Fvwm With Xrandr, Problems on 1.1.0beta1 Options

[Christoph]

Hi developpers,

after hours of searching and trial and error I finally give up and ask you for help. Perhaps someone knows what I am doing wrong.
Some time ago I hacked a bit with fvwm to make it support xrandr, i.e. the viewport gets updated and the menus show up in the
right place. This hack worked fine with Angstrom (->xorg-1.3.0.x). But as this distro does not have the applications I want I switched back
to pdaXrom 1.1.0beta1. And here (->xfree-4.4.0) xrandr does not work. The problem is especially that the event is promoted to fvwm, but
the XRRScreenChangeNotifyEvent does not have the new width and height. Consequently DisplayWidh(...) does return the old width
even after having called XRRUpdateConfiguration(...). On the other hand the field "rotation" is updated.
Does anyone have an idea why?
One more information: I installed icewm from the feed which supports xrandr well. If I compile it myself it has the same problem.
Perhaps it is just a matter of compilation options?

I'd really appreciate if someone could help.
