Using Dual Displays on Linux

(Other stories by JA Watson)

"I have been using dual monitors on a variety of Linux systems for quite some time now. The most common case has been using a laptop with an external display attached, but I have also done it on desktop systems with two displays. Overall it works very well, and if you need the additional working space it is a wonderful solution. Here is a brief description of the things that need to be considered and configured.

"The first major consideration is the resolution of the two displays to be used. If you are fortunate (or careful), they will both have the same resolution, and this whole issue disappears. This is often the case with desktop systems, where you might connect two identical displays, or at least two 1280x1024 (or whatever) displays. This is often not the case when a laptop display is one of your two, as they tend to be lower resolution than common external displays today. In my case, the laptops I most often use these days are 1280x800, and the external displays are 1280x1024 or more."
