cant log imto desktop

Can you identify whether the password prompt is caused by the BIOS or by the installed operating system or software?
Maybe you should post a picture of the screen on some image hosting service and providing the link address that we can see what it looks like.

I think this is a software issue. I have gone into the BIOS and removed all passwords.

So, I have access to the terminal and have been getting a lot of error messages. I read that 16.04 moved away from upstart to systems. So I removed upstart and installed systems.

Now, when i put in the password the greeting screen goes away but all that is left is a blank wallpaper.

I reinstalled unity, the display manager and windows manager and reconfigured the graphics and I'm just running out of ideas.
I can take a photo on my phone but how to I post the photo here

Thank you

If you want to post an image of your screen, then you have to upload that picture to any image hosting service of your choice, and post the link to that image page in the answer document.

I assume you are talking about systemd as replacement of upstart, not systems.

By the way, I see that you have several question documents open, one of them telling that you have gone back to Ubuntu 14.04.
How does this question fit together with that other one? Are you talking about the same system or different ones?

Thank you for your reply.

No, I have not gone back to 14.04. I was asking if it was possible since I am having so many problems getting into the desktop.
I have so many open questions because there was no replies and so, I was asking the question in a different way to see if I could get some help with my problem.

I tried to switch from upstart to system because it said that Ubuntu switched over in the 16.04 version but even though my desktop says it is 16.04. it was still using upstart.

I have deleted all passwords in the Bios but the computer is still asking me to put the passwords in.
I have deleted the lubuntu desktop I installed but it is still on the desktop. I do not know what to di about this.

Ok,
Thank you.

Is there any additional text to the password request? Can you identify whether this is still some kind of BIOS password request, or maybe a disk encryption password, or is it the Ubuntu login that asks for the password?

At what moment does it show up, before or after a grub menu?

Please provide more details.

I think this a software problem.

I went into the BIOS and removed all passwords so there are no more passwords.

When I first installed. Ubuntu, I set up an encrypted password for the hard drive and an administrator password for the desktop.

I removed these passwords.

But now, when the computer turns on, it still asks me to put in the encrypted password. After the system starts, it god to the grub menu. The screen sits there for about. 15 seconds then moves to the desktop where I see the login screen
At the login screen, I am asked to put in a password.

But as I said before, I purged out the lubuntu but I still have a blue screen that says lubuntu 16.04
But my updates say oubuntu.

Something is wrong somewhere.

I assume that you have instructed the Ubuntu installer to encrypt the hard disk partition(s). Now whenever you boot the system you have to provide the encryption pass phrase. That is something that cannot be easily changed.

How did you "purge out lubuntu"?
You most probably did not change the system background image from the Lubuntu image back to the standard Ubuntu one.
(Try right click on the desktop, select "change desktop background" and select the standard Ubuntu wallpaper.)

I deleted the hardrive password. It should not be one. I looked into the bios and it says there is no hardrive password. Bot I am still asked to put one in.

Right now, there is no desktop. I only see a terminal. So I can't right click anything.

Do not confuse the password that you can set in the computer's BIOS to prevent unauthorized access to the hard disk, with a passphrase needed for software-based encryption/decryption of a disk partition.

If you log on in the virtual console and issue the command

sudo fdisk -l

what do you see?

Maybe the fastest solution to your problem is a complete reinstallation of Ubuntu, without activating an special features like disk encryption, switching from upstart to systemd or other actions. Do you have already stored private data on your system?

Well, I have fixed the password problem but I have other issues now.

I used my 14.10 Ubuntu disk I bought and set the BIOS to boot from the disk.
The install ran for 4 minutes and got stuck for 2 hours.

I cancelled the install and re-tried but the same thing happened again.

So, I installed Fedora 21 that I had on my Ubuntu 14.10 disk.
The install went well and now I have Fedora 21 but it didn't install drivers for my wireless card.

I can't find a way to get the wifi going and I don't have a hardwire connection.

I found someone who posted some commands to install drivers by saving them to a flash drive then save them to the computer .
He said open the terminal and change the saved commands to a directory and said from there I cold install them through the terminal but I don't know how to do it.

Do you have any ideas how to fix this?

Thank you

If you are now running fedora, then we cannot help further.
Fedora is different from Ubuntu (e.g. has a package management system based on rpm files, and not deb files).
Please contact fedora support http://ask.fedoraproject.org/ or any other suitable page listed on https://fedoraproject.org/wiki/Communicating_and_getting_help

I do not want Fedora.
I like Ubuntu but I could not get it to run even from the live cd.
I only installed Fedora to see if the problem was with the disk or with Ubuntu.
Since Fedora installed, the problem must have been with Ubuntu.

No that I have a desktop again, I am going to run the live cd and try installing Ubuntu 14.10 again.

Ubuntu 14.10 is not supported any more.
You should use 14.04, 15.10 or eventually 16.04

Thank you.
