Nov 10, 2010

Looking for a visual login method for Gnome/Linux. Such as the droid has, the 9 squares that you use your finger to slide over and connect.

Even better if it is required at the same time a regular password is entered.

Ubuntu Installation :: Unplanned Visits To Login Window - Taken To Login Screen Three Times

Aug 18, 2010

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.

Ubuntu :: Unable To Login / After Couple Seconds Returned To The Login Splash Screen?

Oct 10, 2010

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

Ubuntu :: Slim Login Manager Preventing Computer From Booting To Login Screen

Aug 4, 2011

yesterday i installed slim login manager on my computer (eee pc 1018p, ubuntu 11.04), and now it cannot get passed the ubuntu loading screen (with orange dots underneath) when booting. i tried booting into recovery mode and that didn't work either. i also left the computer trying to boot overnight and that didn't work.
basically, during this loading screen that should eventually bring you to the login screen, i can alt+tab to see the progress of the load. the progress is stuck on

Is there anything I can do from grub to remove slim?or, is there any way I can access my ubuntu partition and save all my files?

Ubuntu :: Login - Enter My Password To Login The Screen Becomes Black And Return Me Again

Apr 15, 2011

I just bought this desktop from my friend and it runs win 7 and ubuntu 10.04. it worked very well the first two days until I changed the hostname of the system.

I did like: hostname myNewName

And everything worked fine. The problem now is when I start ubuntu and and reach username and password screen , I enter my password to login the screen becomes black and return me again to the screen where I put my password again. If I entered wrong password , the system message stating wrong password. On the other hand, when I try to run ubuntu from live-cd I can login easily and access my account.

My friend told me he removed Naultius package and reinstall it for some reason before he gave it to me. Note windows 7 is working properly.

Ubuntu Installation :: 9.10: Login In Just Brings Me Back To Login Screen?

Jun 5, 2010

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

Ubuntu :: Login But Almost Immediately Kicks Back To The Login Screen?

Sep 28, 2010

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.

Ubuntu :: Freeze After Login In 10.10 (no Mouse Movement And Only Login Bg Visible)?

Feb 15, 2011

I installed xorg-edgers around the time the issue started, but I install and uninstall packages so often its hard to tell if this was the cause. Regardless, I ppa-purged the xorg-edgers ppa, reinstalled the proprietary nvidia drivers, and created a new user account, to no avail. I also wiped the /tmp directory, and reinstalled compiz, and tried dpkg-reconfigure -phigh xserver-xorg.

So far nothing has worked; I've checked out dmesg and /var/log/syslog, and nothing seems to be amiss, but admittedly I'm not sure what exactly to look for. I have a feeling its an issue with X being broken now, regardless of my attempts to downgrade, but I don't know how to go about correcting it.

Ubuntu Security :: Bad Login Protocols - Graphical Login For Gnome Sizes Itself To Accommodate A User's Exact Password Length

Dec 14, 2010

I'm seeing really bad user login format under a standard installation and am wondering why ubuntu does this as default. I have noticed that the graphical login for gnome sizes itself to accommodate a user's exact password length. This indicates to me that somewhere on the unencrypted part of a standard installation with user encryption contains at least some indication of the content of the password length which seems a security flaw even if not a complete hole, it majorly reduces the number of attempts a cracker would have to cycle through.

And that's assuming that *only* the length is contained. Furthermore it seems that it would be MUCH better to simply display the number of characters entered into the pw field and allowing the gui to expand itself from an fixed size as the field is filled out so the the user still receives visual feedback for entering characters. Either a simple character count display should be entered into the field or a 10 dot to new line so that one can visually quickly count the number enter by multiplying from a 10base graphical observation.

Ubuntu :: Run Application Before Gdm (login Screen Or Auto Login)

Feb 22, 2010

I have program that work like Fedora Firstboot it's run only one time after finish installation. I have two questions to ask.

1. How can I start this application before gdm start (login screen or auto login)

2. How can I start this application in fix display resolution (800x600)

My method now is

(This is a part of script , this script execute from /etc/init.d/myfirstboot , I create symlink to /etc/rc2.d/S1myfirstboot for start it before anything)

gdm-stop # first time I use /etc/init.d/gdm stop
DISPLAY=:1
export DISPLAY
/usr/bin/Xorg :1 &

[Code]...

I don't understand why first time firstboot start the system will auto loging in but not complete yet and then my script is start and it's work does not fine I think that is another user is already login , but if I re run my firstboot again and again (by setting something that can revoke my firstboot and restart) it's work before auto login and every things is ok!

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.

Jul 13, 2010

I'm hosting a server with Ubuntu 10.04. I've stumbled upon a strange problem.The server seems to refuse any login attempts, either with SSH or via a TTY after a reboot. After a couple of minutes (about 10 minutes or so) I able to login. The memory usage isn't high at login nor the system load. The auth.log doesn't show any login attempt before.problem? Or does anybody have a suggestion I could try to fix this?

Fedora :: Can't Login Into The Root Account: It Returns Me Immediately To The Login Prompt?

Jan 27, 2010

I just installed Fedora 12 on a laptop. I changed the default shell on the root account to /bin/tcsh and changed the runlevel to 3 and then rebooted. Now I can't login into the root account: it returns me immediately to the login prompt and I can't see any error message (the screen is cleared).Why is this happening?Can I boot into some sort of safe mode so I can undo my changes to the /etc/inittab and /etc/passwd file?I tried booting with a Live CD with the intention of mounting the filesystem and making the changes, but the new filesystem is a LVM and it won't let me mount it (or I don't know how to mount a Logical Volume).

Fedora :: FC9: Forgot - Partition Doesn't Work - Can't Login At The LUKS Login After Grub Starts

Feb 15, 2010

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
