I have a problem with my account 1 day ago I changed my password and than I forgot my password. I check some solution in many website and I found something as follow:

  1. Enter to grub and selected Advance option for Ubuntu.
  2. Selected Ubuntu,with Linux\ 3.8.0-11-generic (recovery mode)
  3. Than I selected root Drop to root shell prompt
  4. Then I write these commands mount -rw -o remount /
  5. Then sudo passwd -u (my account username)
  6. Then passwd (my account username)
  7. Then vi /etc/lightdm.conf
  8. Then greater-show-manual-login=true

And I saved the new configuration but, after restart I was unable to login when I logged in and add my password there was a flash black screen and I was back to the greeting screen? please tell me the solution

Seems it tried to find you home directory when the monitor flash black screen.

Using Ctrl+Alt+F1 then login with your username and password if you found error can't find home directory you need to set home directory by using following command.

sudo usermod -d /home/user user replace user with your username

But if there is your home already, please check disk space. Low space is also the root cause of this kind of issue.
