[Interest] running directfb on desktop

[Juha Vuolle]

Hi,

was wondering if it is possible to run qt applications with directfb QPA on
deskop?

I just tried it but I seem to get segfault at directfb qpa backingstore
constructor
IDirectFBWindow *dfbWindow = static_cast<QDirectFbWindow
*>(window->handle())->dfbWindow();
where window->handle() is null.

Other than that there are not much errors in the startup logs (some
joystick related warnings). I see a window flashing quickly.
I was wondering if I'm missing some obvious stuff I need to setup for this
to work?

(My setup: lubuntu 13.04, self-compiled about 3 weeks old Qt 5)

any hints appreciated,
Juha

if its any use:
