Oh, and I forgot to mention that if your distribution does not support the
newer versions of XRandr the appropriate course of action to take is to
turn off libkrandr and krandrtray completely.  I do not want to get into
legacy support of older, possibly malfunctioning graphics subsystems
unless I am paid to do it! ;-)
