How to Completely Remove Macbuntu – Formatting Included

I cannot test this, but I think it's worth a try. Without logging into X, switch to a console CTRLALTF1. Log in, make a directory to store your current home directory, and then modify the account to move the current home directory.

sudo mkdir /mnt/tmp
sudo usermod -d /mnt/tmp/$USER -m $USER
logout

Login again without X. Define your home partition in /etc/fstab.

sudo vim /etc/fstab

It might look like this: /dev/sdb1 /home ext4 defaults 0 2. When correctly defined, mount it, make sure permissions are ok, modify the home directory again, and then move the files from the old home to the new home.

sudo mount /home
sudo chown -R $USER: /home/$USER
usermod -d /home/$USER $USER
logout

Log in again with X.

sudo mv /mnt/tmp ~
sudo chown -R $USER: /home/$USER/tmp

Does this work as intended?

OR

You can create a new directory, like /users. Mount the disk inside users. Change permissions on /users/$USER to match your username, and then change your home directory path with usermod.

This is rather simple and effective:

1. While editing your theme open a Nautilus window
2. Kill Nautilus with killall, then open nautilus from the Terminal
3. Make your changes to the theme and kill nautilus again then relaunch it

You can see the changes you made witout doing anything difficult. Most elements that you change of the theme will reflect in Nautilus.
