I was exploring my new fedora 19 after a crash in KDE (I don't know what I just did). I couldn't shutdown my laptop either with the graphical method or the terminal way (because the terminal refused to open). So I forced the shutdown by pressing the shutdown button in my laptop. After I restarted my laptop and entered my password and user, a black screen appeared and went back to logging screen again (the same thing happened with root).

So how should I fix this problem?

  • Can you access one of the ttys? At the login prompt, try ctrl-alt-F2 and see if you can log in there. If that's successful, something in X is probably corrupted.

  • Yes it was successful, and What do you mean by X ? . Now 90% i guess the Desktop environment is corrupted . Aug 25, 2013 at 7:52
  • I'm not familiar with KDE, but you can check different log files to see if there are any errors: /var/log/messages or ~/.xsession-errors (if it exists).

You will have to enter recovery mode and reset the root users password (which may have ended up corrupted). Fedora has an answer on that:

  • I don't think the problem about the passwords, Cause when i enter wrong password, he refuse to log in, but i make the right password the black screen appear. Aug 24, 2013 at 14:07
