Thanks for your help but this problem persist. When I enter the above code through xterm and keyed in

chown -R user.users /home/user/.xournal

it returned the following:

chown: /home/user/.xournal/config: Operation not permitted
chown: /home/user/.xournal: Operation not permitted
chown: /home/user/.xournal: Operation not permitted

Is there any way to solve the problem? Thanks again.
