What account are you using?
If your'e trying to login with root you can't. root is disabled by default, you have to login using the account you created during install.

Please don't create multiple threads on the same subject.

It dilutes community effort and creates work for staff.

If you cannot login using the same account created during the installation, then you have a few choices.
a) reinstall, noting the userid and password carefully this time
b) some easy hacking of the password and shadow password files using a LiveCD. This method is very fast for someone already familar with the shell and CLI, but for someone used to point-n-click, it is likely too complex. http://www.howtogeek.com/howto/linux...m-the-live-cd/ provides instructions.
c) Find a Linux password-reset tool and use it. Looks like this method http://naveenubuntu.blogspot.com/201...untu-1204.html makes resetting a password trivial.

I would try option C first. That appears to be trivial, if it actually works. It also points out a huge security problem wiht default Ubuntu installs. Physical computer access means complete access.

Hi

i can't login with the correct password in ubuntu desktop. i cant get through. it keeps me back in to login page when I try to login correctly. please help me. what am i gonna suppose do to?

When did this start happening ?

In the session before it happened, did you install graphics drivers, any other software or have a software update ?

Are you getting any message telling you the password is incorrect ?

It sounds like X windows may be crashing.

Kind regards

Guys; 'nother thought;

Have the permissions on the .ICEauthority or .Xauthority files changed ? Could be the cause if these files are no longer owned by <the user> account. Easy enough to check:

1. At the login screen, press Ctrl+Alt+F1 to get to the console.
2. Log in there.
3. Check if ".ICEauthority" is owned by you:
Terminal Code:

ls -al .ICEauthority

4. If it isn't (but possibly by root), change it to you:
Terminal Code:

sudo chown USERNAME:USERNAME .ICEauthority

5. Switch back to the login screen by pressing Ctrl+Alt+F7 or F8
6. Try again to log in.
If it worked, see here about a possible cause:

better take a look at the permissions on ~/.Xauthority, too. It often gets changed when ~/.ICEauthority gets changed. The same fix applies.

hope this helps

~/.ICEauthority and ~/.Xauthority can be deleted safely when you aren't running X ... or just before logout. They will be recreated as needed.

The only time I've needed to remove those were after I started X/Windows from a different account by my $HOME was not reset for the other account. Basically, it is when sudo gets used when it shouldn't.

Seconded. About 8 out 9 times I encountered the error was due to the permissions of those files. Worth fixing them before going nuclear.
