SOLVED!!!! I've got it. When I install TexLive 2011 which are not in offical source, I add two stupid line in the /etc/environment, which cause the problem for months when I "apt-get" occasionlly:
sudo mkdir -r /usr/share/font/Winfont sudo mkdir -r /usr/share/font/Adobefont
Now I delete the stupid lines, and it works fine finally.
