How remarkable.  I shouldn't open my mouth (at least figuratively) without
checking my facts.  My experience with KDE apps has always been that
attempting to run them under sudo results in something like "unable to
connect to display 0:0", unless you do something with xhost, whereas kdesu
handles it.  A quick attempt to "sudo kate" resulted in "ERROR:
Communication problem with kate, it probably crashed" but not the "unable
to connect" message, otoh, "sudo kcontrol" seems to work fine.

Still, I'd recommend "kdesu" for starting up X apps as root, rather than
sudo, just because it _always_ works.
