But wen i try to enter password in the terminal(especially wen doin sudo commands) it doesnt get entered(the cursor doestnt move).

wen o type password in the terminal nothing gets displayed(i mean cursor remain there itself without accepting the password).i typed the password(i coudnt see it) and pressed enter . it says wrong password.

try using su instead of sudo.

the password will not display when you type...will not even show ***** like other places you enter a password...this is a security feature so someone looking over your shoulder wouldn't be able to tell the number of characters in your password.

edit: use of su above is not correct - sorry

To change your password, you have to use the "passwd" command. If you did not use that command, then you did not change your password.

As almax00 says, you will not see anything on the screen when you enter a password in the terminal. But it is recorded by the system, so when you press "Enter" it is accepted (if you entered your password correctly).

Also, remember that Linux is case-sensitive. You must enter your password EXACTLY as you first created it.

One more thing - keyboard layout! Check it first, before entering password - I found a strange bug in ubuntu, where part of the keyboard (about 1-2 keys) cannot change away from slovak, while the rest of the keyboard switches between english-slovak correctly.

Wow - I never even thought of that! If you're using multiple language keyboard "layouts", you sure as heck better be putting your password in with the same layout that you used to create it/change it last!

Kubuntu doesn't recognize the "su" command, you have to use sudo (you can run as root with the code "sudo su", but you still have to use the keyword "sudo"). Try using the sudo command again, and when prompted for your password, very carefully and slowly type it in (being mindful of upper/lowercase letters and symbols).

Edit: I do agree with you, however, if that bug does exist (very unlikely, put possible nonetheless), and I ever do get it, I would most definitely go mad.

Re: U will go mad wen u get this problem!!

I recently had a similar problem, and I'm I've been using Kubuntu/Ubuntu for quite a while. On on of my PC's I logged out of Kubuntu and restarted to log into XP. The Windows login page would not take my password. Tried everything. My windows password is all alpha characters and my Kubuntu password is all numerical. Drove me crazy. On a whim, I switched keyboards. Fixed the problem. The keyboard I was using was fully functional in Kubuntu, but for some reason, it was not working in windows. Strange eh!

There is only one instance where the su command is understood in (K)ubuntu.
That is if you are root. (Terminal: sudo bash).
To revert type in terminal su [name].
