gdm that comes with Fedora 13 (gdm-2.30.2-1.fc13.i686 ). I made modifications to /etc/gdm/gdm.schema as follows:

Is there something else I have to change now?

I've run into a strange problem with GDM that I haven't managed to find a solution for yet, either by trying myself or googling, and I have run out of good ideas. I'll just infodump here about the problem and what I've tried etc;
I installed Ubuntu on a new PC a few weeks ago, setting it up with autologin for my mom and a separate user for myself, using the on/off-icon menu in the top-right corner to switch to my own user and back as needed, and logging the user out when done. This worked quite well.
However, a few days ago, this stopped working; logging out or trying to switch now leaves me with a blank black screen, without even a mouse pointer (but not off, the backlight is on).
EDIT: To clarify, this is an issue that only affects the GDM login screen, but that affects it whenever it is used, wether it is on boot (when not set to autologin), after logging out, or when trying to switch user.
At this point, I can usually use Ctrl-Alt-F1 to get a textmode login, and Ctrl-Alt-F7 to get back to the auto-logged in session (assuming I tried to switch, not logout).
I can't think of anything specific I did or installed around then that should be related in any way...
I tried disabling autologin and restarting gdm, which left me with the same black screen (which is still there after rebooting), instead of the expected login window. I managed to re-enable autologin by manually editing the /etc/gdm/custom.conf file, so that it would at least work for mom.
I've also tried to change which user is auto-logged in, thinking it might be a problem with my user account, but both users get an automatic session just fine when I restart gdm.
I thought it might be a problem with the video driver, but that's not the case - if I run zenity --info as root with DISPLAY set correctly, the dialog box appears on the screen just fine. It has no borders or titlebar (there's no windowmanager), and is apparently without keyboard focus, so since there's no visible mouse pointer I can't click the OK button... But since it appears, X is apparently up and running just fine, just has nothing to display other than a black background.
I tried purging and reinstalling gdm and gnome-session(-bin|-common), but that didn't help any.
Running ck-list-sessions after trying to switch indicates that there's a new session there, with session-type = 'LoginWindow', so it appears to think everything's fine.
Enabling debug output in the /etc/gdm/custom.conf file did get me some more debug output in the gdm logs, but it didn't really tell me anything, there weren't any obvious problems that I could see.
After some looking around, I've guessed that it's supposed to be running gdm-simple-greeter, which I assume would display a login box; trying to run it manually doesn't work though (it's missing some environment variables, and trying to add them based on the abovementioned debug output doesn't really help).

I'm running 11.04 desktop 64 bit and have smartmontools and mdadm set to send automated test emails at bootup (I have a RAID5 setup).I'm using msmtp with a gmail account. When I'm logged in, I can manually send test emails with both smartmontools and mdadm; neither will send me an email at bootup even though they are set to do so. The msmtp log at bootup has a smtp.gmail.com exitcode=EX_NOHOST.why it can't find the smtp server at bootup but has no problem once I'm logged in and test it manually? Is there some dependency that isn't loading in time at bootup???

I did a fresh install of the netbook version of 10.10 on a Gateway CX2618. I ran all updates and then rebooted. I installed LWO 5.4 from the repository and joined the domain. I put in a kerberos realm (same as my domain) but I don't know for sure if I have a kerberos realm. I successfully joined the domain with the GUI. I rebooted, per instructions.
I tried to login with domain username and password (DOMAINusername). It takes a couple seconds to think and then kicks me right back to the GDM login screen. I have tried several times with the same login and have tried other domain users. It doesn't say "authentication failure" but I should have tried to use the wrong password to see if it would do the same.
I'm stumped. Is there a ppa I need to add? Is Likewise-Open supposed to work with the maverick netbook edition. I saw the previous notice on the Likewise site about OpenLDAP but I thought that was resolved in the updates and no longer in effect. Should I install LWO 6.0? If so, from where? From a ppa somewhere? From the Likewise site?
I can still login with a local admin account.
My ultimate goal is to automatically mount network windows shares for various students, based on their login credentials and using CIFS. I almost had this figured out before this fresh install.

After changing my user's UID number with the "usermod -u" command or otherwise changing the login settings my computer no longer logs in automatically. I can login manually by selecting the "Other" option and manually typing in my user-name and password. However my user-name is gone from the list of users at the login screen or in the Login Screen Settings program.
Other than that my computer seems to function fine. My users details are still listed in "User settings".

I've been running xubuntu for a few weeks now, but just today I began having a few problems. When I boot my computer, it simply freezes at the xubuntu logo just before the login screen.
The last thing I remember doing before this is typing export DISPLAY=:0.0 in the tty1 terminal.

I'm running an LMDE install, but with the Sid repositories.Everything has been fine until yesterday's updates, after which I can't boot normally. The boot hangs at the login screen, and nothing works - not the mouse, the keyboard, the touchpad, nothing, and it requires holding the power switch to get out. I can boot to a root recovery console, but networking doesn't work at all there. I can run startx there and get an X desktop as root, and networking still doesn't work. No wireless, no ethernet, no nothing. From the recovery console I can run shutdown, and when prompted for a password, can enter Ctrl-D, which immediately drops me back to X, to the normal login screen, which now works normally, and I get a normal X session in which everything works. This is the same for all installed kernels, including 3 versions of the Liquorix kernel and the standard Squeeze kernel. It would appear to be something in my settings in /home, but I can't find anything that looks suspicious. I ran smxi again after booting through the root console, without any improvement.

