i will show you how to display whatever font you want on your desktop,taskbar,menus etc...
This was done in ubuntu 7.10 gutsy, I use gnome environment and I do not know if it works for other versions or kde.
I am very new to Ubuntu and still learning it,
i love to modify everything, so i began my quest to have old English fonts . I see lots of people asking in posts for the same thing but no definitive tutorials or confirmation on being able to do it.(not in my searching anyway) So i gathered the info i could find and experimented till i got it. if you need to find what version of debian you are using, go to taskbar, system,administration,system monitor, when it opens you will find your version in the systems tab(see pics)
Step 1: Root permissions
next to do is for later in the instructable,but we will do it now so its ready.right click on your desktop and select create launcher.type root in the name box, then type gksudo nautilus in the command box. now you have a shortcut to root privelages on your desktop.
