Good morning all,

Let me start by saying that have been using Ubuntu for a while now and enjoyed the experience this far.

I upgraded to 11.10 last year and was happily chugging along until I decided to change my background image this morning.
I thought I would delete the one I was using and replace it with a new one ... BIG MISTAKE!!!

As I deleted the one I was using my system just froze (HELLO WINDOWS) and now it's just frozen :(

I shut the system down (forced shutdown) but now I cannot log into my main profile ... It just hangs.

Can anyone please help me?!

Can you login with a live CD and backup your home directory before you do anything else?

That way as a worst case you can reinstall then restore your home directory.

Can you force the machine to boot in safe mode and then carry out either a roll back or fix at that point? My dual boot toughbook (with XP) offers the choice but I'm on 11.04.

That could be the answer ... how do I boot into "safe mode"?

This is an educated guess based on 11.04.

2 options are either:

On start up, during the boot sequence you get the choice to boot in safe mode or even last known good state. You might have to use an F key of some kind to stop the boot process and go down an alternate route

Second option is (if you have a log on screen with password) is instead of using logging on, you have an options or power button. Here you may have the option to restart in safe mode or log in, in a different mode.

Suggest you have a quick search for safe modes for 11.10 to confirm what options you have none the less.

OK ... I've made a startup disk and busy saving my "home" directory.

Although I cannot backup or copy my "home" directory. I get the error message that I do not have permissions to read it.

Sorry - tried to PM you but can't. Are you able to log in as you on the live CD and thus own your home directory again. Otherwise you will have to give yourself superuser status.

You should be able to find some hints in here about moving your home directory.

I Think the only really sensible option is for you to pray for forgiveness for installing open source software I suggest you sell your soul and join us poor tormented souls back in the windows OS world, where their is such things as system restore and repair windows from the boot disk/cd/other. or the magic press F8 to reset back to default config.

Can you use the live cd to just put the (or a) image back where the system is expecting it to be?

It seems weird that deleting a background image could do that.
Can you even login as root, or do Ubuntu security defaults not allow that anyway?

However, backup home directories first (one way or another) is a good idea. Then perhaps if you know the filename of the deleted image, I wonder if putting the image back (or another with the same file name) will fix the problem?

LOL after 6 years of Linux (3 different OS's .. Mint, Fedora & Linux) I think I'll keep up for a fix.

Thanx for the suggestion though, :)

I suppose I could ... If I knew how ...

Lo-tech way out is create a new user (from the commandline if neeed), and copy your data across to it if you need to.

Hi all.
Thank you for all the advise and help. In the end all I could do was re install the OS.

I tried fixing it from the CD but it continued using the old Unity setup.

So now I have a fresh install that works 100%.
