Hi,
I've built GTK on top of DirectFB, gtk-demo works very well when I use
system=x11 in my diretcfbrc. However when I switch to my framebuffer,
also with system=fbdev I get the following error (when compiled with
the debugs on):

There was already a thread with this topic but no answers...
My directfbrc is as follow:
system=fbdev
depth=24
mode=1600x1200
wm=default
What should I check next? When I try to debug with gdb I get a black
screen and can't come back to the console...
Regards,
Matthieu.
