Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

It's the first time this happened. On regular terminal my login works great, even as root. My user name is always the same (Júnior) and login in never was a problem. I even tried setting the root passwd but nothing helps.

I cant login normally in the Terminal in both my username and as root.

BTW this happended after I started to install the system with a 21 characters password with numbers (upper and lower case) and symbols = (example) - fR81@@#$Jjase(*81$4

Any help?

Ubuntu 12.04.1 64bit/ Encrypted home folder/ sysctl -w kernel.shmmax=128000000 (to get avast working)

Welcome to Ask Ubuntu! We really need more information regarding your question. What do logs say (/var/log/syslog, /var/log/auth.log) around the time of the error? What version of Ubuntu are you running? A lot has changed since the introduction of ConsoleKit and Upstart regarding the virtual terminals. Can you reproduce this in a clean/other installation or just on yours? –  gertvdijk Jan 11 '13 at 18:43
Hi. It says "login incorrect" Ubuntu 12.04.1 64bit –  Júnior Jan 11 '13 at 18:44
Logs don't just say "login incorrect". This is what you could see there: 'pam_unix(login:auth): authentication failure; logname=LOGIN uid=0 euid=0 tty=/dev/tty2 ruser= rhost= user=gert' <-- these lines are interesting. Remove private information if any. And please edit your question with new information rather than posting comments. This is a Q&A site, not a discussion forum. Thanks! –  gertvdijk Jan 11 '13 at 18:46
Sure, I thought you asked what the tty1 said. –  Júnior Jan 11 '13 at 18:50
I believe the problem is with the accented u character and unicode support in tty. See this question –  chaskes Jan 11 '13 at 19:27
