You know, I'm really pissed. That KRandR kded module (aka "Detecting
RANDR (monitor) changes") is *not* in KDE proper but only in an
obviously unfinished working branch of the KWin lead developer, Lubos
Lunak. See
http://websvn.kde.org/branches/work/~seli/randr/module/?revision=864812
for the current location and contents of that code.
Congrats to Kubuntu for including unreleased code that explicitely
specifies critical sections as "HACK", well done. The last commit (6
weeks ago) even disabled that timer, quote:
(...)
#if 0 // xrandr apparently can't detect hw changes and on some systems polling
freezes X :(
QTimer* timer = new QTimer( this );
timer->start( 10000 ); // 10 s
connect( timer, SIGNAL( timeout()), this, SLOT( poll()));
#endif
(...)
I suggest you people update the package to current SVN and leave it with
that for Intrepid, so that not more damage is done than has already been
inflicted. It won't work for events that happen during a KDE session
then, but at least it doesn't break lots of systems in various subtle
and annoying ways. Guess there's a reason that Lubos didn't include this
into standard KDE packages yet.
