Ubuntu problem

I’ve now been running ubuntu for about 3 weeks, but this morning when I tried to log in I got an error message:

User’s home/.dmrc file is being ignored

Luckily I found this thread http://ubuntuforums.org/showpost.php?p=2427423&postcount=2

by a user called aidanr which told me to input the following commands which seemed to solve the problem  .phew!

sudo chown -R [username] /home/[username]

sudo chmod -R 755 /home/[username]

sudo chown [username] $HOME/.dmrc

sudo chmod 644 $HOME/.dmrc
