We run Linux Mint. This came about after the newer Ubuntu release had the new Unity menu system that nobody on the farm liked.
Mint comes with a text editor of course, but we found something much better.
Search your software manager for Medit.
Medit not only does a great job for editing text and shell scripts, but it also has some other nice features. Among them, an integrated terminal button, to run stuff from the command line. Saving documents with languages like Japanese or Chinese works flawlessly with the encoding that the software uses.
Also, Medit speaks several programming languages, like PHP and HTML. This makes it easy to find missing brackets and other flaws in your code!
