failed login ubuntu 12.4
 
Hey, complete novice here!! or idiot lol!

I created my ISO disc and behold it worked.Well up to the point i had to login .
In tiny script at top left corner of screen LOGIN appears.so although not asked i entered my user name...then i was asked for my password.....i attempted to enter my password but nothing could be entered in the space provided.

Please can any one help?
Best Regards

I sounds like you are trying to log-in to Ubuntu using a terminal. After you enter your user name and it asks for your password, go ahead and type it in and hit enter. You will not see any entry or movement and nothing will happen until you hit enter.

Hi and thanks for your reply.

After completing the install from the ISO I had created,I removed disc and done a restart
to boot from Ubuntu.


Was then presented with a black screen.In the top left in very small font was selection
Ubuntu....Windows xp pro.
Selected Ubuntu.

Now presented with black screen worded Login.

However was not asked for name followed by password? as is usual in most logons.

Just said Login .

I pressed enter thinking I may open a proper login window instead was told login failed.

So went back and where it said Login entered my name where upon was asked for password.

However it would not allow me to enter a single font?


And that is exactly what I attempted to do to login.


Have read several other peoples reports of similar problems.

Am new to Linux and keen to get started.I have Avast anti-virus for windows onboard a new 1 TB HDD Nvidea geforce 9600 gt graphics,Twin core Intel Pen 1V 3.5 mh 32bit system. I thank you for your response Best Regards.

When you are at the Login prompt type in your Username.
Than type in your password and hit Enter.

When you are typing in your password are the characters moving or no, not moving?

gold_finger 03-30-2014 09:34 PM

Adding to above -- make sure username typed in all lowercase letters.

Hi Ztcoracat Goldfinger.

Thanks for responding.

Yes I typed in my user name ..enter.. then I was asked for my password.....but it would not let me .type in the password.

Best Regards

I'm not sure why the characters are not moving while your typing in your password. When I had that happen I re-booted my system.
It could be that your keyboard isn't getting recognized--
Make sure your keyboard is snugly connected. (Unless it's a laptop)

There is another way to log in.

1. Once the GUI (your desktop envirnment) is up hold down Ctrl + Alt + F2.
When you do that it will go into console mode. You'll have an all black screen with white letters.

2. Type in your username at the login prompt and hit Enter.

3. Than type in your password and hit Enter.
***Also, there is a default behaviour, you can't see the password in the terminal, not even astericks. Just type your password and hit enter.***

4. Type startx and hit enter. That should boot you into the GUI and you should see your desktop.

--- Is this a Desktop PC or a Laptop?


*** gold_finger:;)***
What are your thoughts? Reset password? or Recovery mode?

gold_finger 03-31-2014 09:48 AM

@planet b,

Try what Ztcoracat just suggested to get logged in.

If that doesn't work, try booting in "recovery" mode, described here: Booting into recovery mode.

If you get in with either method above, run the program that looks for proprietary drivers and install the Nvidia driver marked as "recommended". Not sure what program is called -- could be "Driver Manager" or "Additional Drivers", etc. If can't find, just type "Drivers" in Dash or application menu search box and it should return what you need. (I'm not that familiar with Unity, so not exactly sure of terminology.)

Reboot after Nvidia driver installed to see if that cleared up the login problem.

If no-go on above, post back with answers to following questions:

1. Have you tried choosing Windows XP from the grub menu?
2. If "yes", does it work to boot into Windows?
3. Did you do a test run of the live Ubuntu system before installing, or did you just start the installation as soon as it booted into the desktop?
4. Did you have the installer encrypt the disk or /home partition during install? (Doubtful since you didn't mention that, but can't hurt to make sure.)
5. Open a terminal and enter the following command, then copy/paste output back here for us to see:
Code:

inxi -Fxz

@Ztcoracat,

I'm not sure what to think -- could just be the missing Nvidia driver. (We'll find out if able to get it installed.)

I would have thought possible keyboard recognition problem also, but if that were the case then even typing in the username wouldn't work -- which does right now, if I understand things right.

In Mint, which I'm more familiar with, there are times (for whatever reason) that grub doesn't get installed properly during installation. It's just a long-shot guess, but maybe that happened here too. (If it boots Windows, then probably not the problem.) If so, reinstalling grub from live DVD or running Boot-Repair utility from live DVD will fix that.

Another guess (since this is an XP computer -- likely older machine) is that the specs of the computer are not up to handling the Unity desktop. Mint's Cinnamon desktop causes similar problems on lower spec systems, so that could be what's going on also.

