Installed Slackware 13.1 in my Desktop today. Everything went fine unless I found that I couldn’t log in as normal user to the desktop environment! Yeah, the super-user could.
Also, the user didn’t have a home directory made, by default! (but the /etc/passwd file showed /home/user directory as the home directory for the user).
So what? Every time I tried logging in as the user to the desktop environment, it said, No Home directory Found. It also said kstartupconfig4 does not exist or failed to load.
Solution
I manually created a home directory under /home
sudo mkdir /home/username
Now for the kstartupconfig4 issue, I found the solution after a bit of Googleing.
sudo chown -R username.username /home/username
This transfers the ownership of the home directory of the user from the super-user to the user.
I don’t know why a home directory wasn’t created for the user by default! 
But wait!!
All this happened b’ cos
useradd username
was used to create the user account.
Even
useradd -d /home/username username
failed to create a home directory!!!
But the following command worked fine
adduser username
!!!
Happy Hacking & Googleing!!