I run a CentOS 5.1 using VMServer on XP. From home I can successfully 'cvs login' to my CVS server. But starting 'cvs update', the connection times out.
Netstat shows the connection as established:
# netstat -an | grep 2401
tcp 0 0 192.168.1.35:58651 85.25.xx.xx:2401 ESTABLISHED
CVS server is domain managed with dnsalias service (dyndns.org)
Using the same computer at work (other ISP) I have no problems - cvs update works just fine.
Can I assume that it is not a port/firewall issue, since "cvs login" is successful? Any clues where to start diggin'?

I built a 11.04 server system in vmware workstation a few days ago, set it up for something and now I have a strange problem. It boots without problem. I can login via ssh, the services run and everything is OK from the outside. But on the console there's just a fast blinking cursor on the screen, no login or anything to that affect. Just blank and a blinking cursor.

I joined my Ubuntu 1004 LST to Windows 2003 AD.
it always frozen my ssh login window when the DC crashes. when the DC crashes, the putty won't give me the password prompt and will go inactive directly after a while no matter what username(local or domain users) I give
is it possible to avoid to check domain users before it gives me the password prompt? or, we can make it to check if the user is a local user first?

Basically, the problem is, we have a bunch of computers in a computer lab, that we want to students to access, but not modify in ANY way. That includes backgrounds or whatnot. And after restart, any changes they may have made, change back. Also, they can't have read access to the administrator account on the computer.
This needs to give a permission denied, or something:
Code:
cd /home/(admin account username)
ls
The Guest Session is exactly what we are looking for, but try as I might, I can't get it to work. Because, we don't want to have to login as administrators, then activate guest session, just for our students to use the computers. The idea being, we can leave the computers in there, and not worry about the students breaking anything.
One thread I tried was: [URL]. However, using his method, will log the student into the account, and after about 5 seconds, log them back out.
The other method listed lower in the thread,
Code:
/usr/bin/guest-session
Seems to work, but upon logging out, fails to launch the gdm
Only way to restore is restarting the computer.

I have been using my system for couple of weeks, and normally update software when the icon is displayed on top bar (gnome). Last couple of days there were updates for X, and I am not sure whether that is the cause of my problem. Once bootup, I get the login screen. When enter the password the login screen keep coming back. there is no error about any password issue, or anything. It keeps prompt me to enter the password.
I could login back the following way.
1. ctrl + alt + F1 , and login with the same username/pwd as for X
2.change to root
3.pkill gdm3
4.exit from root to user privilege
5. startx
The system starts X correctly and no login screen is displayed. I could use the system as usual.
The only thing I did custom to my system was upgrading to the latest kernel (2.6.38) using the source. This was to get support for my hardware, but that was about a month ago. I do not see anything in /var/log (X, demesg etc).

So I've configured ldap on Centos5 64 bit and I can run "ldap search" and "gentent passwd" on the client/server and it shows my users info.
But I can't login via the cli or GUI.
I can login by doing;
su - username
at the client or server but I can't login by issuing;
login username
or at the GUI login screen.

I rsync-ed root fs as a whole to another hard drive. In grub.conf I changed kernel option
root=/dev/sda1 ---> root=/dev/sdb
After kernel mounted root filesystem on the new hdd and all services started I successfully got prompt to enter login and password. However after login I immediatelly logout automatically. Here is /var/log/secure output:
Quote:
May 20 23:53:18 localhost login: pam_unix(login:session): session opened for user alex by alex(uid=0)
May 20 23:53:18 localhost login: LOGIN ON tty2 BY alex
May 20 23:53:18 localhost login: pam_unix(login:session): session closed for user alex
What is printed before this:
Quote:
May 20 23:50:47 localhost pam: gdm-password[1469]: gkr-pam: couldn't run gnome-keyring-daemon: Access denied
May 20 23:50:47 localhost pam: gdm-password[1455]: gkr-pam: gnome-keyring-daemon didn't start properly properly
Neither of these quotes appears if the initial file system (not rsync-ed) is used as root fs. I guess that pam might use information of hard drive, for example, its serial number, and login is tied to a disk. Please, give me a suggestion how to get rid of automatic logout.

I m try to explain the structure I tried to use here:Symptoms: Describes what is happening right now What happened: Describes the history leading to the problem My tries so far: Describes, what I did (so far in vain) to clean up the problem Questions: I already searched the forum (see "My tries so far") but missed to write down the URLs for the threads. (So they aren't mentioned under "My tries so far")
Symptoms: The system boots up ok, I get to the KDE login, but for both my user account and the root account, the login fails. After entering username and password a progressbar comes up. This gets to 3/4 (if I counted the steps correctly) then stops. If I wait for several minutes, the screen will finally just turn black. (It is *not* switched to suspend or somesuch by DPMS; I didn't wait for that turning black in all tries described below) I can login on a console into the system.
System Intel CPU Core2, E6750 Suse 11.4, 64 Bit (both original and backup system) Kernel: Linux 2.6.37.1-1.2-desktop x86_64 (backup system) / vmlinuz-2.6.37.6-0.5-desktop (original system) KDE: 4.6.00 (4.6.0) "release 6" (on the the backup system, because I don't know how it get the info as long as I can't login to KDE)