Ztcoracat 03-31-2014 02:52 PM

I agree with you gold_finger-;)

Could be a grub issue or his PC doesn't (possibly) work well with Unity.

TroN-0074 03-31-2014 04:05 PM

While typing your password the charecters are not showed, that is normal in a linux terminal so just type your password and press enter. However in Ubuntu you should be booting into a graphical interface. It would boot into a terminal only if the configuration of the graphic card was no done correctly

What video card do you have in your computer? Also if you login you need to run all the updates available that might fix some problems.

gold_finger 03-31-2014 05:11 PM

@planet b,

After TroN-0074's post above, I went back and read your responses again because that has been pointed out to you before. I couldn't determine from your answers whether or not you did try doing what they've told you or not. You just keep saying that the computer "won't let you" put in a password.

Rex Bouwense, Ztcoracat, and now TroN-0074 have tried to tell you that NOTHING is going to move and there will be NO NOTICEABLE EFFECT while typing the password -- it will appear as if nothing is happening. That is normal. That is what it is supposed to do.

Have you or have you not typed the password and hit enter (even though you don't see anything being typed on the screen and it looks like it "won't let you")?

If you did try and it didn't work, double check that your CAPS LOCK key is not on. Anytime I've had problems logging in it's because I accidentally hit the CAPS LOCK key.

If none of the above made any difference and you still can't log in, go through items on my last post.

Thanks to you all for helping me. Goldfinger-Ztcoracat-Tron-0074

To answer some of your questions Yes I did enter my user name followed by my password.
My user name appeared when typed in.
My password did not Which you state does happen.
I used lower case for all.Then pressed enter.
I was informed that login had failed.

On the login menu for grub, XP appears and yes I can boot into XP from there.
Caps lock is off.
I am on HP Pavilion Media Center Desktop Pentium IV. 2gb ram,Dual core Intell 3.5 mh.32bit system. 1 TB hdd.Nvidea Geforce 9600 gt graphics.Updated driver last month. Avast anti virus.(which is turned off at install time).

I have decided to load this to my hdd have created a 4.8 gb Primary drive formatted to fat 32. (I hope thats big enough for Ubuntu 12.04.4 ?)

I believe Nvidea have a special driver for Linux will grab that tomorrow also.

Yes will be trying your tips suggested earlier,about logon.


I do appreciate your help.Feel confident will crack it soon.

Best Regards to all.

planet b,

Thanks for detailed response. Those are the kind of details that help us make more informed suggestions. Sometimes things that seem minor, or unimportant to the person posting can be eye-openers for the people responding. Here's one such example:

Two things that may be clues for your problem in above quote:

1. 4.8GB is likely too small for Ubuntu installation. If the install actually did fit there, then there is probably no room left for doing anything else.

2. I've never even tried to install Linux on a FAT32 formatted partition, so don't know from experience if it would even allow itself to be installed on one. If it did allow you to install on a FAT32 partition, then that is probably the source of your problems.

Linux file system sets various permissions for different files. FAT32 does not allow for setting those Linux permissions on the various files.

Let's see if we can find out for sure how the install was done. Once we know that, solution should be easier to know.

First, think back to your Ubuntu install.

Do you remember if you booted the computer directly off of the Ubuntu DVD/USB (not going into Windows at all) for the test run and installation?

Or

Did you boot into Windows, then load the Ubuntu disk and run installer that way?

The two scenarios above will result in two completely different types of installations.

Did you use Windows, or a Windows-based program to make the partition for Linux ahead of time?

Next: Boot into Windows, go to Disk Management and take a screenshot of the partitions on the drive. Post that back here for us to see.

Last: If you can boot directly off of the Ubuntu live DVD, do that. Then open a Terminal and enter the following commands one-at-a-time:

Code:

sudo fdisk -l
(Lowercase "L" at end of fdisk command.)


Code:

sudo blkid
Copy/Paste the output from those back here for us to see.

Ztcoracat 04-01-2014 07:56 PM

The output of fdisk -l will be very helpful--

Ubuntu needs at least 18 to 20 GB for the (/) EXT 4 journaling file system and 1 to 2 GB for the swap:-

@planet b: Your output from sudo blkid will look similar to mine on my system-
The first line is my journaling file system at the moment is Voyager 12.04 3.2.0-60 generic:-

Code:

/dev/sda1: UUID="7e700542-69d5-4922-937b-b6ce34ecdff4" TYPE="ext4"
/dev/sda5: UUID="1a8284c2-6423-4394-928e-ae7a32b22578" TYPE="swap"
