Hi!
I've a dual-head hardware device (with 2 framebuffer devices: /dev/fb0 and
/dev/fb1) where I want to run one process per framebuffer device with DirectFB
Multi Application Core. I've installed the kernel fusion driver. The
framebuffer devices have different modes: fb0 = 1024x768 and fb1 = 640x480.
I wrote a driver for the dual-head hardware device with rectangle fill and line
draw. I start my applications as:
$ app1 --dfb:session=0 --dfb:fbdev=/dev/fb0 --dfb:mode=1024x768
and
$ app2 --dfb:session=1 --dfb:fbdev=/dev/fb1 --dfb:mode=640x480
But I'm unable to get my setup running. Either I get
"Core/Graphics: Could not lock GPU!"
and then I've no acceleration or the applications hangs directly after start or
I get

(The same happens with DirectFB 1.1.1 as well)
How can I get my setup running? ANY hint is appreciated.
