Hi,
there is a permanent warning during starting ddd:

Warning: Could not load font
"-*-lucidatypewriter-medium-*-*-*-*-120-*-*-*-*-iso8859-*", using font
"fixed" instead
Warning: Could not load font
"-*-lucidatypewriter-medium-r-*-*-*-120-*-*-*-*-iso8859-*", using font
"fixed" instead
Warning: Could not load font
"-*-lucidatypewriter-bold-*-*-*-*-120-*-*-*-*-iso8859-*", using font "fixed"
instead

To searching for the solution I found this page:

However is not clear for me where can I actually find these fonts and how do
I install them.

Thanks in advance,
Steve
