c. When you are at the Login dialog select “user” and enter the password you selected
in step 2 to login “user”.

c. Right-click again on Terminal and select “Add this launcher to desktop”.
3.2.3 Install Necessary Packages
LTIB will require a number of packages to be installed in your Linux distribution before you can actually
use LTIB. If these packages haven’t been installed LTIB will usually complain and list the packages
that are missing. LTIB could also fail without listing any package. The instructions below install the
packages that are missing in the Fedora distribution we are using.
