In this section, we will cover some material about X applications that are neither KDE nor GNOME applications. As should be clear by now, you can run these in any of the desktop environments without problems, even though they might not be as integrated.
We’ll particularly spend some time with one aspect of older X applications: X resources, a very powerful, but also confusing and difficult-to-learn way of customizing X applications.
Before we tackle the X resources, one more hint: many programs described elsewhere in this book are X applications as well and are run in an X environment (whether it is KDE, GNOME, or something else), just like the programs described here. And there are literally tens of thousands more out there on the Net — yours to discover!

or if you have to deal with
applications that aren’t well integrated into your
desktop, you will be asked to deal directly with X resources; they

classes of clients; for example, we could set the default font for
all invocations of xterm to
