My Lxterminal is not working.

Here's some background:

A few days ago I wanted to configure the keyboard layouts for my Lubuntu 11.10 for English and Romanian. You can find a deetailed description of what I did here: http://ubuntuforums.org/showthread.php?p=11793260

So, it worked for a few days. Today it stopped working again. So I started reading forums again. I tried to follow this forum: Switching keyboard layouts in Lubuntu 11.10 so I went up in the terminal, went into the .bashrc file and added this

sudo tee -a /etc/xdg/lxsession/Lubuntu/autostart

right after this:

setxkbmap -layout "us,ro(winkeys)" -option "grp:ctrl_shift_toggle"

Then pressed Ctrl+X and Enter.

Almost at the same time I installed some system updates.

A few minutes later I wanted to use the terminal again, and this is what happens:

[sudo] password for dora:

I type in the password but nothing happens. Also, whatever other command I try to type, it just gets returned. No errors messages, nothing.

Please help.

PS: Funnily, I just noticed that I am now able to type in Romanian again!
