Xconfigurator shouldn't print its entire list of monitors and cards. I
count 4157 lines with wc -l, and the useful part of --help's output is way
off the top of the console.
We (Red Hat) should really try to resolve this before next release.
Fixed. There are three new options in the new version which will allow the
monitors, cards, and servers to be displayed instead of showing all of them when
using the --help option. The version which fixes this is 4.9.2.
