"If you’re not sure what a KVM switch is, it is a device
that allows you to use multiple machines with only one monitor,
mouse, and keyboard. Some KVM switches even allow the sharing of a
single audio output source (speakers).
"There is one problem that can arise when using a KVM switch
with a modern Linux distribution. This problem has to do with the
latest releases of Xorg. Because Xorg no longer uses the xorg.conf
file, it depends upon receiving identification signals from the
monitor in order to automatically adjust the display. On a single
system/single monitor setup this works perfectly. But in some
instances a KVM switch will get in the way and the X Windows
display will be far from ideal (and some times not even usable).
How do you get around this situation? In this article you will read
a few tips that will help you get around this."
