Went I go into terminal
Top left:

Ubuntu 14.04.1 LTS T160 tty
Hint Num Lock on
T160 login:

I now remember my full user ID [emoji15]
After typing from other post Sudo visudo

On screen shows must be root to edit visudo.

Don't know how to get to root login.
Have tried
T160 login: Sudo
Pass: xxxxxxxx

Then I get Login incorrect I know this is the right password.

Don't know why this has happened!  Didn't do any update.

Thanks for help

At the point you are, you have to write your credentials, username and password to login in. After that, there will be a prompt to do what you want.

I want to fix my computer!
I woukd judt install lite again but don't want to loss data,  as I ran out of diskspace I was using the disk os was installed on.

Is any clue why this happened?

In my opinion, that's a bug of lightdm. If you login at the terminal you can try to give

Code:

startx

and see what will happen.

Startx
Made every thing come back desktop icons background tool bar .. then did an system update then shut down.

Code:

startx

works nicely, so I did all these with Root (install updates, shutdown) but still have the lonely mouse pointer case, luckily not with simple users.

Maybe after installing any updates one should asap shutdown with root, or should one omit using root for this - and all other - purpose(s)?

Reboot did fix for me I did a full shutdown.

Solution for me was to add sleep 2 to the /etc/init/lightdm.conf file as described here http://www.webupd8.org/2013/01/ubuntu-li...using.html
