Using Dual Displays on Linux

“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 1280×1024 (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 1280×800, and the external displays are
1280×1024 or more.”
